this might be a silly question.

but since i like tetration and FLT and Beal , the analogue idea occured to me :

let x,y,z,a,b,c be integers >= 3

has x^^a + y^^b = z^^c got a solution ?

Why just don't read about Ferma theorem?

I think by x^^a he means something different from x^a.
Even if x^a was intended, note the different exponents,
so it's not Fermat's Theorem.

Yes, you are right. My bad.

YES IT IS.

x^^a = x^a1 for some integer a1.

Why is this difficult?????

Mea Culpa. I did not realize that he intended a,b,c, to be different.

This is, however the same as the so-called Beal conjecture.

if the symbol ^^ means addition, this is trivial.

Of course, no one knows what you mean by ^^, fuckwit. This, like everything
else you post, is total boring off-topic mathforum crap. Mathforum - a
festering vat of immeasurable idiocy.

There's no need for abusive language. The original poster clearly
meant ^^ to mean the tetration operator. Therefore, it seems (to me
anyway) to be a legitimate question.

^^ is tetration or power tower notation !!

seems that some are confused.

x^^2 = x^x , x^^^3 = x^(x^x) etc


apart from stupid irrelevant insults and misunderstandings is anyone (now) able to post something sensible ?

I did. x^^a is x^a1 for SOME integer a1. Thus, x^^a + y^^b =
z^^c is
the same as x^a1 + y^b1 = z^c1 for some integers a1, b1, c1. This
is the so-called
BEAL conjecture.

[note that a1 = x^x^x... (a tower of height x-1)] assuming that
x^^a =
x^(x^x^x^x...) where the height of the entire tower is x.

I don't think Tommy's conjecture is completely equivalent to the Beal
conjecture. A solution to Tommy's equation gives a solution for the Beal
conjecture (taking a1 = x^^{a-1}, b1 = y^^{b-1} and c1 = z^^{c-1}), but a
solution to the Beal conjecture doesn't necessarily give a solution to Tommy's
equation.

It is conceivable that one may have:

E a1, b1, c1:

x^{a1} + y^{b1} = z^{c1}

but the a1, b1 and c1 may NOT necessarily be decomposable as towers of x, y and
z.

My guess is that nothing is known about this conjecture and it will probably
stay like this, for a long time.

Thank you.

I im waiting for World Wide Wade , Robert Israel and Dave L Renfro to reply.

These are in my not so humble opinion x) the best posters on sci.math and notable for their non-hostality towards tetration.

Of course you and other members of the tetration forum are also potential intresting posters in this thread.

and of course anyone is welcome to post.

btw , i wonder if Ioannis thinks i should post this elsewhere too , for instance on the tetration forum ?

also i had the impression that this question does have an answer ; provable or at least reducible towards total dependance on Beal or other well known unsolved number theory problems.

for this impression i added " silly question " to the topic name , but perhaps its not so simple afterall.

maybe this problem requires new math tools ? or in other words is undecidable with current number theory methods ?

but what is 'new' of course ... thats a difficult question , since all 'new' needs to reduce towards 'old' in order to prove its validity.

i have , as you might have noticed , claimed a RH proof based on somewhat traditional number theory proof methods , an ' elementary proof ' that is relatively short and requires no complicated concepts , an '18 th century proof' as lwalke calls (or quotes) it.

( ' elementary proof ' is a defined math term )

despite that RH proof and its consequences ( other number theory conjectures are proven when based upon RH or by a similar proof technique ) this FLT-variant ( TLTT tommy's last tetration theorem :p ) seems immume to the methods i used to proof RH.

( and btw i wonder if RH relates to FLT in some strange way , though FLT has been proven , im looking for short proofs nowadays , basicly by motivation of my relatively short RH proof. Probably not. Never read such a thing , no particular argument to think so , counterintuitive , ... but still who knows ? )

i think i made some progress using galois theory ...

..maybe ...
