Topic #1 ----------- OP-SF NET 13.4 ------------- July 15, 2006
~~~~~~~~~~~~~~
From: OP-SF NET Editors
Subject: Delay in this issue
We regret that this issue is being sent to SIAM on July 24 well past its
nominal date. The reason is that when we prepared a first draft around
July 8, we had very little news to report and promises of a number of
items to come in the following two weeks. We hope the delay has been
worthwhile and that readers will find this issue of interest. Readers
are invited to send all items of interest (especially news of meetings,
books, etc) to the editors. Don't assume that we know about them or will
hear about them from others.
Topic #2 ----------- OP-SF NET 13.4 ------------- July 15, 2006
~~~~~~~~~~~~~~
From: Peter Clarkson
Subject: ICIAM 2007
In 2007 there will be no SIAM annual meeting since the Sixth
International Congress on Industrial and Applied Mathematics (ICIAM07)
will take place in Zurich 16-20 July 2007 (further information is
available on www.iciam07.ch). Previous meetings of ICIAM have been held
in Sydney (2003), Edinburgh (1999), Hamburg (1995), Washington DC (1991)
and Paris (1987).
I would like to organize at least one mini-symposium on aspects of
"Orthogonal Polynomials and Special Functions". Each mini-symposium
consists of either one session (four talks of 30 minutes [including
discussion]) or two sessions (eight talks of 30 minutes [including
discussion]). The closing date for the submission of proposals for
mini-symposiums is 31st August 2006. If anyone is interested in taking
part in a mini-symposium on "Orthogonal Polynomials and Special
Functions" at ICIAM07, then please let me know as soon as possible
(Email: P.A.Clarkson@kent.ac.uk). This is only an expression of interest
at this juncture rather than a commitment.
During ICIAM 2007, the Euler Lecture will be given by Walter Gautschi,
Purdue University. This lecture is to commemorate the 300th anniversary
of the birth of Leonhard Euler (1707 - 1783). It will be given on
Wednesday, 18 July 2007 from 6-7 pm.

Topic #5 ----------- OP-SF NET 13.4 ------------- July 15, 2006
~~~~~~~~~~~~~~
From: Vladimir Novikov, Juri Rappoport
Subject: Arnold Fedorovich Nikiforov (1930-2005)
The distinguished Russian mathematician and physicist Arnold Fedorovich
Nikiforov died on 27th of December 2005, nearly a month and a half after
his 75th birthday. A vivid personality of splendid health, having
planned some new work in summer 2006 in the USA, he suddenly caught a
virus infection and died in hospital less than two months later.
Born in Saint-Petersburg, Arnold F. Nikiforov graduated from Moscow
State University in 1955 and having worked for about a year in
Arzamas-16 (Russian Nuclear Center), he joined the Keldysh Institute of
Applied Mathematics (then a Branch of Applied Mathematics of the Steklov
Mathematical Institute), where he worked for the rest of his life.
Academician A. A. Samarskiy, at that time a candidate of physical and
mathematical sciences, assigned him the problem of calculating Rosseland
free paths accounting for absorption in spectral lines.
The problem arose from modeling a power explosion and the need to
describe energy transport at high temperatures. The large number of
physical effects connected with absorption in spectral lines (in other
words bound-bound transitions) made the task extremely complicated both
from the point of view of the theory and the volume of calculations. The
search for the relative role of various effects was carried out. The
volume of calculations was reduced by using special quadrature formulas
based on classical orthogonal polynomials. Fast convergence iterative
methods for calculation of eigenvalues of energy (in particular, phase
method) and special approximations for wave functions were developed. It
was shown that, for high temperatures, the absorption in spectral lines
is very important for many-electron atoms. In some cases, this effect
decreases the free path by almost an order of magnitude. This result
appeared to be much more in conformity with experiment. In 1962,
A.F.Nikiforov was awarded the Lenin Prize, the Soviet Union's highest
scientific award, for this work.
Work on quantum statistical models of hot dense matter and calculation
of absorption coefficients was continued in collaboration with V.G.
