Is there a person who can calculate using any computer algebra
system the exact value of the following limits
--------------------------- Limit # 1 ---------------------------
limit(z^2 *
int(int(1/(x*y*(x^z+y^z)), x= 1..infinity), y= 1..infinity),
z= infinity);
--------------------------- Limit # 2 ---------------------------
limit(z^2 *
int(int(1/(x^2*y^2*(x^z+y^z)), x= 1..infinity), y= 1..infinity),
z= infinity);
--------------------------- Limit # 3 ---------------------------
limit(z^2 *
int(int(1/(x^z*y^z*(x^z+y^z)), x= 1..infinity), y= 1..infinity),
z= infinity); ( wow! ;)
The other day I was quite surprised to find that... well, I'd
better hold my tongue for a while :)

The integral is ln(4)/z^2 when it converges, so the limit is ln(4).

Due to symmetry of integrands this is irrelevant, but the seemingly
reversed orders actually conform to those of the original problems.
Mathematica semantics for multiple integration works from outermost
inward.
In[8]:= Limit[z^2 *
Integrate[1/(x*y*(x^z+y^z)), {y,1,Infinity}, {x,1,Infinity}],
z->Infinity]
Out[8]= Log[4]
In[12]:= InputForm[l2 = Limit[z^2 *
Integrate[1/(x^2*y^2*(x^z+y^z)), {y,1,Infinity}, {x,1,Infinity}],
z->Infinity]]
Out[12]//InputForm= -EulerGamma - PolyGamma[0, 1/2]
In[13]:= FullSimplify[l2]
Out[13]= Log[4]
In[14]:= InputForm[l3 = Limit[z^2 *
Integrate[1/(x^z*y^z*(x^z+y^z)), {y,1,Infinity}, {x,1,Infinity}],

..................................................................
JB> what the point is in [...] collecting these bugs
In a nutshell, one of the final goals is making all the Maple's
consumers' life easier via making Maple faster, more stable and
so to say, more intelligent.
So, one of the goals is to HELP Maplesoft to improve Maple if
the company wants this, and to FORCE Maplesoft to improve Maple
if the company does not wants this. The maximal public Maple bugs
exposure is a tool of our users' influence on the wistful case.
More reasons:
1) It might be time-consuming to realize that the given behavior
of a software application (say, Maple) is a bug, and is it
possible to circumvent it, and if yes, what is a work-around.
2) Over a decade (!) Maplesoft ignores the numerous consumers'
requests to fix a bug even if it is had been shown publicly,
this cannot be construed in other terms as a piece of SHAME.
For example, see
Maple bugs: Big festal day
http://groups-beta.google.com/group/sci.math.symbolic/msg/6002b726f9f2e669?hl=en

but you are claiming to be a leading CAS expert. i don't see how
identfying bugs would qualify you as a CAS expert. sure, your bug
collecting will help a lot of Maple users, but i don't see how that
entitles you to the title of a leading CAS expert. i saw your website
and cv, and noticed that you don't have single journal paper published,
only some poster papers at small conferences.
i also think that you have been approaching everything the wrong way.
your brashness will not win any potential customers over, and that
episode that you are having with Jerzy something (sorry i don't
remeber how to spell his last name) is rather embarassing and makes you
come across as a crackpot. it's bad for business so i would suggest
that you get off your high horse and show some humility. anyway, good
luck with whatever it is that you do if it will be of some use to some
people.

Forget those claims, everybody sees what is to see.
Actually a disordered bug collection helps *only* the implementors,
able to pinpoint the source of the disease, structural, algorithmic,
etc. This is a matter for serious *collective* work, cross-checks, etc.
But who will cooperate with this individual?...
Maplesoft perhaps?
Or SciFace/University of Paderborn, the MuPADmen?
Ask them, please... Show me ANY collaborator. Try to contact people
mentioned as 'references' on his personal page (not all links work).

Do you *really* believe in this business? In customers, real or
potential? Let's be serious. Perhaps you believe also in this "team
of programmers" under the rulership of Mr. Bondarenko? Perhaps they
should take part in this discussion, they should have access to
Internet, I suppose. I wonder why they remain silent, instead of
defending their "boss".

i don't know what to be believe, though it does seem to me that he is
the only person in his "company". but he must make a living somehow.
i've noticed his postings on sci.math for a while but never figured out
what these challenges are all about (except for their weirdness), that
is until i stumbled across that episode he was having with you.

still conferences are only conferences, and, worse still, your paper
was only a poster paper. where are your journal publications? how come
an expert has none of these? anyway, standards for a good conference is
different from standards for good journals ==> papers submitted to
journals are reviewed much more rigorously. i guess you didn't know
that.

Hello Jay Bryant,
JB> still conferences are only conferences,
Let me again point out, *International* and *Symposium*
http://www.mmrc.iss.ac.cn/~issac2005/callpaper.htm
ISSAC is the yearly premier international symposium
in Symbolic and Algebraic Computation. It provides
an opportunity to learn of new developments and to
present original research results in all areas of
symbolic mathematical computation. Planned activities
include invited presentations, research papers, poster
sessions, tutorial courses, vendor exhibits and
software demonstrations.

