Future plans:
* There are plans to organize summer schools on "Orthogonal Polynomials and
Special Functions" in Europe during the coming three years:
- 2001 (probably September): in Germany (contact person: Rupert Lasser
<lasser@gsf.de>)
- 2002 : in the Netherlands or Belgium (contact person: Erik Koelink
<koelink@dutiaw4.twi.tudelft.nl>
- 2003 (time undecided): in Portugal (contact person: Amilcar
Branquinho).
The coordinator of the three summer schools is Erik Koelink
(koelink@dutiaw4.twi.tudelft.nl). These summer schools are part of our
Activity Group's scientific program. The scientific committee consists of
Erik Koelink, Rupert Lasser, Amilcar Branquinho, Paco Marcellan and Walter
Van Assche.

Subject: Planned activities
1. SIAG OP-SF Summer Schools. The first of these was held at Laredo,
Spain, July 24-28, 2000. Three more are planned: September 2001 in
Germany, 2002 in Belgium, and 2003 in Portugal. Paco Marcellan and
Walter Van Assche, our Program Director and Vice Chair, are leading the
organizing committee for these events.
2. Sixth International Symposium on Orthogonal Polynomials, Special
Functions, and Applications (OPSFA), Rome, Italy, June 18-22, 2001. The
7-member organizing committee includes 3 SIAG members (De Bruin,
Marcellan, Muldoon). Of 8 invited speakers, 5 are SIAG members (Askey,
Dunkl, Suslov, Temme, Van Assche). All SIAG officers will be present at
this Symposium, and I plan to hold the 2001 officer's meeting there.
Also, if additional SIAG members plan to be in Rome, please let me know
in advance. If there are enough of us, it might be worthwhile to have
a general member's meeting in Rome.
3. SIAM Annual Meeting, July 9-13, 2001. We have decided not to sponsor a
minisymposium because recent annual meetings have not attracted our
membership or, indeed, our officers. There are a variety of reasons for
this, not least the existence each year of at least one meeting - and
usually more than one - on orthogonal polynomials and special functions in
the U.S. and abroad. Naturally, our members tend to use their limited
travel budgets to attend meetings that are closely connected with their
research. It doesn't help that our subject area has not been
well-represented on the plenary programs at recent SIAM meetings. I am
trying to open a dialog with SIAM about these problems. One idea is to
ask SIAM to appoint a representative of our SIAG to be on the organizing
committee for the 2002 annual meeting. This meeting will celebrate the
50th anniversary of SIAM in Philadelphia, the home city of SIAM. Another
idea is SIAM/SIAG co-sponsorship of non-SIAM meetings. I hope further
ideas will come from officers and members at the OPSFA meeting in Rome or
by email to me.

Subject: Request for information
As many of you know, NIST is doing a revision of the Handbook of
Mathematical Functions, now titled "The digital library of mathematical
functions". In addition to including important facts about many special
functions, there is a need to include references to uses of them. Each of
us knows some, but collectively we know much more. It would be useful to
the authors of the individual chapters if people sent examples of
important uses of the usual special functions and their properties.
Let me give an example of how an old handbook was used to suggest an
interesting property of Legendre polynomials, and then mention a use of
the inequalities which were suggested by one graph in Jahnke and Emde.
When Legendre polynomials are graphed on (-1,1) a number of things are
suggested. First, all the zeros lie in this interval. Second, the
polynomials are bounded by 1 in absolute value on this interval. Third, if
the absolute values of the successive extrema are considered, they
decrease when going from 1 to 0. All of these facts had been observed and
proved more than 100 years ago. About 55 years ago, John Todd looked
carefully at a graph consisting of P_n(x) on (0,1) for n=1,2,...7. He
noticed that the first minimum value of each of these functions when you
look back from 1 seems to be an increasing function of n, the first
maximum seems to be decreasing, and so on. These extrema have limits of
the extrema of the Bessel function J_0(x). In a few years a proof was
found by Gabor Szego, extended to ultraspherical polynomials suitably
normalized by Otto Szasz, and a similar result was found for Hermite
polynomials when suitably normalized. For many years these inequalities
sat there as beautiful results but without serious use.
The result for Legendre polynomials was rediscovered by Cornille and
Martin in some work on pi-pi scattering. They also found a different
weighted result for ultraspherical polynomials. Between the publication of
their first paper and their second, someone told them of Szego's work.
References are given in my SIAM regional conference lectures. It would
have helped Cornille and Martin if this result had been included in a book
they looked at. As we all know, results which are not eventually
published in a book are very likely to get lost. Also, users of special
functions will find it helpful to know the general areas in which these
functions are used. Finally, mathematicians need to know about the uses
of the functions since the users frequently need something just a little
bit different than what mathematicians have done.
There is another graph in Jahnke and Emde which was not looked at for
even longer. This is a graph of Q_n(x) on (0,1) for n=1,2,3,4,5. A
similar monotonicity result is suggested by this graph, and has been
proven. I don't know applications of it, but strongly suspect there will
be some.
I am writing the chapters on gamma and beta functions and on higher
hypergeometric series. Any references which can be sent about uses of
these functions would be helpful. I am sure that the other authors would
also find it useful to hear about applications of the functions they are
writing about. To avoid duplication, it would be best to send them to the
list opsftalk@nist.gov and Dan Lozier can forward them the author of the
chapter if necessary.
Thanks in advance for help.

