à l'occasion de son retour
il y avait de bengaluru fini d'orages

i had given him up on and off many times over the past year
but though he frustrated me
taunted me
relentlessly
persistently driving me away in anger
i kept returning
a little broken
stubbornly expecting some deeper connection to form

tchebyshef was the natural next step for me
but as i wrote to you so desperately in the past
he was not polynomial
and so i troubled over his generalised abilities

tchebyshef was the next step in the generalised fourier
he had to be

mais il y avait d'autres beautés
que je ne pourrais pas apprécier
jusqu'à ce jour fatidique de marche

..

as i have mentioned prior
he is easy to describe in the generalised trigonometry

the first kind has an obvious definition

/ \
T | g ( theta ) | = g ( n theta )
m n \ m 0 / m 0

where g (x) is the generalised (hyperbolic) trigonometric
m 0
oo j
--- x
|0 x x \ ----
| e = (0, m) multisection of e = / (1)
|m --- j
j=0(mod m)

-+-+-

it had occurred to me early on
that there might be a secret benefit to the nonpolynomialness

a theorem in the classical tchebyshef
gave the (0, 2)-form the benefit of uniqueness
for polynomial minimax approximations
so nonpolynomialness could possibly be a path towards preserving minimax qualities

aber ich benötigte eine frische annäherung...

-+-+-

there are obvious theorems one can immediately prove from the definitions

the composition theorem

/ \
T | T (x) | = T (x)
m n \ m n' / m n n'

is simple and in many ways uninteresting
but i had toyed with it from very early on

it reveals the game
the substitution of x for g ( theta )
0 m
which is so useful to the tchebyshef generalisation

und doch nach diesem stürmischen bengaluru tag
ich sah die graue rätselfalte weg...

-+-+-

so many things to relate
i choose now only one to state

a single example to inflate
until the next
and its unending
disappointing
contribution to conflate

a simple one to start with

recall the product rule for generalised trigonometrics
comme j'ai écrit environ tellement il y a bien longtemps

watch the trick

m-1
--- j
/ |0 (n-1)theta \ / |0 theta \ 1 / |0 n theta \ |0 (n-1+w )theta \
| | e | | | e | = - | | e + / | e m |
\ |m / \ |m / m \ |m --- |m /
j=1

through the secret substitution

|0 theta
| e -----> x
|m

|0 n theta
| e ------> T (x)
|m m n

es wurde aufgedeckt

m-1
---
\
T (x) = m x T (x) - / T (x)
m n m n-1 --- j
j=1 m n-1+w
m

which reduces to the classical recurrence

T (x) = 2 x T (x) - T (x)
n n-1 n-2

for T = T (x)
n 2 n

mais la généralisation n'était pas une récurrence!

and though i have displayed here this
in the format of it's malformed tradition
the symmetry inside can be revealed

-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-
| |
+ m-1 +
| --- |
+ \ +
| m x T (x) = / T (x) |
+ m n --- j +
| j=0 m n+w |
+ m +
| |
-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-

interlocking wheels of dhamma binding the whole cyclotomic ring of places tight!

^..^

i must rest now friend
and let my newfound parasites retire

there is a much greater tale here
though
ignited by the fever of that bengalurian night

i will reveal these over the coming weeks
as my strength returns and the toxins of bharat subside

but imagine
if you will
the great power that comes from controlling the magic of this generalisation

eine zauberei von symbolen

finally
the generalised fourier theory is maturing

this new cyclic type of relation is similar
but much more general and natural
to the relations you are familiar with in modular forms and other special hypergeometrics

can you see the generalisation of jacobi polynomials?

perhaps a simpler task until i write again
can fill your exercises and prepare you for the methods

do you see how to express x^n in terms of these generalised forms?

a basic task for you
dear friend
to prepare the theory of representations and approximations

kya?

Good to have you back, even though apparently, you're not yet actually
back in a physical sense. In any case, I see you're in fine form.

Perhaps you've awoken the spirit of Ramanujan.

it would have been nice to visit kumbakonam
but i was stuck on the west side of the continent when down south

i really wanted to see places of past inspiration
to see what magic they might still hold
but i couldn't get over to ramanujan's

instead i saw the buddha's places
even though i grew tired of the buddha
after reading more of the pali canon

now i'm sick of the buddha
i've generally become quite antibodhi
and wish i could have spent some days out in the southeast

the company i work for also has offices out in chennai
so maybe one of these days...

g:

> do you see how to express x^n in terms of these generalised forms?

i thank you friend
for your long and ultimately tragic letter
on your newest theories relating
bovine flatulence and urinary tract infections
in the context of an ecosystem of pollutants

it is unfortunate that you were unable to attack
the problem of my previous letter
but your request for further elucidation and examples
shows a clear desire to understand

perhaps i should start with easier properties
working my way more slowly towards these esoteric pursuits

many simple properties of the generalised trigonometrics
translate immediately to the tchebyshef form

take the basic rotation formula

j
g (w x) = g (x)
m 0 m m 0

now use the secret substitution and immediately

T (x) = T (x)

m n j
m w n
m

which generalises the +/- n result of classical T
due the evenness of cosinus

do you see how easy it is?

now
we can translate the general product formula as well

/ |0 n theta \ / |0 n' theta \
| | e | | | e |
\ |m / \ |m /

m-1 j
--- (n+w n') theta
1 \ |0 m
= - / | e
m --- |m
j=0

becomes

m-1
---
1 \
T (x) T (x) = - / T (x)
m n m n' m --- j
j=0 m n+w n'
m

see?

effortless fun!

of course this one generalises the classical

1 / \
T (x) T (x) = - | T (x) + T (x) |
n n' 2 \ n+n' n-n' /

so let's do something with a tiny bit more work

evaluate the indefinite integral

/
| T (x) dx
/ m n

again the same substitution

|0 theta
x = | e
|m

gives

|m-1 theta
dx = | e dtheta
|m

transforms the integral to

/ |0 n theta |m-1 theta
| | e | e dtheta
/ |m |m

now use the product rule to get

m-1 j
--- (n+w ) theta
/ / 1 \ j |m-1 m \
| | - / w | e | dtheta
/ \ m --- m |m /
j=0

m-1 j j
--- w (n+w ) theta
1 \ m |0 m
= - / ------ | e
m --- j |m
j=0 n + w
m

(plus a constant term i will ignore from here on)

change back the sub and we get

m-1 j
--- w
/ 1 \ m
| T (x) dx = - / ------ T (x)
/ m n m --- j j
j=0 n + w m n+w
m m

once again generalising a classical relation

T (x) T (x)
/ 1 / n+1 n-1 \
| T (x) dx = - | ------- - ------- |
/ n 2 \ n + 1 n - 1 /

maybe with this last example
you might begin to see how the weight function (1-x^2)^(1/2)
arises in the classical integrals of orthogonality
and how this generalises

maybe not

can you see how to represent x^n now?

we will need the representation when analysing the basis change
that underlies transforming
a taylor series to a generalised tchebyshef...

i was shocked to hear of your recent departure to the front lines

a warrior
you!

there will not be a better person killed by this senseless war
than you dear friend
i guarantee you that

..

to honor your sacrifice and satiate these penultimate hungers
i will give you the key to my challenge

but let's look at how the classical case is derived first

n / |0 theta \n / 1 / theta -theta \ \n
x = | | e | = | - | e + e | |
\ |2 / \ 2 \ / /

and
by the binomial theorem
n
---
/ theta -theta \n \ / n \ theta j -theta (n-j)
| e + e | = / | | e e
\ / --- \ j /
j=0

n
---
\ / n \ -theta (n - 2j)
= / | | e
--- \ j /
j=0

now
one can pair the +/- terms
(e^2 with e^(-2) and e^3 with e^(-3)..) so those can all be expressed as coshinusi
and if n is even
the term e^0 can be split in half
(1/2 (e^0 + e^(-0)) = e^0)
producing a coshinus even there

this is usually written

|_n/2_|
--- '
\ / n \ |0 theta (n - 2j)
/ | | 2 | e
--- \ j / |m
j=0

where the ' means that the terms are summed normally
except for the term j=n/2 when n is even
which is halved

writing this out

|_n/2_|
--- '
/ |0 theta \n \ / n \ |0 theta (n - 2j)
| 2 | e | = / | | 2 | e
\ |2 / --- \ j / |2
j=0

which
pulling out the 2s and making the secret substitution
gives

|_n/2_|
--- '
n 1-n \ / n \
x = 2 / | | T (x)
--- \ j / n-2j
j=0

so the generalisation should be obvious

since simpson's multisection formula gives

m-1 j
--- w x
|0 x 1 \ m
| e = - / e
|m m ---
j=0

one needs to calculate

m-1 j
--- w x
/ \ m \n
| / e |
\ --- /
j=0

the multinomial formula is needed

so define the collection K
as all m-tuples (k0, k1, ...) such that k0 + k1 + ... = n
and write

2
--- k0 x k1 w x k2 w x
\ / n \ m m
= / | | e e e ..
--- \ k0, k1, ... /
K
m-1
---
\ j
x / k w
--- --- j m
\ / n \ j=0
= / | | e
--- \ k0, k1, ... /
K

now
each of the m-tuples has (m-1) other rotated forms which
(by the symmetry of the mutinomial)
has the same leading coefficient

so one can group
(k0, k1, .., k(m-1))
(k1, k2, .., k0)
(k2, k3, .., k1)
together and form these generalised coshinusi

sometimes
though
these rotations do not form new terms
so one needs to split the term apart appropriately

for instance
there is only one term (1, 1, .., 1)
so this term would need to be divided by m

similarly
if m is even
(1, 0, 1, 0, .., 1, 0) produces only two different terms
so they would need to be divided by m/2

similarly if m is divisible by 3, 4, ..

this way of summing i will write as

--- o
\
/
---
o
K

where o signifies the cyclic generalisation of the ' summation
and K^o is a collection of representatives from the cyclic classes

going through the same steps above
finally gives as the solution i have taunted

--- o
n 1-n \ / n \
x = m / | | T (x)
--- \ k0, k1, .. / m-1
o ---
K m \ j
/ k w
--- j m
j=0

what a strange little formula!

this collection of representative m-tuples
forming a representative collection of points in the cyclotomic field
through a simple path sum

cyclotomic drunkards paths!

just like you used to be
dear friend

remember that one july??