Novikov and V.B.Uvarov. The results of this hard and long-term work were
systematized and published in a monograph in 2000. After it was
essentially transformed and completed, the book was translated into
English and published in 2005 by Birkhauser Verlag.
In the 70s, A.F. Nikiforov and V.B. Uvarov started their work on the
theory of special functions and their applications. They developed an
absolutely new and rather simple approach, which unified the
construction of the solutions of differential equations of
hypergeometric type. This particular approach permitted a great
simplification of the method of solving a wide class of tasks for
difference equations also. On the basis of this approach the authors
constructed the theory of classical orthogonal polynomials of a discrete
variable as solutions of a difference equation of hypergeometric type on
uniform and nonuniform lattices of certain classes. It has been found
that these solutions include as particular cases the polynomials
introduced earlier from various points of view by Markov, Chebyshev,
Hahn, Meixner, Krawchouk, Charlier, Rogers, Stieltjes-Wigert, Pollaczek,
Karlin-McGregor, Al-Salam-Carlitz and also the Askey-Wilson polynomials.
In addition, it has become clear that the Clebsh-Gordan and Racah
coefficients, which were known to physicists long ago and which have
long been used in the theory of group representations, in atomic and
nuclear spectroscopy, were in fact only variants of the above-mentioned
polynomials. Three monographs were written on the basis of this work.
Later on, these books were rewritten, completed, translated into English
and French and went through several editions. The work on special
functions as well as on quantum statistical models of hot dense matter
was acknowledged by many outstanding mathematicians and physicists.
A.F. Nikiforov, being a professor at Moscow State University for many
years, delivered lectures on special functions, on mathematical physics
and on computational methods of quantum mechanics. He lectured for the
students who, for their part, loved and respected him greatly. Among his
former pupils there are many doctors and professors.
Arnold F. Nikiforov was a proficient slalom skier. As a student he
participated in ski-jumping competitions and ski races. He admired
mountains and took part in alpinist expeditions to the Pamir and
Caucasus in summer and winter. As a slalom skier he conquered the
mountains of Tien-Shan, Kamchatka, Gornaja Shoria, Prielbrusje,
Appatites, Chimbulak and the Alps. His colleagues, friends and all
around him were always touched by his sincerity, kindness and absolute
devotion to his science.
Vigorous, lighthearted, modest and at the same time very enjoyable
person, - this is how Arnold Fedorovich Nikiforov, a great man and a
wonderful scientist, will stay in our memory.

From: Krishna Alladi
Subject: Ramanujan, Sastra Prize, etc
The June/July 2006 issue of the Notices of the AMS contains a feature
article by Ken Ono about his visit to Kumbakonam, India (Ramanujan's
hometown) and his participation in the conference at SASTRA University
in December 2005 when the First SASTRA Ramanujan Prizes were awarded to
Manjul Bhargava (Princeton) and Kannan Soundararajan (Michigan). This
issue can be viewed on line at
http://www.ams.org/notices/200606/200606-toc.html
The front cover of this issue contains a copy of a letter written by
Ramanujan.
Also in this issue, in the section on Mathematics Opportunities, is the
announcement (call for nominations) of the 2006 SASTRA Ramanujan Prize.
I WOULD APPRECIATE HELP FROM YOU IN SPREADING THE NEWS ABOUT THE CALL
FOR NOMINATIONS OR BY MAKING A NOMINATION. See the web site
http://www.math.ufl.edu/sastra-prize
Finally, there is also an announcement in this issue of the award of the
First Proceedings of the National Academy of Sciences Prize to Karl
Mahlburg for his paper "Partition congruences and the
Andrews-Garvan-Dyson crank", see
http://www8.nationalacademies.org/onpinews/newsitem.aspx?RecordID=03282006
Mahlburg gave an hour lecture on this at the SASTRA Conference in
December 2005. THE THEME OF THE NEXT SASTRA CONFERENCE, DEC 20-23, 2006,
THAT SOME OF YOU MIGHT BE INTERESTED IN ATTENDING, WILL BE NUMBER THEORY
AND COMBINATORICS.
