Topic #1    -------------    OP-SF NET 6.3   -------------  May 15, 1999
From: Editor, OP-SF NET <muldoon@yorku.ca>
Subject: Passages

The week of April 19 brought the sad news of the unexpected death of
Gian-Carlo Rota, one of the most colourful and original mathematicians of
the past half-century and one whose work touched several areas of interest
to members of our Group. See the obituary notice at

A few days later, we were delighted by the news that Richard Askey has
been elected to membership in the U.S. National Academy of Sciences.  For
many years, Dick Askey has been very much at the centre of activity in
Orthogonal Polynomials and Special Functions and has been a great friend
and supporter of our Group's activities. Congratulations, Dick! 

Topic #2       ------------- OP-SF NET 6.3 ------------- May 15, 1999
From: Charles F. Dunkl <cfd5z@virginia.edu>
Subject: Report on Atlanta

The 1999 SIAM Annual Meeting was held at the Sheraton Atlanta Hotel, May
12-15, in Atlanta, Georgia. As part of the meeting Jeffrey Geronimo of
Georgia Tech organized a minisymposium on "Orthogonal Polynomials: Theory
and Applications". There were seven talks in two sessions. Thursday (May
13), Jeff Geronimo started the program and lectured about multiwavelets
and multiresolution analysis; some of the results were joint work with G. 
Donovan and D. Hardin. Then Percy Deift of the Courant Institute discussed
asymptotics for orthogonal polynomials whose weight function was of the
type exp(-Q(x)), Q being a polynomial of even degree, by means of the
Riemann-Hilbert method. T. Kriecherbauer, K. McLaughlin, S. Venakides and
X.  Zhou had collaborated with Deift on this work. Walter van Assche of
Leuven (who is vice-chair of the Activity Group) talked on multiple
orthogonal polynomials (that is, orthogonal for two different weights)
associated to modified Bessel functions of the second kind. 

Friday (May 14) there were four talks; your reporter discussed examples of
Calogero-Moser systems and orthogonal polynomials with hyperoctahedral
(Weyl groups of type B) symmetry, and the problems involved in trying to
construct complete orthogonal bases of the associated spherical harmonics.. 
Sergei Suslov of Arizona State University talked about a novel type of
Fourier series associated to q-analogues of sine and cosine (some of this
was joint work with J. Bustoz and W. Gosper). H. Woerdeman of the College
of William and Mary talked on joint work with Geronimo about expressing a
positive trigonometric polynomial of two variables as the squared absolute
value of another polynomial, in connection with autoregressive filters.
Gerard Teschl of Vienna concluded the program with his lecture on inverse
spectral theory of Jacobi operators; the information about the operator
which is contained in the support of the spectral measure. 
Dan Lozier (chair of the A.G.) participated in the Poster Session, with an
update on the Handbook project at NIST (National Institute for Science and
Technology). Bruce Fabijonas, also of NIST, talked in a Contributed Papers
session about numerical calculation of modified Bessel functions (software
which could become part of the Handbook accessories).

As often happens at large annual meetings of scientific societies, the
attendance at a parallel session was disappointingly small; it ranged from
12 to 20 at the O.P. minisymposium. One notes there were twelve parallel
minisymposia Thursday afternoon. 

The invited lecture by Herbert Wilf on asymptotic oscillations and binary
partitions of integers certainly was of interest to the special functions
people, notably the asymptotics and combinatorics experts.

The Friday evening pool side reception organized by Dan Lozier provided
good conversation and collegiality, but unfortunately reflected the low
level of attendance at the minisymposium.

Saturday the activity group officers  (named above) met to discuss plans.
One point worth making here: the OP-SF NET and the printed Newsletter are
an excellent way of promulgating information about upcoming conferences,
and we urge the world-wide community of OP&SF people to use these news
media for both announcing conferences and planning programs to avoid
scheduling conflicts.

Subject: 1999 IMACS-ACA

1999 IMACS Conference on Applications of Computer
Algebra, El Escorial, Spain, June 24-27, 1999

The following information has been taken from the WWW site
Further and detailed information can be obtained in the same site. 

Computer Algebra or Symbolic Computing is a young field of research in
between Computing and Mathematics.  Merging the two ways of thinking (one
theoretical and the other closer to the real world) provides a fertile
soil for the growth of new useful and exciting applications. Although the
same kind of tools are in the background, a broad variety of fields are
covered, as the sessions organized at IMACS-ACA '98 show: Robotics, High
Energy Physics, Industry, Algebra and Geometry, Artificial Intelligence,
Education, Biology, ... 

This will be the 5th IMACS-ACA. Previous ones have taken place in
Albuquerque, New Mexico (USA) 1995; Linz (Austria) 1996; Wailea, Maui,
Hawaii (USA) 1997 and Prague (Czech Republic) 1998. The evolution of the
number of talks and attendees indicate a rapidly increasing interest in
this particular conference.

Probably the two most important conferences about Computer Algebra
nowadays are the much older ISSAC and IMACS-ACA. IMACS-ACA is getting
nearly as many attendees as ISSAC. Moreover, as far as we know, IMACS-ACA
is the only conference in the world specifically devoted to applications
of this field. 

In previous years organizations and companies as important as the U.S.
National Science Foundation (NSF) and National Security Agency (NSA),
Czech Ministry of Education, Texas Instruments, Wolfram Research, etc.
have sponsored this conference.