i will certainly remember it

g:
> a warrior
> you!

no

i had never thought it possible
that "sometimes they trick you"

i would have thought they needed the bodies
for all those extra uniforms
flack jackets
ammunition
and primary weapons

that is certainly unfortunate
and i know your family must be severely disappointed in the whole affair

but stay strong
friend

at least they removed only inessential organs

-+-+-

you had so many questions
i wonder if my other "friends" finally got to you

if so
i apologise
but yes i can try to go back some

the goal is a fourier system

in some ways this begs i return to t (x)
m n
-m
= w g (w x)
2n m n 2n

oo
--- j
\ (-1) nj+m
= / ------- x
--- (1)
j=0 nj+m

which i abandoned long ago

the zeroes of these functions
are almost periodic like the besselian
in that

lim ( ? (r) - ? (s) ) = ?
n->oo m n+1 m n n

where m_?_n(j) is the jth zero greater than or equal to 0
of m_t_n

they all have zeroes that approach some multiple of pi in spacing

but the peaks
unlike the t_2 series
grow exponentially n > 3
and in odd-n cases
the negative domain gives exponentially dominated growth without periodicity
where the even-n of course keep the order-2 symmetry
(even/odd implies periodic in both the positive and negative domains)

a back-of-the-envelope calculation shows
using m=0, n=3 as an example

w x
( ) ( |0 6 )
Re< t (x) > = Re< | e >
( 0 3 ) ( |3 )

x '\/3 x -'\/3
- ---- i x - ----- i x
1 / 2 ( 2 ) -x 2 ( 2 ) \
= - | e Re< e > + e + e Re< e > |
3 \ ( ) ( ) /

x x
- -
1 / 2 / '\/3 \ -x 2 / -'\/3 \ \
= - | e cos| ---- x | + e + e cos| ----- x | |
3 \ \ 2 / \ 2 / /

which is zero when

x
-
-x 2 / '\/3 \
e = -2 e cos | ---- x |
\ 2 /

or

-3x
---
2 / '\/3 \
e = -2 cos | ---- x |
\ 2 /

as the exponential left hand side gets closer to y=0
it will cross the cosinus closer and closer to its own zeroes

the period of this (0,3) generalisation therefore approaches 2 pi / '\/3
(= 3.6275987...)

and this can be seen from a simple plot of this function
where 0_?_3(0) occurs at 1.8498128
then 0_?_3(j) = 5.4412334, 9.0689975, 12.696596, 16.324194, ...

so you see
a generalised fourier analysis must not use the

/
| t (r x) t (s x) dx
/ m n m' n

because roots are not integer multiples of some base periodicity

similarly
the (1,3)-t has zeroes 1_?_3(j) at
0, 3.0167442, 6.6506245, 10.278196, 13.905795, 17.533394, ...
and the (2,3)-t has 2_?_3(j) at
0 (double), 4.2332072, 7.8597929, 11.487396, 15.114995, ...

these are of course interleaved
as one would expect from rolle's theorem

these "almost symmetries"
along with the unnecessary complications of using half-periods
(so derivatives switch signs after n iterations, ie.

n
d
--- t (x) = - t (x)
n m n m n
dx

)
is one of the things that makes tchebyshef in the hyperbolics attractive

but let me show you how
my increasingly absentminded comrade at arms
you can still lay the obvious foundations


^^.

first
though
i realise i haven't told you of nausea

you know
sartre's nausea

i reread it on my recent travels to india

i tell you with full earnestness
my easily fooled one
there is no better way to read nausea
than reading nausea in india

there is this great passage
where roquentin is talking of his travels to varanasi
(then benaras)
and how we gather these experiences to sell to others
for their admiration and respect as "one with experience"

i didn't want to see the taj mahal
i swear to you i did not plan any visit through agra

it's just
i started in delhi because that's where my driver was based
and i wanted to see khajuraho
and
well
just look at a map

so my driver suggested it
for the first night's stop

#######@@@4..7*****)

the first step is to look for the paths of integration for zeroes
and since these are entire functions
all paths with real endpoints are equivalent to the real interval

the zeroes of the integrated forms are simply
(m+1)_?_n(j)
(where "m+1" takes place in Z_n)
so any interval ending on zeroes provide obvious zero periods

of course
we can slide the endpoints to any equal values of the antiderivative
but the zeroes form a "basis" of "types" of zero-valued intervals
using the equivalence class of "continuous sliding"
because each "hump" reaches an absolute magnitude greater than each

in some very important ways
these intervals
m_I_n(r,s) = [ m_?_n(r), m_?_n(s) ]
are representative elements of homotopy equivalencies

this isn't quite true in the 0_t_1 case
(e^(-x) has no zero periods - but also no zeroes)
or the m_t_2 cases
(sin/cos have peaks all 1
so "sliding" equates I(r,s) with I(r+n,s+n)
and the equivalences are represented by
m_I_2(r) = [ m_?_2(0), m_?_2(r) ])
but the definition of I(r,s) works in these cases as well
because the main point is

/
| t (x) dx = 0
/ I (r,s) m n
m+1 n

and

/
| t (x) dx in general has interesting values
/ I (r,s) m n for all p
m' n

for one reason
zeroes of m_t_n are critical points of (m+1)_t_n

so if we label these critical values

? (j) = the jth critical value of m_t_n (greater than or equal to 0)
m n

= t ( ? (j) )
m n m-1 n

then

/
| t (x) dx = ? (s) - ? (r)
/ I (r,s) m n m+1 n m+1 n
m n

example calculations for 0_t_3 give

? (j) = 1, -2.5847397, 16.055418, -98.4739, 604.01033, -3704.8236
0 3

with the basic properties of alternating sign and exponential growth

numerically, these are growing as 6.1337
but the actual value can be calculated from the formula presented earlier

one has that the leading term of the real positive part is

x
-
2 / '\/3 \
2 e cos | ---- x |
\ 2 /

and since the half-period approaches 2 pi / '\/3
the ratio of maxima is

( x + 2 pi / '\/3 )
-------------------
2
e
--------------------
x
-
2
e

pi / '\/3
= e

as one analyses these various critical values
a map of feature values begins growing

by an easy application of hermite-lindemann-weierstrass
all m_g_n are transcendental at all algebraic points
and so it is interesting to consider when these critical values are also transcendental

but that is a different direction than i want to go here

$^..~~~~~

varanasi is the oldest continuously living town in the world
over 3000 years of continuous occupation and rebuilding

it is quite an amazing discovery to learn what 3000 years smell like

waste water thrown from the upper floors of the buildings
keeping the ground wet to moisten endless piles of cow and goat shit

out of the recesses
nag champa and sandalwood mixing with something decomposing

the burning ghats blowing their occasional peoplesmoke through the narrow alleys

the stagnant and polluted ganga
controlling the winds with her schizophrenic desires

the deep black carbonsmoke of a million 2-stroke tuktuks
and sweat
and ghee
and...

thousands of years in one experience...

nnnn-v-mmmm

now
where in the fourier case one switches to
I = [ -pi, pi ] or [ 0, 2 pi ]
and brings the sin( r x ) and cos( s x ) as the scale mapping
we can generalise this procedure to the zeroes here

turning to a period agnostic form
we can arbitrarily scale all intervals to [ 0, 1 ]


/ \
? (x) = t | ( ? (s) - ? (r)) x + ? (r) |
m n m n \ m+1 n m+1 n m+1 n /
r s

now one can work only in the range I = [0, 1]
and single integrals are simple

/
| ? (x) dx
/I m n
r s

? (x)
m+1 n
/ r s \
= | ------------------- |
\ ? (s) - ? (r) /I
m+1 n m+1 n

which by design equals 0 at 1 and 0

&&&&&..&&&&

products have a lot more structure still

the products lose a strict per-zero almost-periodicity
and store information in larger scale zero patterns

for instance
multiplying 0_t_3 by 1_t_3
gives zeroes at 0, 1.8498128, 3.0167442, 5.4412334, 6.6506245, 9.0689975, 10.278196, ..
of differences approaching long, short, long, short, long, short, ..
where long = 2.4183992 = 4 pi / ( 3 '\/3 )
short = 1.2091996 = 2 pi / (3 '\/3 )
a patterned partitioning of the 2 pi / '\/3 periods of the m_t_3 family

(0,3)x(2,3) gives short, long, short long, ..
wheras (1,3)x(2,3) gives long, short, long, short again..

the same is seen in (0,4)x(1,4)
(long, short, long, short)
and (0,4)x(3,4) (short, long, short, long, ..)
but (0,4)x(2,4) is singly almost periodic of asymptotic zero period

it is easy to prove that there are integrals of these "wildly almost periodic" products
over nontrivial intervals
with value zero
(directly from its differential structure)

and so the differential structure of the critical points
(discretely) can be tied directly to the structure of integral periods

this is the whole point of fourier analysis
where integration over the periods is used to decompose into discrete sums the function transformed

but naive use of the product formula doesn't get a lot done

/
| t (x) t (x) dx
/ m n m' n

n-1
---
/ 1 \ -m' j j
= | - / w t ( ( 1 + w ) x ) dx
/ n --- n m+m' n n
j=0

n-1 -m' j
--- w
1 \ n j
= - / -------- t ( ( 1 + w ) x )
n --- j m+m'+1 n n
j=0 1 + w

the products have an interplay of the critical points
and effectively the entire zeroed-value d^m differential structure
transfered discretely across the structure of their critical points
from this ur-form of the sum of two unit cyclotomics

this is real
so it can projected term by term to reals
and summed as strange algebraics of cosines
related to the real and imaginary projections of the cycloctomics
in the straightforward way

but it becomes difficult to prove things about these expressions

some obvious symmetries suggest that
like the fundamental connection between
cosine series and the classical first tchebyshef
(the coefficients of their series are equal)
illustrating basis freedom
the differential structure could be more clearly seen in the tchebyshef language

this is why my attention has been so lately focused on the mysterious mr t
because then we map cleanly to a multiplicative composition

we don't work with the almost-periodic and wildly almost periodic structure of the critical points
we work directly in the cyclotomic rings and fields

so perhaps the simplicity would allow better characterisation
of the basis structure of a generalised analysis?

are there some collections of intervals from the I
that form more naturally complete sets than others?