As some of you may know, I have written two articles
"A pilgrimage to Ramanujan's hometown"
and
"The First SASTRA Ramanujan Prizes"
which are available at the UF Math Dept web site
http://www.math.ufl.edu/sastra-prize/
Both articles have appeared (the second in abridged form) in the May
2006 issue of FOCUS published by the MAA. The May 2006 issue of FOCUS
which has appeared in print, is available online at

Topic #7 ----------- OP-SF NET 13.4 ------------- July 15, 2006
~~~~~~~~~~~~~~
From: Dan Lozier
Subject: Looking Ahead to the DLMF
The Digital Library of Mathematical Functions has been a much bigger job
than any of the project participants expected. I am pleased to report
that all of the chapters are in the final stages of editing and
validating. The process of selecting a publisher for the print edition
has been mapped out according to NIST and US Government procurement
rules. The procurement will be competitive among qualified mathematics
publishers.
In addition to the print edition, the DLMF will be distributed free from
a public Web site at NIST. The Web address is http://dlmf.nist.gov. A
sample chapter on Airy functions has existed on this Web site since the
beginning of the project. A tremendous amount of work has been done on
the Web site since then to improve its "look and feel." A new sample
chapter on the gamma function is being prepared. It will be on the Web
site by the end of the summer.
The DLMF project is modeled after the Handbook of Mathematical
Functions, edited by Abramowitz and Stegun, and published in 1964. It is
being constructed by the National Institute of Standards and Technology
with substantial funding contributions by the National Science
Foundation. More than 50 individuals are contributing to the project as
paid authors and validators. The staff at NIST consists of another dozen
or so people.

Subject: Sum of even terms in E_q(q) related to root system E_8 ?
In the preprint
http://www.arxiv.org/abs/hep-th/0404120
Werner Nahm,
Conformal field theory and torsion elements of the Bloch group,
Contribution to Les Houches Lecture Notes, March 2003
the Introduction mentions the conjectured identity
\sum_{n=0}^\infty \frac{q^{2n^2}}{(q;q)_{2n} =
\sum_{m_1,\ldots,m_8=0}^\infty
\frac{q^{mCm}}{(q;q)_{m_1}\ldots(q;q){m_8}}
where C is the inverse of the Cartan matrix of the exceptional Lie
algebra E_8.
The formula has been checked to high order by computer algebra.
Note that the left-hand side is the sum of the even degree terms in the
power series of E_q(z)=(-z;q)_\infty for z=q.

From: OP-SF NET Editors
Subject: About the Activity Group
The SIAM Activity Group on Orthogonal Polynomials and Special Functions
consists of a broad set of mathematicians, both pure and applied. The
Group also includes engineers and scientists, students as well as
experts. We have around 140 members scattered about in more than 20
countries. Whatever your specialty might be, we welcome your
participation in this classical, and yet modern, topic. Our WWW home
page is:
http://math.nist.gov/opsf/
This is a convenient point of entry to all the services provided by the
Group. Our Webmaster is Bonita Saunders (bonita.saunders@nist.gov).
The Activity Group sponsors OP-SF NET, which is transmitted periodically
by SIAM. It is provided as a free public service; membership in SIAM
is not required. The OP-SF Net Editors are Diego Dominici
(dominicd@newpaltz.edu) and Martin Muldoon (muldoon@yorku.ca).
To receive the OP-SF NET, send your name and email address to
poly-request@siam.org.

For several years the Activity Group sponsored a printed Newsletter,
most recently edited by Rafael Yanez. Back issues are accessible at:
http://www.mathematik.uni-kassel.de/~koepf/siam.html
Given the widespread availability of email and the Internet, the need for
the printed Newsletter has decreased. Discussions are underway concerning
whether an annual printed Newsletter or Annual Report should be
instituted.
SIAM has several categories of membership, including low-cost categories
for students and residents of developing countries. For current
information on SIAM and Activity Group membership, contact:
