Topic #1  ----------------  OP-SF NET  ----------------- March 14, 1996
From: Charles Dunkl <cfd5z@virginia.edu>
Subject: Appointments

Wolfram Koepf has accepted an appointment as Editor of the (printed)
Newsletter of the Activity Group for the period Jan 1996 to Dec 1998.
Martin Muldoon has accepted an appointment for the same period as
Webmaster and co-editor of OP-SF NET.  On behalf of the elected officers,
I express our appreciation to Martin and Wolfram, and we look forward to
continuing to work together with them in the Activity Group.

Topic #2  ----------------  OP-SF NET  ----------------- March 14, 1996
From: Martin Muldoon <muldoon@mathstat.yorku.ca>
Subject: OP-SF WEB

This Newsletter (including back issues)  is available in two places on the
World Wide Web, either from Tom Koornwinder's archive:


or (generally faster in North America) from:


an archive maintained by Paul Nevai. (Indeed, with lynx, you can use
Paul's "wjat" (see Topic #15) to search the archive.)

But we have also started OP-SF WEB, a version of OP-SF NET designed for
World Wide Web browsing.  You can link to it from our Home Page:


At present, it has a number of headings:
              Conference Calendar
              Books, etc.
              Meeting Reports
              Personal, Obituaries, etc.

and more will be added.  Much of the information is the same as what you
read here in OP-SF NET.  But the WWW format offers a number of advantages:

        - Links can be added to other resources on the Web. So,
        for example, whenever possible, an announcement of a forthcoming
        meeting includes a link to the Web location maintained by the

        - Meeting reports can be supplemented by links to related
        information, abstracts, photographs, etc.

        - Information can be posted soon after it is received (generally
        within 24 hours).

Of course, OP-SF NET and the printed Newsletter will continue to be
provided, and information submitted to them will be considered for
inclusion in OP-SF WEB.

Topic #3   ----------------  OP-SF NET  ----------------- March 14, 1996
From: Willard Miller, Jr. <miller@ima.umn.edu>
Subject: Minisymposium at SIAM Annual Meeting in Kansas City

The 1996 SIAM Annual Meeting will be held on July 22-26, 1996
in Kansas City, Missouri, USA. See

WWW: http://www.siam.org/meetings/an96/an96home.htm

for further information, or send an email to meetings@siam.org .
A major theme is "New Tools of Applied Mathematics".
Carl de Boor will receive the von Neumann prize at this meeting.

In OP-SF Net 3.1, Topic #4 we wrote that our Activity Group probably
would not sponsor or organize any Minisymposium during this Annual
Meeting.  Fortunately, some proposal has still come up:

The SIAM Activity Group on Orthogonal Polynomials and Special Functions
will present a Minisymposium on Modern Topics in Orthogonal Systems.
(There are expected to be 4-6 speakers.) The Minisymposium will feature
two main topics: 1) Wavelets, organized by Gilbert G. Walter of the
University of Wisconsin, Milwaukee and 2) Multivariate Orthogonal
Polynomials that generalize Jacobi Polynomials, organized by Robert
Gustafson of Texas A&M University. (Both Walter and Gustafson will speak.
The wavelet topic will involve approximation theory issues and should be
closest to DeBoor's work.)

Topic #4  ----------------  OP-SF NET  ----------------- March 14, 1996
From: Allison Bogardo <bogardo@siam.org>
Subject: SIAM Student Paper Prizes

The annual SIAM Student Paper Prizes will be awarded during the 1996
SIAM Annual Meeting.

If you are a student or know of a student who would like to take part
in the competition, here are the details:

The authors of the three best papers in applied and computational
mathematics written by students and submitted to SIAM will be invited
to attend the 1996 annual meeting in Kansas City, Missouri, July
22-26.  Each winner must present his/her paper at the meeting and will
receive a $750 cash award as well as gratis registration for the
meeting.  Winners will be awarded calligraphed certificates at a
special prize ceremony at the meeting.  Papers must be singly authored
and not previously published or submitted for publication to be
eligible for consideration.  To qualify, authors must be students in
good standing who have not received their PhDs at the time of

In submitting their work for publication, authors are asked to
consider SIAM journals.

Submissions must be received by SIAM on or before March 15, 1996.

Submissions, which must be in English, can be sent by regular mail or
fax.  Each submission must include (1) an extended abstract NOT LONGER
THAN 5 PAGES (including bibliography); (2) the complete paper, which
will be used solely for clarification of any questions; (3) a
statement by the student's faculty advisor that the paper has been
prepared by the author indicated and that the author is a student in
good standing; (4) a letter by the student's faculty advisor
describing and evaluating the paper's contribution; and (5) a short
biography of the student.