You sound like a superciliary professor who has a dozen

almost all are very polite persons, God thanks)
So I decided to find where is your site located, and read
5-10 your papers (pubished in journals) to learn from you.
However, to my utter disappointment, I found neither your
site nor even a tiny home page nor a single paper. So maybe
you kndly point out where to read your stuff, if any?
Over 15 years I keep working in the field of computer algebra
and software testing, and remember by heart many many dozens
names of the researcher - but not your name.
JB> papers submitted to journals are reviewed much more

A 2 cent value trick. Failrly chintzy. I have an impression
that you simply have much time and decided to chat with us.
This firm impression came from the fact that upon reading
almost all of about 50 your messages I, with even stronger
disappointment, found that you wrote on religious themes,
and many of your posts are just general comments like

Maybe because of lack of your understanding what's going?
1) what we do for general public - the Maple Bugs Encyclopaedia -

2) currently, Cyber Tester, LLC offers NO services for individuals

3) to call a spade a spade, in computer algebra and software testing
you are a sheer ignoramus, and because of this fact, you are not

4) graduate from kindergarten, go to school, finish grad courses,
educate yourself, and maybe you see the world in brigher colors.

This is a light-weight answer, good! But ...
It is obvious that after seeing the *Stalinist denunciations*
sent to my Univ. administration, the "recommendation letters"
addressed to Maplesoft, throwing mud on their collaborators,
or a posting addressed to J. Klimovitch, which not only
offends him in a most scandalous manner, but also unveils
his personal data,
people who will to say about V. Bondarenko what they want to
say, must protect their identity, unless (as myself) they
don't care.
Since - as it seems - several dozens of people reading those
newsgroups where Mr. Bondarenko produces himself, are deeply
disgusted, I believe that it is honest to warn people whom
V. Bondarenko treats as his "references" /a selection; not
all are reachable.../: -------------

you as an expert. who is citing anything you have worked on, has nayone
ever invited you to give a technical talk about your work. i guess the

I must inform you sadly that, alas, a worker of l'Universite' de
Caen Basse-Normandie, some Jerzy Karczmarczuk, continues defaming
your organization.
The day before yesterday, on Monday, 6 Jun 2005 12:19:18 I've
sent you a carbon copy of a report on improper behaviour of this
person.
The main copy had been addressed to Professor Bretto from whom
I really expected help in stopping the insulting messages the
above-said Jerzy Karczmarczuk posts into Google Groups.
Being too much immersed into research activity, I did not visit
the Google Groups yesterday. However, today, on June 8, 2005,
with much surprise, I discovered the following remark from Jerzy
Karczmarczuk showing his full disrespect to me, to you, to the
whole administration of your University, and thus, to the whole
l'Universite' de Caen Basse-Normandie:

JK> Until now I was the only one in my department who knew that
JK> we have a mentally sick person in this newsgroup, now there
JK> are more. Imagine the explosion of laughter when one of the
JK> receivers of this text of Bondarenko:
> A leading world's CAS researcher, the inventor of the LIFT and
> CYCLE technologies to be demonstrated in the near future, I am
> sorry to inform you [...]
JK> tried, being a serious person, to verify on the Internet the
JK> case of this "leading world's CAS researcher", to find his
JK> publications, software, or *whatever*.
My detailed answer to this person you can find here:
http://groups-beta.google.com/Âgroup/sci.math.symbolic/msg/43Âd5b8a162e...
The behavior of Jerzy Karczmarczuk who even does not acquainted
with me personally, and who does not have any relation to the
field I am working in, automated software testing, cannot be
described in other way as a wilful trespass, an wilful illegal
act against my rights.
Being a linguist, I hope that upon reading the statements made
upon me, you certainly feel that I am right.
I kindly request from you that you stop at last the described
improper actions of a worker of l'Universite' de Caen Basse-
Normandie, Jerzy Karczmarczuk wrt to me. Having too many a
task on software testing automation, I hope that I will not
be forced to get involved in further handling of this case.
Just a detail, if the libel sent by Jerzy Karczmarczuk and the
scandal would continue further, what would think your potential
students about joining your University where their rights could
be broken so easily?
Thank you for your assistance in advance.
Best wishes,
Vladimir Bondarenko

Dear Professor Bretto,
A leading world's CAS researcher, the inventor of the LIFT and
CYCLE technologies to be demonstrated in the near future, I am
sorry to inform you that a worker of l'Universite' de Caen Basse-
Normandie, some Jerzy Karczmarczuk, defames your organization
via systematic sending publicly the insulting messages.
I am too busy with research work; but now I am feeling that the
time has come to stop the improper behaviour of Jerzy Karczmarczuk
and ask for your resolute help in modifying the behavior of this
person.
Here you can find some samples of his statements about me, a person
whom he never even met.
http://groups-beta.google.com/Âgroup/sci.math.symbolic/msg/12Â837905fcf...
JK> person, whose ego reached the stage needing a competent
JK> psychiatrist.
JK> the insulting slogans, as taken directly from an Ancien
JK> Regime era...
http://groups-beta.google.com/Âgroup/sci.math.symbolic/msg/b9Â9b43362b2...
JK> This fellow Bondarenko visibly suffers from a heavy mental
JK> disorder.
JK> Insane people usually deserve some compassion
JK> perhaps he will be compelled by somebody to undergo a medical
JK> treatment...
http://groups-beta.google.com/Âgroup/sci.math.symbolic/msg/16Âca1e7dd9c...
JK> a clinical idiot
JK> V. Bondarenko is not capable of understanding the simplest
JK> logic.
http://groups-beta.google.com/Âgroup/sci.math.symbolic/msg/26Â62a66c1d5...
JK> a person far from mental equilibrium
and more, but I hope the quoted links will do.
Also please note that, at any rate, Jerzy Karczmarczuk goes easily
beyond his competence, a big defect for a research worker as well
as an instructor.
Had you need any kind of support to drive the nail home please
don't hesitate to let me know and I guarantee you the strongest
backstop imaginable to stop the above demonstrated disorderly
conduct.
Best wishes,
Vladimir Bondarenko