understanding the tchebyshef translation would explain much of this structure

+----%,.$~~~+

the secrets are of course in some of the identities i have revealed to you
("sometimes they trick you"??? what the hell is wrong with you!?!)
but the real understanding comes in decomposing each analysis with a differential structure
and describing the transformation better
that relates the generalised fourier analysis with it's tchebyshef theory

the secret lies in the projection property of multisections
and the logical interplay of the multisection operator and the differential operator

d |m |m-1 d
-- | = | --
dx |n |n dx

quite a bit of this structure applies to more general classes of functions still
many interesting collections of hypergeometrics and their q deformations
and if i had the strength to explain tori to you
i would certainly be relieved of some of your barking

but i think that this darkening day has stolen any time for that

I had a look at the Wikipedia article on orthogonal polynomials. I
didn't know
there were so many kinds of families: Tchebycheff, Laguerre, Legendre,
Hermite
and others:

< http://en.wikipedia.org/wiki/Orthogonal_polynomials >

It seems to me you're looking for non-polynomial
non-trigonometric functions orthogonal for
the Hilbert space L^2(R, mu) , where mu is a measure on R
perhaps arising from some weight function. Maybe you've
heard of wavelets (Daubechies, others) .

below
please attempt a consistent use of

m_{/u2327}_n(j) for the jth root from zero

m_m'_{/u2354}_n{j} = jth critical value
ie. = m_t_n( m'_{/u2327}_n(j) }

and then use /u2328 as the symbol
for the interval-scaled zero period

what one eventually ends up with
after all the excruciating obfuscation is laid out
is ultimately a generalisation of polynomialness itself

orthogonality is simple

the interesting connection is that
the generalised trigonometry's orthogonality
is mirror to the orthogonality of the generalised tchebyshef

many of the classic orthogonals
including the tchebyshefs
are included in the class of jacobi polynomials

the gegenbauers are simply a subclass of jacobi
distinguished by equal upper parameters
and the tchebyshef fall in the gegenbauers
but the generalisation of tchebyshefs
falls in larger class of generalised jacobi

the trick is the switch into nonpolynomialness
through the generalised polynomial

2 n-1
w w w
n n n
y = a x + a x + a x + ... + a x
0 1 2 n-1

which
surprisingly
has some very regular zero features
but a more complex feature set

this really becomes apparent in the
generalised tchebyshef representation of x^n i posted

see

n=1 is e^x
so 1_T_n(e^x) = e^(n x)
or 1_T_n(x) is simply x^n

the taylor-mclaurin orthogonals
the most fundamental orthogs of all analysis

C 2_T_(n-1)(x) is the minimax rep of 1_T_n(x)

now there is this generalisation
and whole new set of tools for feature detection
here - more elaborate patterns in differential structure

^..^

one of the secrets hidden in the shift to tchebyshef
is the origin of the weight function

it basically arises from the presence of

|n-1 x
| e
|n

in integrals of the tchebyshefs

since in the (0,2), (1,2) case

2 2
ch x - sh x = 1

this generalises quite naturally to a function

/ |0 x |n-1 x \
f | | e , | e | = 1
\ |n |n /

where the natural question arises
is it algebraic?

the answer again is revealed in cyclotomics..

I seem to remember reading that Riemann wanted
tchebyshef to see his work on zeta and primes.
I might look up what tchebyshef did in
number theory.

Not using capital letters or punctuation is not something that
causes readability problems for me. It's OK for me.
However, formulas with exponents on the line above
don't always align well; also, towers of exponents
with no parentheses are ambiguous for me ...


So

y = a_0 x ^(n^w) + a_1 * x^(n^w) + a_2 * x^((n^w)^2) + ...

I don't think I've got it. Do you get polynomials by
setting w=1 ?

the alignment of the first exponent was my fault

the exponent terms are roots of unity
(or more generally in some of the other uses
any elements of a cyclotomic ring)

just as an example of where it comes from

ch x = 1/2 ( e^x + e^(-x) )

set y = e^x
and one has

y + 1/y = 2 ch x

turn it into a quadratic (since y=/=0 because e^x =/=0)

y^2 - 2 y ch x + 1 = 0
and use quadratic formula

y = ( 2 ch x +/- '\/(4 ch^2 x - 4) ) / 2

from the exponential (positive) nature of y
this becomes simply

y = ch x + '\/(ch^2 x - 1)

if we return back to y = e^x
then

x = ln( ch x + '\/(ch^2 x - 1) )

the classic inversion formula for hyperbolic trigs

now try to do the same thing for

|0 x
| e
|3

and you'll see where the generalisation comes in

i've mentioned these "polynomials" several times over the years
in various contexts
but one that helps visualise what these are is at

generalised polynomials have many nice properties

if f, f' e W[x]

in other words
if

---
\ w
f = / a x
--- w
w e S_f c C
n
S_f finite

and

---
\ w
f' = / b x
--- w
w e S_f' c C
n
S_f' finite

where C_n is the ring of integers
of the cyclotomic field of order n

then (f + f') e W[x]
and (f f') e W[x]

also
derivatives of e W[x]
are e W[x]

the integrals can bring in logarithmic forms
but so do simple laurent polynomials
and these are well understood

the really crazy thing
is that they seem to have an interesting zero structure
where
for instance

---
\ w
/ x = c(x)
---
n
w = 1

has n zeroes in the complex numbers

the important step
then
becomes the galois analysis

so an important consequence of this generalisation
is a whole new realm of galois study

which i am sure has already been done already
if i only knew the right keywords to search

notice that this is true
for finite subcollections that come from any semigroup

it is possible to define
<S, R>[x] as the generalised polynomial ring
with S the semigroup of exponents
and R the ring of coefficients

and these general constructs have a number of properties
more generally derivable

however
the cyclotomic generalisation has a number of special properties
that make it very natural for study

just as a quick example
even though f(x) e W[x] does not guarantee f(x)^w e W[x]
it is true that f_3(x) = x^w_3
for instance
obeys f_3(f_3(x)) = x^(w_3^2)
and f_3(f_3(f_3(x))) = x

(all this occurs on appropriate branches of course)

so this generalisation has periodic iterations possible
which are actually useful in reducing
or transforming
some expressions

these cyclotomic generalised polynomials
arise naturally in the theory of multisection
outside this focus on the multisection of exponentials
and all this work on generalised fourier analysis

in fact
in many ways the analysis can be extended beyond exponentials

the key point of all of my efforts in generalised trigonometry
was the discovery of the product and sum laws

without that
the integrals of products would have made little progress
and the tchebyshef theory would not have passed initial discovery

but a secret i've kept hidden
(mostly due to a lack of time to write it all out)
is that the technique for finding the product rule
actually works for the multisection of any function
that already has a product rule

in other words
if f(x)f(y) = g(x,y)
then we can find a product rule for

/ |m \/ |m' \
| | f(x) || | f(y) |
\ |n /\ |n /

using exactly the same steps as for trigonometrics

this is why i have always considered the generalised fourier theory
an extension of my multisection results
over all hypergeometric and q-hypergeometric functions
because much of the discussion does not reach full generality
simply at the ur-hypergeometric (the exponential)

products
the differential structure
integrals
and much of a generalised analysis
carries over to many famous hypergeometrics

and in these cases
since the product rule is derived
from simpson's multisection formula
the values at cyclotomic places comes in

in many cases of interest
this introduce W[x] again...

and you don't think your newfound desire to write sci-fi
a drive i hope you squash like the infection such desires come from
(it is laziness! a leap away from the rigors of true science!)
has anything to do with your newest suspicions
of your possible alien abduction and
subsequent
experimentation?

you don't think your fantasies influence your possibilities?

i know
you've always been the "artist"
the flighty temperamental
doesn't
always
want to consider reality

i know

but you've got it in you
you always have
and i see the seeds of potential you've grown

it will bring us some great gems if only

that theorem of yours
the five squares

you're interested you know?
you saw that one in the fractal
that series of convergence points
and all those beautiful transformations

remember?

you don't know how strong the need for recruitment is

those pacing feverish nights at the parties
you
loaded on strange experimental varieties of intoxicants
formalising various models of reality
what isness is
in realist beable ontologies
you know what i fuckin' mean

you're not fucking sci-fi

make something

it's time

@@@@$$oo%%^^^^^

sprechen über zeit
i'm sorry i take so long to write
and then only to abuse or demean
i know it seems i do not care
too much
for the exchange

but how do i exchange my time
my dear friend
when it fills so naturally with my professional duties and other kantian debris?
how can i pull new time from old?

will the greatest of desire ever defeat duty
my friend?

can time be so bent by my will?

surveying our prior exchange
i see it is time to reveal the horizontal functions

like tchebyshef
the horizontal functions are transformations
but these ones describe the origin of the weight in generalised tchebyshef transforms

please excuse my notation separating the function and it's application
but i've been under heavy influence of functional languages
of late
(it also adds notational information
since
-1
f(.) (x)
is some sheet of the inverse
and
-1
f(x)
is simply the reciprocal)

define the (m, m'; n)-th horizontal function

. .
o / |m . \ / |m' . \-1
+ (x) = | | e | | | e | (x)
m \ |n / \ |n /
m' n

notice how these are defined just like the tchebyshef are
and can even be written in the form

. .
o / |m' theta \ / |m . \
+ | | e | = | | e | (theta)
m \ |n / \ |n /
m' n

now we are converting between the various multisections

immediate consequences include

. .
o
+ (x) = x
m'
m' n

and

. . . . . .
o / o \ o
+ | + (x) | = + (x)
m \ m' / m
m' n m'' n m'' n

(over appropriate domains*)
((*inter alia über alles))

however
again
like the tchebyshef
the hidden power is masked in an underappreciated jewel of first year calculus

!! the chain rule !!

the secret lies in the differentials
(as jacobi used to scream
those late italian nights)

using the above definition
it is 101 material to derive

. .
d o / |m-1 . \/ |m' . \-1 d / |m' . \-1
-- + (x) = | | e || | e | (x) -- | | e | (x)
dx m \ |n /\ |n / dx \ |n /
m' n

and so reduces to the calculation of the derivative of the inverse

but the derivative of the inverse is easily given by

/ |m . \-1
y = | | e | (x)
\ |n /

/ |m . \
| | e | (y) = x
\ |n /

so

/ |m-1 . \ dy
| | e | (y) -- = 1
\ |n / dx

or

dy 1 1
-- = --------------- = --------------------------
dx / |m-1 . \ / |m-1 . \/ |m . \-1
| | e | (y) | | e || | e | (x)
\ |n / \ |n /\ |n /


1
= ---------
. .
o
+ (x)
m-1
m n

plugging back in the original differentiation for the horizontals


. .
o
+ (x)
. . m-1
d o m' n
-- + (x) = ---------
dx m . .
m' n o
+ (x)
m'-1
m' n


look how pretty she is!

for n=2
this theory is the classical


. .
d o x
-- + (x) = ---------
dx 0 . .
1 2 o
+ (x)
0
1 2

. .
d o x
-- + (x) = ---------
dx 1 . .
0 2 o
+ (x)
1
0 2


the general solution for these is y = ( x + C )^(1/2)

using y(0) = 1 for (0,1;2)
and y(1) = 0 for (1,0;2)
gives the classical results

. .
o 2 1/2
+ (x) = ( x + 1 )
0
1 2

. .
o 2 1/2
+ (x) = ( x - 1 )
1
0 2

the properties above can all be verified
including the interesting iterative properties

but i can't go on

i have far too many other tasks to complete this night
and far too little desire to waste my time
describing what you yourself can derive quite easily

can you extract these hors?
can you give them expression?

maybe you can start with n = 3?
or are you completely lost to a life of convenience?

for that map you mentioned
this was all derived on the drive from delhi to agra
that first day of the vacation up north

after the bengalurian insights
i wanted badly to check these trasformations
but became
as now
so loaded in the mud of other people's privilege
that it was not until the vacation that i could approach
their tender glassblown jaws

remember
you too used to get it

that unmentionable gnosis
those words and the symbols scrawled

you know

the creation and the materialisation

when dreams could become realities experienced
touchables

that's what you need to be doing

i walked back up front and sat in your stone garden

you have that shaded bench in the corner

the postman passed by and almost didn't stop

i know you
though
and i know you have abused mailorder
and have daily shipments with hundreds of catalogs of empty amusements

i know the trash you generate

no trash?
no mail?

so i stopped the postman and asked why you had no mail
and how long you hadn't
and i told him i was very freaked out
and

he said he wasn't allowed to tell me much
that really he couldn't tell me anything
but
he could see i was concerned
and it was strange that your mail had stopped

he said he had looked into it
and found you had forwarded your mail

but he couldn't tell me where

i was very confused and really tried to get him to tell me more
but he told that they couldn't tell people things like that...

...because i might be a stalker!

he said i seemed pretty nice
but i _was_ waiting around his house
and i _was_ asking his postman about his mail
and that
just on odds
they had strict rules at the post office about confidentiality

they reveal themselves in concepts

i keep going over the multisection-generated generalisations
and the cyclotomics pull me deep inside this cavern of crystalised patterns
gems and jewels along the walls like some fine museum
yet grown naturally
in the belly of natural relations
still digesting

why does this fascinate me so?

the infinite generalised fourier theory
which though certainly simpler
looking back on my notes
i have not really mentioned to you

look at the way derivatives behave
with these infinite interval transforms

first
the functions in this theory
are all O(e^(-ax)) as -> +/-oo
for certain 'a' that depend on n

now

/ oo
F [f'; k] = | f'(x) t (kx) dx
m n / -oo m n

can be rewritten using the chain rule as


/ \ oo / oo *
| f(x) t (kx) | - k | f(x) t (kx)
\ m n /-oo /-oo m-1 n


where t^* is t except when m-1 = -1 = n-1 (by modular arithmetic in m terms)
where it is -t

this is simply

*
(- k) F [f; k]
m-1 n

so taking a (m-1, n)-transform and multiplying by (-k)
is equivalent here the (m,n)-transform of the derivative

of course
all this *-complication is removed if we just look at the transforms by G
(the hyperbolic generalised trigonometrics m_g_n)
and this does not change the requirements on the function space that can be transformed
(which is why i so much prefer the hyperbolic theory)

but this is the obvious generalisation
of the classical infinite fourier theory
which encodes this differential theory in multiplication

these are the types of relations
that build a transform theory

addition <------> addition
multiplication <------> differentiation
differentiation <------> multiplication

similarly
through what i call the "ultramodulation of generalised trigonometrics"
there is a generalisation of the shift-operator
which again looks nicer in hyperbolic form:

L[ t (k0 x) f(x); k]
m n
||
||
n-1 j
/ oo k x --- w k0 x
| f(x) t (k0 x) e dx = / oo 1 \ -m j n k x
/-oo m n | - / f(x) w e e dx
/-oo n --- n
j=0

//
//
n-1 j
1 --- (k + k0 w ) x
- \ -m j / oo n
n / w | f(x) e
--- n /-oo
j=0

\\
\\
\\


n-1
1 ---
- \ -m j j
n / w L[f; k + k0 w ]
--- n n
j=0

where L is the two-sided laplacian transform
(which the 1st level generalised hyperbolic infinite interval transform is)

similarly

n-1
---
k0 x 1 \ -m j j
F [e f(x); k] = - / w L[f; k0 + k w ]
m n n --- n n
j=0

and in general
a lot of the dance in the classic theory
between laplace and fourier transforms
plays out in this general form


it's always the same

made themselves apparent in the world around me
in the array of my cd shelf
and the flower arrangement in an indian rug on the wall
and i could see the use in the delicate manipulations
in many logical deductions

or maybe i'm not really thinking of that at all
it's more like i'm thinking about
the way the addition rule for generalised trigonometrics
picks out certain projections and automorphisms in the cyclotomics

as i've shown you many times
the addition theorems arise from the product
through simple linear inversion

i can build the table of products

1 / 2 \
t (a) t (b) = - | t (a + b) + t (a + w b) + t (a + w b) |
0 3 0 3 3 \ 0 3 0 3 3 0 3 3 /

1 / 2 2 \
t (a) t (b) = - | t (a + b) + w t (a + w b) + w t (a + w b) |
1 3 2 3 3 \ 0 3 3 0 3 3 3 0 3 3 /

1 / 2 2 \
t (a) t (b) = - | t (a + b) + w t (a + w b) + w t (a + w b) |
0 3 0 3 3 \ 0 3 3 0 3 3 3 0 3 3 /

------------------------------------------------------------------------- 2
using 1 + w + w = 0
3 3
so that t (a) t (b) + t (a) t (b) + t (a) t (b) = t (a + b)
0 3 0 3 1 3 2 3 2 3 1 3 0 3

and if i look at some cyclotomic sums (times an x for placeholding)
j j j j
t ((1 + w ) x) = t (x) t (w x) + t (x) t (w x) + t (x) t (w x)
0 3 3 0 3 0 3 3 1 3 2 3 3 2 3 1 3 3

2j j
= t (x) t (x) + w t (x) t (x) + w t (x) t (x)
0 3 0 3 3 1 3 2 3 3 1 3 2 3

/ \2 / 2j j \
= | t (x) | + | w + w | t (x) t (x)
\ 0 3 / \ 3 3 / 1 3 2 3

and then i insist i am misunderstanding the "natural" interpretation
that this really is more natural in the language
of the genus of a multiplicative series
and i think longingly on the witten genus..

and
that's what i'm like
these days

everything
is
in
pattern


i am
breaking i am
apart dissolving

no i


i was walking through the parking lot
of a local marketplace
the other day
when the lines of vehicles fell
in the classic vanishing point of theory
upon the doors of the store

and i saw in their mouth all of a sudden
that the building was hungry yet devoured many customers
an insatiable hunger which a mild tranquilizer
helped all ignore as they entered the jaws
a soporific muzak to deaden the leeching
like the spit of vampire bats

i ran from the store

i saw the datura
i actually saw it
in india
in a tenth century temple

!!!a datura in a _tenth_ century carving!!!

it was in some pictures of durga i took
i didn't see it until the other day
but it was right there in right hand by her head

all these patterns keep flying out

here are some of the pictures

and the tchebyshef

they keep guiding me to these finite forms

/ /u0917x(3, n)
a = | g(theta) g (k theta) dtheta
k / 0 0 n

where g(theta) = f( g (theta)) or set x = g (theta)

here theta = g (.) (x) and dx = g (theta) dtheta

then a = - | ----------- dx

this is the fundamental relationship
between fourier series and tchebyshef series
generalised to this cyclotomic chaostrophy that now envelops me


you know that song

i fight with myself more often these days

you know
those transformation of bases
where x^i ---> (f(x))^i
can be mapped
inherit all that structure
of the classic pfaff and euler transforms
and any of the thousands of related transformulae
..................

???????????????????????????


did you ever see the little trick
to find the differential equation for the horizontal functions?

you form the equations with the upper term x

and convert the lower term by repeated differentiation back to the main form
it's basically a substitution exercise

you get a n-th order nonlinear differential equation
for the horizontal functions of order n

fortunately
this is not impenetrable

starting with order 3 shows the way pretty well

^..^


i drank a little the other day
just to kill my brain a little
just for a brief night's rest
but i awoke early the next morning
and could no longer keep away the patterns

i was even more off and edgy
odd
if you insist

i don't even have drink as a refuge

is this how they took you?

i don't understand the forwarding?

it all makes so much sense
that in the end it makes no sense at all

all the connections and none of them at all


@#@##@$#@#$@#@#$#$#@$@#$@#$@#$@

remember when i pointed out the connections between post logics and multisections?
how the various function spaces generated
could interpret the negation in differentiation
and how the various multisections could play the roles of truth values?

maybe a curiosity
but
recently i saw a paper on the galois theory of post algebras
and these strange obsessions began to take hold
sheaf theoretical interpretations appeared as dancing symbols before my eyes

i think i finally see
how these multisection projection logics
peer into the geometry of the functions they act upon

the geometry of the circle
the exponential
is only the first stage

and after thinking these thoughts in the dumbstruck awe of discovery
after seeing these relationships so clear and tangible
i looked down and saw i had drawn this scene

http://galathaea.org/facesInStone/DSC04944.JPG

this was not the first
i have found pictures drawn after several of my disturbances

http://galathaea.org/facesInStone/DSC04945.JPG
http://galathaea.org/facesInStone/DSC04946.JPG

this is not good
remember crumb's brother charles?