Submissions will be judged on originality, significance, and quality
of exposition.

The winners will be notified by June 10, 1996.

Topic #8   ----------------  OP-SF NET  ----------------- March 14, 1996
From: Lisa Lorentzen <lisa@imf.unit.no>
Subject: meeting on Continued Fractions and Geometric Function Theory

Haakon Waadeland celebrates his 70th birthday on 20 May 1997. He is
responsible for a long list of valuable contributions to the two fields of
continued fractions and geometric function theory, and he is still very
active. In recognition of his work we have decided to organize a
conference in his honour.  The conference will be held in Trondheim,
Norway from 24 to 28 June 1997 under the title Continued Fractions and
Geometric Function Theory. We hope to get together a group of people
representing both fields, and we would very much appreciate if you would

You are all welcome to present talks of 25 minutes + 5 minutes for
questions. (If somebody has material suited for longer or shorter
presentations, we may be able to arrange this.)

We plan to publish proceedings from the conference.

The conference has its own world wide web page on
http://www.matstat.unit.no/CFGT, where we will put new information
when it is available. From this page you can also link to pages about
Trondheim and about the university, NTNU.

If you want to receive the second announcement, please give a YES
by e-mail to the conference address: confun@imf.unit.no
before 31 May 1996.

                                  With kind regards,
                       Lisa Lorentzen, Olav Njastad, Frode Ronning

Topic #9  ----------------  OP-SF NET  ----------------- March 14, 1996
From: Tom Koornwinder <thk@fwi.uva.nl>
Subject: new book

The following book appeared:

L.C. Biedenharn and M.A. Lohe,
Quantum group symmetry and q-tensor algebras,
World Scientific, 1995, x+293 pp.

The aim of the monograph is to develop and extend to quantum groups the
symmetry techniques familiar from the application of classical groups to
models in physics. The authors have taken a uniform approach to quantum
groups based on the fundamental concept of a tensor operator.

The book contains some results about q-special functions in connection with
quantum groups: in particular on q-analogues of Clebsch-Gordan coefficients
and Racah coefficients, and about q-hypergeometric functions in
connection with induced representations of the quantized universal
enveloping algebra for U(3).

Topic #10  ----------------  OP-SF NET  ----------------- March 14, 1996
From: Martin Muldoon <muldoon@mathstat.yorku.ca>
Subject: New book on special functions

Nico M. Temme, Special Functions: an Introduction to the Classical
Special Functions of Mathematical Physics, Wiley,
New York-Chichester-Brisbane-Toronto-Singapore, 1996, xii + 374 pp,
ISBN 0-471-11313-1.

1. Bernoulli, Euler and Stirling Numbers
2. Useful Methods and Techniques (Theorems from Analysis, Asymptotic
        Expansions of Integrals)
3. The Gamma Function
4. Differential Equations (Separating the Wave Equation, DE's in the
        Complex Plane, Sturm's Comparison Theorem, Integrals as Solutions,
        Liouville Transformation)
5. Hypergeometric Functions (includes very brief introduction to q-functions)
6. Orthogonal Polynomials
7. Confluent Hypergeometric Functions (includes many special cases)
8. Legendre Functions
9, Bessel Functions
10. Separating the Wave Equation
11. Special Statistical Distribution Functions (Error functions, Incomplete
Gammma Functions, Incomplete Beta Functions, Non-Central Chi-Squared
Distribution, Incomplete Bessel Function)
12. Elliptic Integrals and Elliptic Functions
13. Numerical Aspects of Special Functions (mainly recurrence relations)
Notations and Symbols

The author mentions that part of the material was collected from
well-known books such as those by Hochstadt, Lebedev, Olver, Rainville,
Szego, and Whittaker & Watson as well as lecture notes by Lauwerier and
Boersma.  But there is much recent material, especially in the areas of
asymptotic expansions and numerical aspects.  About half of the
approximately 200 references are dated 1975 and later.

The author states that the book "has been written with students of
mathematics, physics and engineering in mind, and also researchers in
these areas who meet special functions in their work, and for whom the
results are too scattered in the general literature." Complex analysis
(especially contour integration) would appear to be the main prerequisite.
The book is clearly written, with good motivating examples and exercises.
For example, the first chapter opens with a remarkable example of Borwein,
Borwein and Dilcher (Amer. Math. Monthly 96 (1989), 681-687 which
explains, using Euler numbers and Boole's summation formula, why the sum
of 50 000 terms of the very slowly converging alternating series for Pi/4,
though it gives an answer correct to only six digits, yet has nearly all
its first 50 digits correct.