Topic #6       ------------- OP-SF NET 6.3 ------------- May 15, 1999
From: Andre Ronveaux <Andre.Ronveaux@fundp.ac.be>
Subject: Benin Workshop on Contemporary Problems in Mathematical Physics

A Workshop on Contemporary Problems in Mathematical Physics will take
place at The Institut de Mathematiques et de Sciences Physiques} (Cotonou,
Republique du Benin), from October 31st to November 7th, 1999. L'Institut
de Mathematiques et de Sciences Physiques (L'IMSP), as one of the Graduate
Schools of Universite Nationale de Benin, organizes a third Cycle in
Mathematics and Physics since 1989. L'IMSP was the first African
Institution initiated with the support of the Third World Academy of
Science, and affiliated in 1988 to the ICTP (International Center for
Theoretical Physics-Trieste, Italy) created by the late Nobel laureate
Abdus Salam. PhD students coming from many countries around Benin and
being bachelor in Mathematics or Physics, are selected every two years, in
order to start a DEA (Diplome d'Etudes Approfondies), followed by the
preparation during at least two more years of a PhD Dissertation in IMSP
and abroad (mainly Europe and North America).  One of the orientation,
inside Mathematical Physics covers the topic of "Special Functions and
Orthogonal Polynomials".

The main objective of the workshop is to contribute to the development of
a _critical_mass_ of researchers in Africa in such a dynamic area as
mathematical physics. The main _aim_ of the workshop is to bring together
specialists from diverse topics in Theoretical and Mathematical Physics.
It will offer to the international scientific community the possibility of
exchanging useful information on contemporary problems in these fields
through direct interaction.  The workshop will also provide young African
researchers with an opportunity to know each other and to initiate
scientific cooperation. Therefore, the workshop will help to strengthen
research capacity and revitalize activities in mathematical physics in
African universities. The workshop will include invited review talks and
contributed communications. The invited review talks will be presented in
plenary sessions whereas the contributed papers will be presented in three
working groups corresponding to the three main topics. 

Main topics:
1. Coherent States, Wavelets and Geometric Methods in Theoretical Physics
2. Quantum  Field Theory, Atomic and Molecular Physics
3. Operator Theory and Orthogonal Polynomials

The official languages of the workshop are English and French.

The activity is open to scientists from all countries. Travel and
subsistence expenses of the participants should be covered by the home
institution. However, limited funds will be made available for scientists
from African countries. Participants interested in presenting a paper are
encouraged to send a camera ready copy. The deadline for submission of
papers and/or of requests for financial support is July 15th, 1999.

Can anyone tell me if there is any literature on orthogonal polynomials of
order-dependent argument, i.e. a complete set of orthogonal polynomials
Pn(x,n).  In particular of the form Pn(nx), regarding such fundamental
concepts as generating functions, weights, Rodriguez formulas, etc. I am
interested in Hermites and Laguerres specifically, but any info anyone

3 Orthogonal Polynomials and Random Matrices:  A Riemann-Hilbert Approach
Percy Deift
1999, 273 pp., $20, ISBN 0-9658703-2-4

These notes expand on a set of lectures at the Courant Institute in
1996-1997 on Riemann-Hilbert problems, orthogonal polynomials, and random
matrix theory. The main goal of the course was to prove universality for a
variety of statistical quantities arising in the theory of random matrix
models. The main ingredient in the proof is the steepest descent method
for oscillatory Riemann-Hilbert problems introduced earlier by the author
and Xin Zhou.

From: OP-SF Editor <muldoon@yorku.ca>
Subject: From the SIAM President  

Tom Koornwinder reminds me that our activities have gotten a couple of
boosts from Gilbert Strang in his column "From the SIAM President" in SIAM

In the March 1999 issue, Gilbert writes:
"...In addition to its own conferences and workshops, SIAM joins with
others in sponsoring conferences around the world.  A good one on special
functions is coming soon (June 21-25; www.cityu.edu.hk/ma) in Hong Kong. 
I have a greater respect than ever for special functions after
recent work with Alan Edelman - who was counting paths in a graph. 
We were looking for the eigenvalues of the graph's adjacency matrix A, and
path counts gave the diagonal entries in the powers of A.
The numbers that cane out were 4, 28, 232, 2092, 19864, ... and we
couldn't see a pattern. In desperation we sent them to
superseeker@research.att.com (a miracle program created by Neil Sloane).
To my amazement, superseeker returned a third-order recurrence (quite
complicated).  Doubting the whole thing, I insisted on sending the next
ten numbers in the sequence.  The exact same recursion came back in nine
seconds (with a generating function too, just what we needed).  MATLAB
produced the numbers, Maple simplified the recursion and Mathematica
identified the solution as a Jacobi polynomial.  Is this really
mathematics?  At least we got the answer (a special function, of course

In his April column, Professor Strang discusses (among other things)  the
importance of algorithms and later writes: 
"Our annual meeting in Atlanta includes a special minisymposium arranged
by the Activity Group on Orthogonal Polynomials and Special Functions
....with a strong program. You should contact poly-request@siam.org for
the mailings form this group. The whole subject of special functions is
important to SIAM - a complement (not orthogonal) to Algorithms. ..."

Thanks, Gilbert!