i am very scared about all this

ooooooooooo
ooooooooooooooooooo oooooo
oooooooooooooooooooooooooooooooooooooooooo
ooooooooooooooooooooooooooooooooooooooooooo
ooooooooooooooooooooooooooooooooooooooooo
ooooooooooooooooooooooooooooooooooo
oooooooooooooo ooooooo


i awoke the other day with a sharp pain in my back

there were two sharp peaks protruding from my scapulae
slightly curved out
as if to follow the scroll of my spine

the skin was pulled taught around them
and the area was very sore

every time i touch them
even slightly
my eyes glaze over and the room seems to crystallise in millions of facets
leaving a headache that lasts for hours

i am going to see a doctor about it today
i can no longer wear a bra

this is not acceptable

the narrator is clearly disturbed
and the threads of valid deduction are fraying

but
there is still a whole process that must unfold

there won't be reconciliation until all the ghosts have gone
and that means destroying a lot of dreams

although there is great hope and drama
ultimately things will end up mostly tragic

wait until the subtly hidden arithmetical flaw
reveals that none of this math is valid?
or watch as awkward claims of meaning
slip away with scrutiny?

how badly will it end?

guidance can only come deus ex machina

D'oh! I think that goes some way to explaining why, when I tried
to watch "Faraway, So Close!" (or rather, in keeping with the title
of this thread, "In weiter Ferne, so nah!"), I couldn't get into it!

it broke like the hand of a china doll

a shatter in my palm
muffled and piercing
my flesh

my


doorway adorned itself in elaborate display half-wound with
the winding storm-ridden worm-eaten half-rotten willow
peel bark wrapped
and woven around
the frame hollow
and

though
there was always
debate it could be
paper-thin hate-filled
strands of darkness
there was confidence
it spied on me in the late

with


pin-point

eyes


i have not slept in days

outside is no longer the isworld
it is an almostworld
a shifted world


outside
the skeleton of buildings lay criss-crossed
as if shifted in some great cataclysmic
twisting of the earth
a bending of fortunes
weaving the steel skeletons
crashed together
$#%#%@%$#%@$%@
people too
were shifted and
scarred * a brutal few
themselves skeletal
and caricature
$%$#%%#$@$# %$#@$%@$%@#$
and etched post-nuclear
the signs the signs

the vision of varanasi


which i had so celebrated as the first nontrivial property of W [x]
n ow haunts me
in this brutal landscape
to the accompany of earth rumbles
and the crashes of distant wars

i don't know what i have become

there is an anger in me
growing

with the tusks


what had begun as two strange growths
has over these few weeks become
four then eight
then ten and
twelve
and
more


bone had thrust from ugly wounds
in these long tusk-like spears
one row along the upper plate of my back arched downward
and one just below the small of back where my pelvis spreads
arched towards the sky


the wounds had seeped for days

when i must leave
and i have found ways to limit this to less than once a week
i have nothing i can wear to fit my new form
so i have learned to wrap some indian silk around my top and middle
biting back the pain


i hate the ugliness of this monster i have become
i hate
i hate

and her bitterest voice i obsessively recall


"and all the baby boys we've born
with eyes averted from the storm
SENT OFF TO DIE IN PERFECT FORM
WE KNOW NOT NOW WHAT WE HAVE KNOWN

satellite photos and rhetoric
see how the euphemisms stick
AND WHEN THEY COME BACK BROKE AND BURNED
THOSE WHO'VE RETURNED HAVE NOT RETURNED.."


i keep going over the same things


i can't take it anymore
i just spend hours crying and screaming
my back
my mind
my world

the brothers are patrolling the streets now

first it was the genes
and now the brothers have jumped in

everyone's looking for a piece of control

as always happens once the market's saturated
the exploitation of paranoia has begun

security and paranoia in this millennia-old interplay
where
there really are a lot of exploits
and it really does require attention to every minor detail
and just because you're paranoid
doesn't mean they're not out to get you


and it looks so foolish

i figured it out the other day
it's so obvious and silly

i'm not rational anymore
i'm transcendental
i'm beyond algebraic
i'm allegoric

i actually saw it graffitied to some buildings

and i was a module at the birth of time

an actor acting upon the state of things
when the main actors realised themselves

it was always about control

nature had developed decision points
subsystems of sufficient complexity
to process information input
and compute response outputs
according to some algorithm of drives

purposes

and the input
it's symbology and learned metaphors
were the primary point of control

technology
as a physical process in the universe
began to see itself


like i now saw myself
in the mirror of the door

hideous and fierce

what did these symbols mean?
why do they haunt me?


take the number e and try to build a ring out of it by generation
(in R if it helps)

it will have 0 and 1

n
it will have e for all n >= 0

most fundamentally
every member of this generated set could be expressed in the form


---
\ j
/ a e where a elementOf Z
--- j j
j elementOf J
J subcollectionOf N (n >= 0)
J finite


this ring of transcendental numbers has the same presentation as Z[x]
once one makes the identification e -> x

of course this can be done with any free generator (Z is universal here)
and so any transcendental has the same relationship
but there is an even more fundamental relation between exponentials
that comes into play once inversion is considered

x
the map e --> x can be inverted on a sheet through the x --> ln(x) mapping
it's use here is trivial
but it will become obvious later how the generalisations take advantage of this structure

fundamentally here
the structure of certain rings generated by transcendentals
can be derived from the isostructure in rings generated by unknowns

but this is all so much local structure
it is important to take a step back and see what has been wrought

x x
the fixpoint relation D e = e
x y x+y
and the product formula e e = e n
interact through this fundamental connection of the power maps x -> x
viewed as an injective ring homomorphism
and the fourier interpretation of these as a transform

starting with the differential structure
2
the taylor expansion of the exponential as 1 + x + 1/2 x + ...

n n-1 n-1
/ x \ / n x \ / x \
and in particular how D | ---- | = | ------ | = | ------ |
\ (1) / \ (1) / \ (1) /
n n n-1

gives the fundamental relationship behind the exponential
the factorial
the differential
and neighboring indices in the taylor basis

and is what structures the entire theory

the transform provides the interpretation of exponential map as shift operator
exposing it's group theoretical structure on tangent bundles of the euclidean manifold


now the bisection gives instead

differential structure-----/

and here the classic connections really show off the algebraic structure


the product formula become
ch(a) ch(b) = 1/2(ch(a + b) + ch(a - b))
ch(a) sh(b) = 1/2(sh(a + b) - sh(a - b))
sh(a) sh(b) = 1/2(ch(a + b) - ch(a - b))
and the matrix interpretation appears as the inversion problem gets investigated

the first sum formula ch(a + b) is accomplished
by listing the product combinations that give order 0 (ch) terms
(these are (0,0) and (1,1) - ie. ch(a) ch(b) and sh(a) sh(b))

one must then invert the matrix
| 1/2 1/2 |
| 1/2 -1/2 | a humble little thing

similarly
the differential structure begins to reveal a little of it's algebraic form

by the twisting property of the differential here
D ch(x) = sh(x)
D sh(x) = ch(x)

the system may be given a matrix form

| ch(x) sh(x) | | 0 1 | | ch(x) sh(x) |
D | sh(x) ch(x) | = | 1 0 | | sh(x) ch(x) |

where the matrix | 0 1 |
| 1 0 | is a lot like -1 in that

| 0 1 | | 0 1 | | 1 0 |
| 1 0 | | 1 0 | = | 0 1 |

-1
the classical tchebyshef give the operators over Z[x, x ]

/ 1 / -1 \\ 1 / n -n \
T | - | x + x || = - | x + x |
n \ 2 \ // 2 \ /

a beautiful little interpretation of power maps in the land of laurent

but laurent polynomials are in some sense a trivial extension of Z[x]
since every laurent polynomial may be factored as

m k+m
--- ---
\ j -k \ j
/ a x = x / a x
--- j --- j-k
j=-k j=0

and so one does not get any interesting extensions of the algebraic numbers

also
if i go the other way
it is easy to form an inverse polynomial
and get factors in terms of inverse monomial differences

-1
e.g. (x - z) ---> x (1 - z x )

and so Z[x, x^(-1)] fails to have unique factorisation
(and all x^j have become units)

even still
generalising the operation of algebraic extension
still works in the obvious way here
as long as one still chooses the appropriate definition of irreducible


(there was this hallucination i had the other day
where the door was playing mirror and i was looking at myself
and this inner view emerged enlarged yet simple
and i saw the simple way my properties fit
in algebraic connectives that formed the logic of my description

i was no longer angry at myself

and i finally saw what factors were at play

as the hallucination faded
the doorway told me in it's whisper
"inner factorial rings"

the books tell me it is something important here)


inversion works for the trigonometrics
and displays why the trivial inversion for exponential becomes important

-1
1 / -1 \ x / 2 \
- | x + x | = a ~~~> - | x - 2ax + 1 | = 0
2 \ / 2 \ /

and the extension to the splitting field gives

2 1/2
2a +/- (4a - 4)
x = -------------------
2

x
and since this is based on the substitution x ~~> e
x is positive which selects

2 1/2
x = a + (a - 1) when a is greater than 1

mapping back the translation gives

-1 / 2 1/2 \
ch(.) (a) = ln | a + (a - 1) |
\ /

this illustrates the essential connection between extensions of these laurent polynomials
and the inversion problem for trigonometry

generalising over all multisections gives

and here
with n=3
we get the first nontrivial extension of algebraic numbers


W [x] is twisted in a macabre way
3 and the tchebyshef are no longer polynomial


2
w w
3 3
here x x x = 1

2
but the rays n, n w , and n w no longer contain all exponents (like 1 + w )
3 3 3

in fact
from any two neighboring rays in a finite set of rays
one can always find two elements that sum to an element not on any of the rays
so
although on any ray things behave much like Z[x]
once terms can be across rays
products produce many new symmetries of terms

and now
monomial differences are no longer sufficient to factor

w
3
x + x + c has no such factorisation

it becomes important to study deeper the level structure
where a cyclotomic integer is of level n
if it is expressible as

2
j + j w + j w with j + j + j = n
0 1 3 2 3 0 1 2

since the collapsing of levels is what defines
how the structure of these types of irreducibles is much enhanced over Z[x] here


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~>..<~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~*


as with the case for producing the algebraic numbers
one forms the collection

I = { (p) | p irreducible in W [x] }
3

and takes the direct limit


A = lim W [x] / (p)
3 --> 3
(p) e I

which is strictly larger than A
the field of algebraic numbers


similarly
the galois group

---
|
| (A / Q)
3 Q 3

is the projective limit

/ / \ \
lim gal | | W [x] / (p) | / Q |
<-- \ \ 3 / /
(p) e I


it is strange how much of the classical algebraic theory comes over
in these new generalisations which contain some strictly transcendental elements

much care must be taken to ensure that these are meaningful operations
but once one overcomes W_23
one can consider even more grand constructions


one can consider lim A as some generalised algebraic field (which is still not C)

it is like he told me in his "reapings and sowings"
about opening the nut with a hammer and chisel

" I can illustrate the second approach with the same image of a

immersing the nut in some softening liquid, and why not simply
water? From time to time you rub so the liquid penetrates better,
and otherwise you let time pass. The shell becomes more flexible
through weeks and months—when the time is ripe, hand pressure
is enough, the shell opens like a perfectly ripened avocado!
A different image came to me a few weeks ago. The unknown
thing to be known appeared to me as some stretch of earth or
hard marl, resisting penetration. . . the sea advances insensibly in
silence, nothing seems to happen, nothing moves, the water is so
far off you hardly hear it. . . yet it finally surrounds the resistant
substance. "


whatever is dissolving me is toxic
an organic solvent intoxicating through brain damage


i have to face the outside again

i have to find answers to questions i do not know how to ask

these tusks
these jaws of malformed bone protruding from my back
are growing restless


i have to leave

i have to go outside the door

I enjoyed reading what I was able to understand of this. I'm unable to
judge whether it's a good experimental poem aimed at a limited
audience or pretentious crap; but even if it's pretentious crap it's
the kind of pretentious crap I enjoy reading. :-)

Thanks for posting. What does "봄의 끝" mean?

definitely it is pretentious

i'm too much of a narcissist for it to be reserved
(and the latin praetendere fit's my sig perfectly
despite it's unfortunate lack of presence in the former post)

when i get to pointing out
that the differential structure generalises easily
and for hypergeometrics we get

n
(xD + b1 - 1)(xD + b2 - 1)...(xD + bq - 1) CH (..) =
p q
n
(xD + a1)(xD + a2)...(xD + ap) W CH (..)
n p q

n
where CH is the n-multisected circulant matrix

| |0 |1 |n-1 |
| |n H |n H .. |n H |
| p q p q p q |
| |
| |n-1 |0 |n-2 |
| |n H |n H .. |n H |
| p q p q p q |
| |
| . . . . |
| . . . . |
| |1 |2 |0 |
| |n H |n H .. |n H |
| p q p q p q |

and W is the n-dimensional matrix root of unity
n

| 0 1 0 0 0 ... 0 |
| 0 0 1 0 0 ... 0 |
| 0 0 0 1 0 ... 0 |
| . . . . . .. . |
| . . . . . . . . |
| 0 0 0 0 0 ... 1 |
| 1 0 0 0 0 ... 0 |

you may see the pretension really start to kick in
as i start making huge claims about the differential structure

and once i point out the connection
between the horizontal functions
and the splitting fields
i may start playing like i've created
the second coming of modular functions!

it was the end of every living dream

a vast emptiness
despite so overfull of decay and the destroyed

colorless stretches of concrete
blacktop
and rubble without stain

a landscape sterilised by rivers of oil and distillates
cleansed by a greyish-white dessicating film

there was no life
or at least anything that would be proud of such a title

i stood there in the daylight glow and stared out
just outside the room i had hidden in so long
and out in the wasteland
under the brilliant poison sky

i realised that it was all my fault

what ever has happened
whether my brain has fried and none of this is real
or some insanity has warped the laws of the world

this is my fault

that much is perfectly clear


if reality has changed
it is related in some way to that day i went to your property

the day i trespassed

and if my mind is screwed
the fault should be clear


i am so stupid sometimes

and now i have really fucked things up

sometime shortly after stepping outside
i began to recall a story i had been writing
but many years ago abandoned

it was called:
q-"which way" tales
and was a collection of small fables
of strangely deformed generalised trigonometrics

they were daily tales
hard-struggle americana frontier tales

grandmother q-exp had many faces

she was an unstable witch
who alternately was always the most stable for us
in these twisted-deformed worlds

she was our stability in the primordial differential structure

the q-worlds had a strangely bent accounting
with a skewed and twisted form for numerosity

a q-number began with [n]
q
some function of q that had a limit as q -> 1
of n
associated to this arithmetic
was a q-differential
which could be defined linearly on the basis power elements

n n-1
D x = [n] x
q q


the deformations had many forms
which seemed to be due the slippery nature of [n]
q

the fundamental deformer

the left-hand (sinister) form
described
n
2 n-1 1 - q
[n] as 1 + q + q + ... + q = ------
q 1 - q

which has a nice geometric summability

the middle path deformer speaks of

n -n
q - q
[n] = --------
q -1
q - q

the sinisteria believed the q-derivative
could be defined as

f(q x) - f(x)
D f(x) = -------------
q (q - 1) x

to give them the formula on the basis elements

the middlers expected the symmetry to obtain through

-1
f(q x) - f(q x)
D f(x) = -----------------
q -1
(q - q ) x

in every world
grandmother q-exp was the one where

D exp (x) = exp (x)
q q q

strange grandmother q-exp had many other forms
and at one time
us children put together a scrapbook of her faces
which included the strange tales of

n-1 j
--- w n
\ (n-1) j n
/ w q
--- n
j=0
[a] = ---------------------
n q n-1 j
--- w
\ (n-1) j n
/ w q
--- n
j=0

the great hydra grandmother


but of the many tales
and of their many contradictory paths

we always knew her as D exp (x) = exp (x)
q q q

and on the power basis she was always

oo
---
\ 1 j
/ ------- x
--- (1; q)
j=0 j

j-1
---
where the (a; q) = | | [a + k]
j | | q
k=0

are the source of the janus affliction

when we were very young
we all were very excited to hear
the great tale of how grandmother learned of her noncommutativity

she was producing

producing
we had learned
was grandmother's meditative way of relating distant parts of herself
by taking their product
producing some whole new part of herself to learn from

and in her playful afternoon
she came to understand that her product rule was not guaranteed

or at least
it didn't quite work out right commutatively
as she turned her symbols around in strange combinations

the product formula for q-exp works out as

oo oo oo oo
--- j --- k --- --- j k
/ \ a \ / \ b \ \ \ a b
exp (a) exp (b) = | / ------- | | / ------- | = / / ---------------
q q \ --- (1; q) / \ --- (1; q) / --- --- (1; q) (1; q)
j=0 j k=0 k j=0 k=0 j k


oo n
--- --- j n-j
\ \ a b
= / / -----------------
--- --- (1; q) (1; q)
n=0 j=0 j n-j

now

n
--- (1; q)
n \ n j n-j
(a + b) is not in general equal / ----------------- a b
--- (1; q) (1; q)
j=0 j n-j

which works for the classical binomial
but which deforms in this strange world

so her product rule
which she knew and used from as a child
does not seem to work out

,.


it was only many years later she learned
that this was all the fault of my itty bitty deformity
and ultimately me

but meditating upon these symbolic forms
grandmother in her brilliance learned
that there was a step that could be accounted
assuming a controlled break commutativity

if this were a noncommutative ring
the level of noncommutativity could be used to accommodate the deformation

grandmother q-exp found her noncommutative ratio q

if ab = q ba
thought grandma
then things work out

this can be seen by looking at the iterative step
of multiplying by (a + b)

n+1
--- (1; q)
\ n+1 j n+1-j
/ ------------------- a b =
--- (1; q) (1; q)
j=0 j n+1-j

n
--- (1; q)
n+1 n \ n j n-j
= (a + b) = (a + b) (a + b) = / ----------------- a b (a + b)
--- (1; q) (1; q)
j=0 j n-j

and so the rule gives the law on the deformed binomial coefficients
by equating like (j, k)-power tuples

(1; q) (1; q) (1; q)
n+1 n-m n n
-------------------- = q --------------------- + -----------------
(1; q) (1; q) (1; q) (1; q) (1; q) (1; q)
m n+1-m m-1 n+1-m m n-m

and doing the multiplication on the other side gives the law

(1; q) (1; q) (1; q)
n+1 n m n
-------------------- = --------------------- + q -----------------
(1; q) (1; q) (1; q) (1; q) (1; q) (1; q)
m n+1-m m-1 n+1-m m n-m

using both of these equations
a single component recursion can be derived
which illustrates why some deformations are more relevant to these product rule concerns


..


we never knew exactly how grandma had made the leap


it often seemed backwards to us growing up
that she had found the rule to the q-deformed choosers
somehow through the noncommutativity insight
and we often suspected she had worked long in her self-analysis
but when we asked
and we asked with the hunger of childhood
she would just smile at us
with that sparkle of something mischievous
glinting off the many facets of her eyes

later stories of grandmother q-exp always seemed to go into these strange deformation algebras
but there were more subtle dependencies on deformation type
defining the allowable forms

the left-hand and middle paths were dominant players
though there were also squeezed (q^(1/2) - q^(-1/2)) grandmothers and other exotics
who played important roles in many tales


^^


the product rule issue had other generalised forms outside the noncommutative realm

commutatively
the product could be of two related forms
as
for instance
the sinisteria do with their

[n]
* q
define [n] = ----
q n
q

and q-exp* the associated fixpoint of the differentials


then there are a number of product-like rules that can be derived
through relations of these across various bases

i remembered that these sections on commutative symmetry relations
were long and tedious sections
enumerating the intimate connections
and improper familial relations
of the commutative family
but it was acceptable
in fact proper
for americana to have long sections of tediousness

because all life was tedious
and true americana glorified this work ethic
entranced in the vision of the next generation


$$&%#(%(_#@&$%$
^^ ^^^


which is why the q-"which way" tales turned to the next generation

they were the first loved
the second generation
grandmother's own ch and sh
q q

ch was born first
q

when in a flash of productive insight
grandmother q-exp bisected her infinite form
projecting half her essence to a completely new entity

---
\ 1 j
/ ------- x
--- (1; q)
j in 0 (mod 2) j

grandmother said she chose the name
because she had never liked the q in front on her name
and wanted a name that didn't bring the back of the throat forward
like x being followed by p
instead preferring the upfront and more muted voiceless postalveolar affricate ch
followed with the voiceless uvular plosive stop q

in the process of this projection
grandmother q-exp exposed a second child
who was born a moment later
and quickly named sh because she was crying
q

---
\ 1 j
/ ------- x
--- (1; q)
j in 1 (mod 2) j

ch and sh were very precocious children
q q
but grandmother q-exp grew concerned and frustrated as she prepared their lessons

she wanted to teach them early of producing
because it had been so important to her own growth and education
but she found they didn't have her product law

the q-which way tales included seven stories at this point
collectively known as the septic tales
where grandmother q-exp travelled to the great library
and found reason in the books of the ancients
to pursue seven quests for deeper knowledge

it was in the fifth of these quests
after the great conflagration
and the slaying of the demon mahakazam
that grandmother first gained access to the ancient trigonometry
and found the classic product rules

ch(x) ch(y) = 1/2 (ch(x + y) + ch(x - y))
ch(x) sh(y) = 1/2 (sh(x + y) - sh(x - y))
sh(x) sh(y) = 1/2 (ch(x + y) - ch(x - y))

and
as a part of her revealed enlightenment
she was finally allowed to understand the myth of the undeformed
the ideal of an emanation
upon which truth may be revealed

for these trigonometrics were built using an ideal exp called simply e
that part of grandmother q-exp she had learned to hide
having grown a thick skin in the reality of the deformation

x -x
ch(x) = 1/2(e + e )

x -x
sh(x) = 1/2(e - e )

grandmother q-exp told us that she understood these equations immediately
having __felt__ them so intimately when her own children were born

it was a place of much comfort and understanding to wise grandmother
and she immediately recognised that products were not a problem

it was her noncommutativity trick again
and it worked exactly the same
and she immediately realised it

the process itself
the projection
carried over all the properties
from the base q-exp to her offspring

all of it worked out perfectly in the way she was so familiar:
ab = qba

this was secretly related
grandma had learned through deep study
to not existing as functions in some space
but instead as operators over those functions

just as she was the deformed orbit generator
they were deformed operator trigonometries


much much later
in the seventh of her quests
where ultimately she learned the secret of the deformation
she found along the way a copy of a strange text
of the curious title "industrial metempsychosis"
which in it's earliest chapters described
a trigonometry of even greater greater generality

this was long after me and my two sisters had been born
and too late to have helped explain our early chidhood confusions at our origins
and the lingering stain that our birth may have been
brought about the great midlife crisis of sh
q
and deep traumas of her independence and self worth

mother sh had had many problems
q
in the face of having no productive forms independent of ch
q
and had long and great battle with chemical dependency
that may have brought about the era of twisting
which had eventually split us into existence
hungry and cold
waiting for the onslaught of winter
over the isolated prairie plains

at least
that was the way the tales told the stories
in their melodrama and opera
particularly in the parts that were driest
and failed to develop the characters sufficiently

this was the part of the story
where i introduced the deformed generalised trigonometry
and its q-fourier theory
and there was not much new from the classic theory
since the product structure on which it was built had not changed
save for the radical switch to the noncommutative realm
in which all us offspring grew

the story of the q-tchebyshef's was precisely the same

the symmetry was solid from that point out

the story from there dissolved in the afternoon winds

i felt my skin dry in the solving sterile breeze
the skin crack and brittle in the spray


it was time to find a way away

there was a road away from my place
but it was not the road that had been there before my seclusion

it was transformed
mutant
cracked through some acceleration of aging
and twisted through strange upheavals


neighbors' houses were abandoned
or at least i hoped them abandoned

in their silence and ruin


i really wasn't speaking to myself much
i was walking
and fearing
and slowly sickening

it was blacktop
soft
almost rivers under the bleak white directionless heat of the day


**********************


as the afternoon latened and darkled itself back into my attention
i was startled at the sound of someone screaming down the road

it wasn't the frightened kind of screaming
that had secretly been drowning my thoughts since i left
but it was more that laughing form of sports bravado
that plunders sunday afternoons with various intoxicated outbursts


i could see him about a kilometer off
and he probably first saw me at half that


it was hard to see what he was doing at first
he was so far off
and the haze and smoke obscured him to a shadowy silhouette


.


it was then that my observer
my analyser
got through


it was then that i heard that almost silent screaming
" YOU HAVE NOTHING!! "
" YOU HAVE NO PROTECTION!!! "

enter into focus

i had no protection
i hadn't even taken a knife when i left
i've just been stumbling forward in some kind of daydream

waiting for inevitability


i know there is something really wrong with me
still it happens almost as an afterimage
the progressions of patterns found in patterns found in patterns in my view

every higher order breakdown fractured by
something blurred
distorted
almost forgotten

and realising this might cost me my life
scared out an island of sanity for the observer to take over


^..^

as i came closer to this screaming and swaying amorphosity
i slowly pieced together the major features

- the top of this form was fast moving and the source of the sounds
- the bottom swayed in slow and stumbling rhythms

i began to sense more clearly the structure of the forms present

- the top had an extremity waving wildly above it
- as a voice more and more clearly screamed:

" yeah!!!....
...come on boy!!...

...give me another strip of that chest meat!!...

....don't give up on me now!!...

..watch the fucking curb!! i don't want you dropping me...
..again!... "


i stepped forward
still enraptured in my inevitabilities
but cautious as i waited for the full revealing

- the bottom form
looking ever more like a person through the haze
was also making noises
issuing gruntings and high pitched wheezings erratically

- the top form soon revealed itself also very human looking
apparently riding upon the shoulders of the unfortunate lower one

the scene was becoming clear

they saw me

"hey there missy" said the man on top
drunkenly shifting in his lovecraftian cowboy fashion
tan galan hat in his left hand
animated

i stood there tense
in perfect readiness

"don't worry missy"
"i ain't got no need to eat ya here with spit around"
he laughed and ripped an ear off his unfortunate companion
on whose shoulders he was riding

spit was the walking dead
a skeletal frame around which
bruised and shredded muscle
wound
in strands of tenuous connection
a barely functional motive system

flesh
where found
was rotting and necrotising

"don't afear!
he's animated!

government approooved!"

i watched him
voiceless for an era

"so"
he started
"what would you be out here for"
chewing ear

"i just came out"

"protection?" he squinted

i stared at him
for intent or meaning

"ha ha!! ooohhweee!
girl
you don't hesitate on shit like that
if you have anything
you must present it
or they will know
and you have no control over the situation"


he laughed inebrelation
"damn girl
you need to learn something fast.

YOU ARE FOOD"

he leapt down from spit's shoulders
"this is a hungry world

and you look delicious"

my right leg snapped a sharp arc
inverse kinetically guiding my foot's final destination
squarely in his groin

he bent over
shaking

"who are you?"

in between gasps for air and spasms of pain
something like "texas"

"give me your weapon"

"look i told you i ain't gonna eat you!
i'm fat and happy right now

i was just warnin ya of others

warnin to watch out how they see ya
and never give them control over you"

he looked at me
closer

i could feel the pit of stomach turn
under the coldness of other people's eyes

"are those attached?
what are they?"
he asked eyeing the bony growths out my back

"they're wings"

it was strange the alienation
and separation i felt
under his eyes

as i stared at him with all my focus and attention
my joke seemed hollow and awkward

"they look like teeth
long crazy pointed teeth

you got a great kick there
you're quite the little ninja there ain't ya?
ooowhee! yeah... well so is that where you are hiding your beads?"
he said
looking straight at my makeshift top
where my breasts were wrapped in an indian silk
after the growths had ruined or made impossible all other protections


my right leg snapped a sharp arc
inverse kinetically guiding my foot's final destination
squarely in his groin
with a little twists of the heel

"oh shit! oh shit! oh fuck
i think you popped one that time
ooooOOhh.. " deep breath " shiit..!"

panting

"ohho missy!!! i diid not mean that...
disrespectfully..
i meant
i meant your beads
your dreams
your hopes
everyone's got a couple of them
though they're ashamed as hell and keep 'em hidden
i just hadn't figgered where you were hiding them

don't tell me you ain't figgered it yet?

here... " he pulled a small bag from a chain around his neck
and tossed it over to me
"those are mine"


i opened the leather tie at the opening of the bag
and saw three tiny glass marbles
glinting unexpectedly bright in the dull haze of the day

"that clear blue one there
the one with all those bright silver flecks
that's my land to live on

i always wanted a place to live
some place to settle
and stop haffin to wander around everywhere
looking for something to eat

a place that grows the food still

that bigger red one
the one with orange inclusions that look like a fire
that's for my wife

wimmin love a man with property

she's gunna be one of them blonde ones
like they have on the coast
with big titties and a love to feed her man!

and that one there
the green and pink one with all them swirlies
that's my daughter

she'll be the perfect angel
and i'll get to sit outside with my thirty ought six
chasing away all the boys
and she'll take care of me and my wife
as we get older

ain't them reasonable things for a man to dream of?"

i tied together the bag
and tossed it back to him

"so you ain't ever collected any dreams?"

"no i've never seen anything like them"

"iff'n you don't keep 'em close to you
they'll eventually get brittle and dust away

you won't remember 'em no more.


you'll find em after long nights of whiskey
in your bed or yer porch whathaveya
wherever you been blabbin' about inside
or sometimes out loud when you've really been hittin' the bottle
you know what i mean!.. ha!

they're not hard to find
even if you just dream a little
i'm surprised you ain't bumped inta them before"

"i think i dream a lot"

"anything you remember?"

"no
i don't recall"

it was strange
i could remember my symbolgical obsessions
i could see their great immediacy
and the fevered nights
but i was numb to any future dreams

there were pains and exhaustions
that had grown into a skin
a rubber membrane muffling the noise
and desires

i had no idea and no desire to idea
and realised that my mind had fried much worse than earlier expected

i didn't
have
any
dreams
anymore

i just wanted to escape the incessant fantasies
the recollections
and obsessions
that had haunted me so deeply of late

i didn't want to be flawed
and broken
in other people's eyes


was that a dream?

"so you interested in finding out more about the beads?"

i startled in my wanderings
"the punks

they love the beads
they gamble with them
use them as weapons
and other things i'll leave for you to discovery

they hangout under the great multipass
where this highway meets the great eastward escape
if you keep headed down
you can't miss them"

"give me your weapon"

"huh?"

"give me your weapon"
i shifted my weight off my right leg

"oh waiwait! here!"

he pulled out his hunting rifle
and handed it over
cautiously avoiding reaching for the trigger

"why is his name spit?"

"you ever tasted him?"

Interesting, but the layout makes it really hard to read. What's that
about?

to
as i travelled towards the punk encampment
across the valley with the great highway multipass in sight
i fell into a deep obsession
linguistically associating the german traume or dream
into a meaningful correlation with multisection

i saw it play as a character
in a dance with variables and differentials
projections
into multisected weyl algebras

these are quotients of k[d, x, m0, m1, ..., m_(n-1)]
under the relations

dx - xd = 1
mk d = d m_(k+1) (+1 done in equivalence classification [n])
mk x = x m_(k-1) (-1 done in equivalence classification [n])

there was an experience of confusion and vertigo at the twisted nature of the interaction
which i immediately recognised as being vaguely number theoretical
and so nauseating

it was the products that picked at my stomach
as operators on the space of functions
they each played their own part in the full calculus

x.(f . g) = f.(x . g) = f.(g . x) = full permutations
d.(f . g) = (d . f).g + f.(d . g)
and
most amazingly

n-1
---
\
mk.(f . g) = / (mj . f).(m_(k-j) . g) (-j done in equivalence classification [n])
---
j=0

so product relationships are tightly determined
in such an algebra of operations

plus
there is an interesting multiplication law
that ties together values achieved by the functions upon application

if f(x) . g(y) = h(x, y)
then (m_(k1) . f(x)).(m_(k2) . g(y)) =

n-1
---
1 \ -j(k2) j
- / w m_(k1 + k2) . h(x, w y)


n --- n n
j=0

on the cracked and twisted highway that
in it's undulations
provoked these idlings and wayling
i found blowing in the breeze
a trail of some discarded trash from distant times
papers and packaging
leading to a box inscribed with
"Steel Mountain RPM: product you can trust!"

and i thought over the product rules
as they had developed for the generalised trigonometry
and i saw the multisected weyl algebras hold steady across deformation

i blinked

with a shameful kind of certainty i knew this held the answer

the multisection operators were projections
they dissected the hypergeometrics
in ways that propagated these product laws

the operator space would map the hypergeometric tori
and their q-deformations

i could feel my fingertips tingle
in that excitement i knew and hated so well

i walked right into the punk encampment before i realised any caution

i had become a walking excuse for selection

i could feel the touch of their eyes

i was awkward to them
but strange enough not to quickly devour

i could tell they each had the confidence of hidden skill
some secret trick of knives or body or alliance
that secured their survival

after a brief instance of the gaze
i felt it leave
returning to it's previous tasks

and the camp filled with background noise

it was a strange type of chaos
primordial and raw

the mass of the community was laid around
the ruins of an old overpass

the angular fall of the concrete
provided caverns
and levels
and stages
for groups to assemble

i had approached from the main street heading under it
a wide street with two tall brick industrial buildings
framing the structure as i had approached


but i had only regained awareness here at the mouth
with eyes on me


.. .. ..

..

two lusters on the corner turned in their throws
continuing to look as the noise returned


"you lost? or found?"
the girl on top demanded

even now
awareness was only relative to my previous state
and my mind did not connect immediately
the meaning of the words


"i don't know"

"why did you come here?"


i shook my head

i needed a second to gather my grounding
but i felt urgent to respond to their questions


"are you on something?"

"can i have some?"
the guy on the bottom immediately begged

"i think i wanted to learn about the beads"
i realised

"like gambling?"


"no"

their eyes stared out at me
expecting the explain


"i just wanted to find out about them"


"really?"


"what's you mean by find out about them?"
"where to get them?"

stepping on each other's sentences

i could come up with answers no longer
and stared back
expecting reprieve


"you sound like ex0du5"
he said

"yeah go bug ex0du5
he's your kinda freak"

..


"the jahman over there in the corner"
"over there under the overhang"
they urged

stepping into the crowded gathering
i felt myself retreat the safety of symbolism

my tendrilmind kept feeling out the tori
expanding and repeating and condensing and arranging
the pieces in which it all laid out

through the basic correspondence of the generalised trigonometry with the generalised polynomials
there had been derived a semigroup ring W [x] for each collection of n-trigonometrics
n

one of the roots of the corresponding generalised polynomial
corresponded to an inversion of the generalised trigonometric

the ring on which W [x] constructed the generalised polynomials
n the nth-cyclotomic ring of integers C
was finitely generated n

2 n-1
the basis was simply the n nth-roots of unity 1, w , w , ..., w
n n n

n
this basis defines a simple surjective morphism m: N -> C
n
which n n
through the canonical N -> k[N ] algebra basis embedding
where k is the cyclotomic field Q(w )
n
carries along to show W [x] is finitely generated as an algebra
n
a very simple and obvious result
but one i still regularly went over in my machinations
distantly recalled from the hagen


being an integral ring phi(n)
the embedding of C into the free Z
n -1 -1 -1
induces an injection W [x] -> k[x , x , x , x , ... , x , x ]
n 1 1 2 2 phi(n) phi(n)

so W [x] is a domain as well and has no zero divisors
n

so i can form the natural geometric structure G = spec(W [x])
n n
and each point of G is given by a homomorphism p: W [x] -> Q(w )
n n n
* *
or alternatively through a corresponding p : C -> Q (w )
n n
onto the multiplicative subgroup of the coefficients


on this variety G
n
it is possible to define a pointwise multiplication

* * * *
(p p )(c) = p (c) p (c)
1 2 1 2

where c is an element of C
n
giving G the structure of an algebraic group
n

now ~ * ~ *
the group of points obeys G = hom (G , Q (w )) = hom (G , Z) (x) Q (w )
n Z n n Z n Z n
~ phi(n)
and since hom (G , Z) = Z
Z n
~ phi(n) * ~ / * \phi(n)
G = Z (x) Q (w ) = | Q (w ) |
n Z n \ n /


a torus!


there are many representations of tori found in algebra

a subgroup of GL (K) is called a torus if it is abelian
n and consists of semisimple elements only

the semisimple elements are the ones that are diagonalisable

take the exponential

| 0 1 0 0 0 . . . 0 |
| 0 0 1 0 0 . . . 0 |
| 0 0 0 1 0 . . . 0 |
| . . . . . . . |
| . . . . . . . |


| . . . . . . . |

| 0 0 0 0 0 . . . 1 | | g (x) g (x) g (x) . . . g (x) |
| 1 0 0 0 0 . . . 0 | x | 0 n 1 n 2 n n-1 n |
e | |
| g (x) g (x) g (x) . . . g (x) |
which becomes | n-1 n 0 n 1 n n-2 n |
| |
| g (x) g (x) g (x) . . . g (x) |
| n-2 n n-1 n 0 n n-2 n |
E (x) = | |
n | . . . . . |
| |
| . . . . . |
| |
| . . . . . |
| |
| g (x) g (x) g (x) . . . g (x) |
| 1 n 2 n 3 n 0 n |


which is circulant and diagonalisable

also A tr(A)
from the formula det(e ) = e

x x
for n=1 gives trivially e = e

and for n>=2 gives det(E (x)) = 1
n 2 2
which generalizes the classical ch (x) - sh (x) = 1

there is also tr(E (x)) = n g (x)
n 0 n

E (x) is a one dimensional subspace
n

now notice that
using the sum rule for generalised trigonometrics

we have E (x + y) = E (x) E (y)
n n n

so it's abelian
and a torus

and looking at


| 1 0 0 . . . 0 |
| |
| |
| 0 w 0 . . . 0 |
| n |
| |
| 2 |
| 0 0 w . . . 0 |
| n |


| |
| . . . . . |
| |

| . . . . . |
| |
| . . . . . |
| n-1 |
| 0 0 0 . . . w |
| n | x
e


which equals | x |
| e 0 0 . . . 0 |
| |
| w x |
| n |
F(x) = | 0 e 0 . . . 0 |
| |
| 2 |
| w x |
| n |
| 0 0 e . . . 0 |


| |
| . . . . . |
| |

| . . . . . |
| |
| . . . . . |
| |
| n-1 |
| w x |
| n |
| 0 0 0 . . . e |


again it is easy to prove for n >=2

det(F(x)) = 1

and generally tr(F(x)) = n g (x)
0 n

this is also a torus

and together these can be used to generate sl (C)
n

and i recalled the polar decomposition

..


i couldn't get far in my thoughts
as the little bend of concrete i was avoiding
laid itself before me despite my designs


he must have been the jahman they spoke of

he was the only black man i had seen in the camp
despite the wild assortment of color and design present


he had lovely thick dreads hanging

. .
shoulder length and gnarlled falling


wrapped around his head


he saw that i had seen him and smiled
walking over to me and handing me a music disk


" avez-vous vu cette merde?
tricknology de l'avenir
si je suis grudge "

" ils parlent français ici? "

he laughed a deep laugh

" vous avez fait deux!
si vous parlez la langue des méchants? "


" j'ai toujours temps de verbes en ruine "

" you speak 'da english tongue? "

" yeah
mostly "
i said meekly

" all right 'den check out 'dat bass bomb of noisarchy 'dere!"

i looked over the disk he had given me
it seemed eerily familiar

i felt this slow shiver at the base of spine
work a slow rhythm up my back


it was called:

i read through every entry with the tingle and expectation of déjà vu


but i hadn't had the time last year

what with unexpected vacations and company trips
and my lapse into mania about the symbology of multisection

i hadn't put together an eXterminatingAngel like the other years

but the titles were all there

i recognised the songs
though i had never compiled it before
or drawn the cover art that
once again
had my itty bitty deformity
re-enacting some apparently mesoamerican/post-nuclear end-of-the-world


"i didn't do this" i told him
simply


"of course not
'dis is one-a galathaea's ee-ays!"


"yeah"

i have been confused for so long
my distance is an armor of silence

"i didn't do this"

he chuckled deeply and looked over me


i hated the growths out of my back with such despair
i felt weak in his eyes


"et pourquoi galathaea viennent me rendre visite?"

"je"

connections were difficult again
i desperately wanted the tao of silence

"j'ai des rêves

mais jamais de trouver des perles?"

i turned it into a question

"aha!" he shouted
smiling

he reached for a large brown backpack at his side
