See the obituary notice at http://web.mit.edu/newsoffice/nr/1999/rota.html 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. Charles F. Dunkl Secretary SIAG/OS Topic #3 ------------- OP-SF NET 6.3 ------------- May 15, 1999 ~~~~~~~~~~~~~ From: Renato Alvarez-Nodarse 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 http://math.unm.edu/ACA/1999.html}. 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 #4 ------------- OP-SF NET 6.3 ------------- May 15, 1999 ~~~~~~~~~~~~~ From: OP-SF NET Editor <muldoon@yorku.ca> Subject: Workshop on Symbolic and Numerical Scientific Computation [The following information is from the web site: http://www.risc.uni-linz.ac.at/conferences/summer99/snsc99.html] Workshop on Symbolic and Numerical Scientific Computation (SNSC'99) Johannes Kepler Universität Linz, Austria August 18 - 20, 1999 SNSC'99 is an open workshop of the SFB (special research initiative) "Numerical and Symbolic Scientific Computation". The goal of this workshop is to further the integration of methods in symbolic and numerical scientific computation. In addition to presentations by members of the SFB, several invited speakers will explain their approach to the integration of these two scientific fields. The following invited speakers are already confirmed: C. Bajaj (Univ. Texas at Austin, USA), K.O. Geddes (Univ. Waterloo, Canada), V. Gerdt (JINR Dubna, Russia), E.

Topic #5 ------------- OP-SF NET 6.3 ------------- May 15, 1999 ~~~~~~~~~~~~~ From: Arno Kuijlaars <Arno.KUIJLAARS@wis.kuleuven.ac.be> Subject: Hong Kong Workshop on Minimal Energy Problems A workshop on Minimal Energy Problems will be held from November 8-12, 1999, at the City University of Hong Kong, as part of a series of Foundations of Computational Mathematics workshops to be held this fall. The meeting will emphasize research work related to distributing points on a sphere and on general Riemann surfaces, discrepancy results (e.g. for Fekete points), potential theoretic tools and applications to orthogonal polynomials, random matrices, integrable systems, etc. For further information, contact Ed Saff (esaff@math.usf.edu) or Arno Kuijlaars (arno@wis.kuleuven.ac.be), or consult the workshop home page http://www.math.usf.edu/FoCM99 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.

I only forward this message! V.Z. From: Tom Hoovler <bx238@freenet.buffalo.edu> Subject: Orthogonal polynomials with order-dependent argument 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 could give me regarding this, I would be interested. Topic #8 ------------- OP-SF NET 6.3 ------------- May 15, 1999 ~~~~~~~~~~~~~ From: Vadim Zelenkov <zelenkov@isir.minsk.by> Subject: Lecture Notes on Orthogonal Polynomials and Random Matrices [Editor's Note: This appeared on opsftalk; it was forwarded from the newsgroup sci.math.research.] Subject: Courant Institute Lecture Notes series This is to advise newsgroup readers of the availability of the new series published by the Courant Institute. Numbers 1,2,3 are available now; numbers 4 and 5 are forthcoming. More details, and a secure server for orders can be viewed at http://www.cims.nyu.edu/lecnotes .... 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. Topic #9 ------------- OP-SF NET 6.3 ------------- May 15, 1999 ~~~~~~~~~~~~~ From: Tom Koornwinder <thk@wins.uva.nl> Subject: opsftalk listserv taken over by Dan Lozier Up to now the listserv opstalk has been supervised and moderated by me at the University of Amsterdam via a majordomo program. It is a service of the SIAM Activity Group on Orthogonal Polynomials and Special Functions. >From now on this service will be continued by Dan Lozier (email dlozier@nist.gov). Dan has copied the present mailing list, so no action by subscribers is required, unless they want to unsubscribe. All information about opsftalk can now be found in http://math.nist.gov/opsftalk/ This information includes the following: To subscribe to OPSF-Talk, send a message to listproc@nist.gov with subscribe opsftalk xxxxx on a single line in the message body, where in place of xxxxx you put your name. To cancel your subscription, send "unsubscribe opsftalk" to the same address. You can post messages by sending mail to opsftalk@nist.gov. Your message will be forwarded to the moderator, who will usually pass it to everybody on the opsftalk list. It will also be added automatically to an archive. You can see all opsftalk messages (going back to January 1998) in http://www.nist.gov/itl/div896/emaildir/opsftalk/maillist.html The archive of postings to opsftalk at http://www.findmail.com/listsaver/opsftalk/ will no longer be updated, and will probably soon be removed completely. I am grateful to Dan that he is willing to continue this. I think a listserv like this can potentially be a valuable medium for providing and getting information, posing questions and discussing topics which are of immediate interest for our specialism. To be honest, during the first 15 or 16 months of its existence, postings were not yet up to my expectations. Topic #10 ------------- OP-SF NET 6.3 ------------- May 15, 1999 ~~~~~~~~~~~~~ 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 News. 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. ..."