From: OP-SF Net editor <thk@fwi.uva.nl>
Subject: open positions

K. Mimachi <mimachi@math.kyushu-u.ac.jp> informed me about approximately five
open positions at the assistant level (tenured) at the
Graduate School of Mathematics of  the Kyushu University (Fukuoka, Japan).

J. Charris <demat125@ciencias.campus.unal.edu.co> informed me about
two open tenure-track positions in mathematics at Universidad de Antioquia,
Medellin, Colombia.

Since these positions are open for mathematicians of all kinds of
specialization, not necessarily in Orthogonal polynomials and Special
functions, I will not give any details here, but just recommend interested
people to contact the email addresses mentioned above.

Topic #14  ----------------  OP-SF NET  ----------------- March 14, 1996
From: Editors of AT-NET <at-net@math.technion.ac.il>
Subject: Change of address for AT-NET

As of the next issue, AT-NET is changing its address. It will be run
from the University of Erlangen in Erlangen, Germany. The two new editors
who will be handling AT-NET are Hans-Joachim Schmid and Hans Strauss.

Submissions to At-Net should now be sent to one of:

The same listproc program which runs At-Net at its present address will
also run AT-NET at its future address, and thus the same commands should
work. Thus to sign on to AT-NET one should send the message:
       sub at-net first_name last_name

and to get a list of subscribers, send the message:
          review at-net
also to:

Current subscribers of AT-NET need NOT subscribe to the new address.
This will, of course, be automatically done.

A new home page with back issues of AT-NET may be found at:

Subject: searching aid for JAT home page

The home page of the Journal of Approximation Theory contains various
valuable databases. These can now be searched in a quick and efficient
way from your Unix shell, provided you have available the program lynx.
Just get the shell script "wjat" from



and easily install it in your private directory. Type   wjat -h
to learn about the various flags with which wjat can be used.

Paul Nevai adds:
Get "wjat" the jack-of-all-trades lynx interface to the databases of
Journal of Approximation Theory (JAT), with support of Constructive
Approximation (CA), East Journal on Approximations (EJA), Mathematical
Reviews (MR), Spline Bibliography Database (SPD), and (much) more. This
will be the smartest investment you have ever made or your money back.
-From the editors: You can use "wjat -O" to search back issues of OP-SF NET.

Topic #18  ----------------  OP-SF NET  ----------------- March 14, 1996
From: OP-SF Net editor <thk@fwi.uva.nl>
Subject: ftp site for papers in Orthogonal Polynomials and Special Functions

Hans Haubold's ftp archive for preprints in the area of Orthogonal
Polynomials and Special functions is the continuation of Waleed
Al-Salam's preprint archive.  One can approach the archive by
anonymous ftp to unvie6.un.or.at, directory siam, or at the WWW
address ftp://unvie6.un.or.at/siam .  See the file 00contents.ftpsite
in the submissions directory for the contents (titles, authors,
filenames) of the directories opsf and abstracts.  This list of
contents is in chronological order of submission.  The most recent
contributions will just reside as files in the submissions directory,
and are not yet documented in the list of contents.

Hans Haubold is sending regular info about new submissions to a large
mailing list. Please contact him <haubold@Relay1.Austria.EU.net>
if you want to be added to this mailing list or if your email address
on the list is no longer correct.

Between 4 December 1995 and 27 February 1996, the following
papers were submitted:

M.A. Pinsky, Speed of convergence of two-dimensional Fourier
integrals. (see siam/opsf/pinsky.tex).

M.S. Dijkhuizen, Some remarks on the construction of quantum
symmetric spaces. (see siam/opsf/dijkhuizen1.tex).

G. Olshanski and A. Vershik, Ergodic unitarily invariant measures
on the space of infinite Hermitian matrices. (see siam/opsf/olsh-

M. Alfaro, F. Marcellan, and M.L. Rezola, Estimates for
Jacobi-Sobolev type orthogonal polynomials.

R. W Koekoek and R.F. Swarttouw, The Askey-scheme of
hypergeometric orthogonal polynomials and its q-analogue.
(directory siam/opsf/koekoek_swarttouw, files readme, as_info.ps, errata.ps,
The file AskeyWilson.ps is also available in compressed form in the
directory siam/submissions as file AskeyWilson.ps.Z