Subject: opsftalk
After a quiet period, there has been here a recent spurt of activity in
opsftalk, the discussion group of our Activity Group.
Sergei Sadov asked whether certain formulas arising in matrices of
potentials in the Legendre basis were known. Richard Askey pointed out a
connection with work of Polya and Szego. George Gasper pointed out that
another formulas asked about by Sadov is equivalent to a known formula of
Whipple and Sadov forwarded further references sent to him by E. D.
Krupnikov. David Strozzi asked about the numerical computation of the
hypergeometric function bringing some responses and references from
Daniel Lozier and Nico Temme.
A remarkable aspect of these exchanges was the quick turnaround time.
Readers are encouraged to subscribe and sent their questions and comments

From: OP-SF NET Editor <muldoon@yorku.ca>
Subject: IMA Program on "Special Functions in the Digital Age"
The Institute for Mathematics and its Applications, Minneapolis,
Minnesota, USA, will host a summer Program "Special Functions in the
Digital Age" in the period July 22 - August 2, 2002.
The program is not yet open for registration and the schedule and list of
participants are not yet available. The following description is taken
form the web site: http://www.ima.umn.edu/digital-age/
Introduction:
Mathematical tables and handbooks have played a pivotal role in
applications and also the development of mathematics itself over the
centuries. Now, with the advent of the digital age, the traditional
handbook format has become obsolete, and a complete rethinking of the
nature and role of mathematical handbooks must be undertaken. The purpose
of this program is to formulate, though concrete examples and experiences,
the role and character of digital libraries in mathematics, and the
mathematical and applied fields that would benefit from such a library.
The first serious attempt to address these issues is the ongoing Digital
Library of Mathematical Functions (DLMF) project at the National Institute
of Standards and Technology (NIST). This workshop will take the DLMF
project as a basis for assessing both the state of the art in special
function theory, what aspects are of importance in applications,
particularly to chemistry and physics, and the experiences gained in this
project to formulate recommendations for how digital libraries of
mathematics should be organized, utilized, and developed. We also
anticipate the experiences of the DLMF project to provide insight and
recommendations for how mathematics should be stored and disseminated over
the internet.
Of the currently used handbooks, the most well-developed have been those
devoted to special functions and their applications. The principal
handbooks on special functions, "Higher Transcendental Functions" (the
Bateman Project) and the NIST (formerly National Bureau of Standards)
"Handbook of Mathematical Functions," are among the most useful, widely
consulted technical volumes ever published, but they are now out of date,
due to rapid research progress and revolutionary changes in technology.
(See http://www.siam.org/siamnews/03-98/function.htm for additional
information.) Using these as concrete examples of a mathematical digital
library, the program will assess recent progress in updating these
handbooks and recent advances in the theory and use of special functions,
and to point out the areas of research in special functions that hold the
most promise and importance for future development, both for theorists and
users. In the broader arena, the workshop will aim to use the experience
in this particular subject to generate recommendations for further digital
library projects in the mathematical sciences and their applications,
including, but not limited to, numerical analysis, group theory, signal
processing, statistics, linear algebra, partial differential equations,
and so on.
Description:
The IMA workshop will use the DLMF project as a foundation and discuss
what more should be done, what areas are incomplete or unrepresented, what
are the resulting mathematical, symbolic, numerical and web issues,
applications in physics, chemistry, etc., relationships with the Bateman
project, and potential for other digital libraries in other mathematical
areas. The workshop is to have a very broad outlook, encompassing a wide
range of subjects connected with special functions, as well as issues
concerning digital libraries and the delivery of mathematics over the
internet.
A major portion of this program (7 days) will be assessments of research
progress and promising vistas for future research by distinguished experts
in the areas of asymptotics, combinatorial functions, statistics, computer
algebra, algebraic and group theoretic methods, applications to the
physical sciences, orthogonal polynomials, numerical methods, zeta
functions & random matrices, Painlevé functions, elliptic functions,
elliptic hypergeometric functions and the Heun function group, with the
aim of pointing out what is of greatest importance in the theory and
applications, and what should be included in digital library projects.
The remainder of the program (3 days) will be devoted to Digital Libraries
generally and, specifically, Digital Libraries and the Mathematical
Sciences, including the delivery of mathematics over the Internet. It will
conclude with a panel on the "Future of Mathematical Digital Libraries,"
with panelists from the special functions research and users communities,
as well as representatives from mathematics societies and government
funding agencies.
There will be several discussion sessions to develop specific
recommendations for special function topics to be included in future
Digital Libraries in Mathematics. Also there will be poster sessions, and
several software demonstrations (particularly of computer algebra and
numerical packages for special functions), and much of the software will
be available during the program for informal use by participants. This
program will link with special function related sessions at the
Foundations of Computational Mathematics (FoCM'02) meeting that will be
hosted by the IMA, August 5-15, 2002.
The program is meant for researchers in the theory and computation of
special functions (definitely including people new to the field who are
looking for the most promising areas for future research), for users of
special functions, and for persons interested in the delivery of
mathematics over the Internet.

Subject: Report on AMADE-2001
International Conference "Analytical Methods of Analysis and Differential
Equations" (AMADE-2001), Minsk, Belarus, February 15-19, 2001
The international conference "Analytical Methods of Analysis and
Differential Equations" (AMADE-2001) took place February 15-19, 2001 in
Minsk, Belarus. It continues the series of the international conferences

Title: Orthogonal Polynomials of Several Variables
Authors: Dunkl, Charles and Xu, Yuan
April 2001, 400 Pages, Hardback, ISBN: 0-521-80043-9, $80.00
This is the first modern book on orthogonal polynomials of several
variables, which are valuable tools used in multivariate analysis,
including approximations and numerical integration. The book presents the
theory in elegant form and with modern concepts and notation. It
introduces the general theory and emphasizes the classical types of
orthogonal polynomials whose weight functions are supported on standard
domains such as the cube, the simplex, the sphere and the ball. It also
focuses on those of Gaussian type, for which fairly explicit formulae
exist. The authors' approach blends classical analysis and
symmetry-group-theoretic methods. The book will be welcomed by research
mathematicians and applied scientists, including applied mathematicians,
physicists, chemists and engineers.

Orthogonal Polynomial for Exponential Weights
CMS Books in Mathematics, Vol 4
2000. Approx. 350 pp. Hardcover $69.95 (tent.) ISBN 0-387-98941-2
The analysis of orthogonal polynomials associated with general weights has
been a major theme in classical analysis this century. The use of
potential theory since the early 1980's has had a dramatic influence on
the development of orthogonal polynomials associated with weights on the
real line. For many applications of orthogonal polynomials, for example in
approximation theory and numerical analysis, it is not asymptotics but
certain bounds that are most important.
In this monograph, the authors define and discuss their classes of
weights, state several of their results on Christoffel functions,
Bernstein inequalities, restricted range inequalities, and record their
bounds on the orthogonal polynomials as well as their asymptotic results.
This book will be of interest to researchers in approximation theory and
potential theory, as well as in some branches of engineering.

ABOUT THIS BOOK
The book offers an accessible reference for researchers in the
probability, statistics and special functions communities. It gives a
variety of interdisciplinary relations between the two main ingredients of
stochastic processes and orthogonal polynomials. It covers topics like
time dependent and asymptotic analysis for birth-death processes and
diffusions, martingale relations for Levy processes, stochastic integrals
and Stein's approximation method. Almost all well-known orthogonal
polynomials, which are brought together in the so-called Askey Scheme,
come into play. This volume clearly illustrates the powerful mathematical
role of orthogonal polynomials in the analysis of stochastic processes and

Topic #12 ------------ OP-SF NET 8.2 ---------------- March 15, 2001
~~~~~~~~~~~~~
From: OP-SF NET Editor <muldoon@yorku.ca>
Subject: Further information on the Hong Kong Proceedings
[This is from information sent by Charles Dunkl and Dan Lozier]
In connection with the Proceedings of the International Workshop on
Special Functions -- Asymptotics, Harmonic Analysis and Mathematical
Physics held June 21-25, 1999 at the City University of Hong Kong, the
following is the full bibliographic information to supplement our
announcement in OP-SF NET 7.6, Topic #5 :
Special Functions: Proceedings of the International Workshop, C. Dunkl, M.
Ismail, R. Wong, editors, 438 + xi pages, World Scientific (Singapore),
ISBN 981-02-4393-6, 2000.
There was a panel discussion at the Workshop, for which a summary was
written. This summary is mentioned in the preface to the Proceedings but
was omitted inadvertently. It can be seen at
http://math.nist.gov/opsf/books/hongkong99.html.
It appeared also in OPSF-NET 6.5, Topic # 7 (September 1999) and in the
printed Newsletter (vol. 10, no. 1, October 1999).
For further information about the Workshop, including photographs, see

Topic #13 ------------ OP-SF NET 8.2 ---------------- March 15, 2001
~~~~~~~~~~~~~
From: Wolfram Koepf <koepf@mathematik.uni-kassel.de>
Subject: Maple packages for hypergeometric summation
Updates of the Maple packages hsum.mpl and qsum.mpl for hypergeometric
summation and q-hypergeometric summation [see my book "Hypergeometric
Summation", Vieweg, Braunschweig, 1988, distributed in the North America
by the AMS, see http://www.ams.org/bookstore, reviewed in OP-SF NET 6.4
#12] can be obtained from the web page
http://www.mathematik.uni-kassel.de/~koepf/Publikationen.
The updates work now with Maple V and Maple 6, and the names of the
updated versions are hsum6.mpl and qsum6.mpl. They contain implementations
of Gosper's, Zeilberger's and Petkovsek's algorithms and their
corresponding q-versions.

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 Editor is Martin Muldoon (muldoon@yorku.ca).
To receive the OP-SF NET, send your name and email address to
poly-request@siam.org.
