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:

ftp.fwi.uva.nl/pub/mathematics/reports/Analysis/koornwinder/opsfnet.dir

or (generally faster in North America) from:

http://www.math.ohio-state.edu/JAT/DATA/OPSFNET/opsfnet.html

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

http://www.math.yorku.ca/Who/Faculty/Muldoon/siamopsf/

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

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
organizers.

- 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 submission. 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. If you have any questions, please contact: Allison G. Bogardo, SIAM, 3600 University City Science Center, Philadelphia, PA 19104-2688; telephone: (215) 382-9800; e-mail to bogardo@siam.org; fax to (215) 386-7999.

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 participate. 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. Contents: 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) Bibliography Notations and Symbols Index 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. Topic #11 ---------------- OP-SF NET ----------------- March 14, 1996 From: R. Koekoek <koekoek@twi.tudelft.nl> Subject: Koekoek-Swarttouw report on Askey-scheme The report R. Koekoek and R.F. Swarttouw, The Askey-scheme of hypergeometric orthogonal polynomials and its q-analogue, Faculty of Technical Mathematics and Informatics, Delft University of Technology, Report 94-05, 1994; can now be retrieved electronically from Haubold's ftp site unvie6.un.or.at, directory siam/opsf/koekoek_swarttouw, or via WWW from: ftp://unvie6.un.or.at/siam/opsf/koekoek_swarttouw/ The directory contains the following files: - readme : the information given in this item - as_info.ps : PostScript-file with information - errata.ps : PostScript-file of the list of errata (February, 1996) - AskeyWilson.ps : PostScript-file of the latest version (February, 1996) So if you have a hardcopy of the original version (the above mentioned report) you can download the files as_info.ps and errata.ps in order to read the information and get the list of errata. Otherwise you can download the file AskeyWilson.ps instead of errata.ps to get the latest version (121 pages) of the report. The file AskeyWilson.ps is also available in compressed form at two different ftp sites (use binary mode for transmission): unvie6.un.or.at, directory siam/submissions, file AskeyWilson.ps.Z ftp.fwi.uva.nl, directory pub/mathematics/reports/Analysis/aboutothers, file AskeyWilson.ps.gz Topic #12 ---------------- OP-SF NET ----------------- March 14, 1996 ~~~~~~~~~ We would like to propose the following problem: Can the infinite series $$\sum\limits_{n=1}^{\infty}\frac{x^n}{n!}\ln(n+\alpha)$$ be expressed in terms of known functions and constants? We do not know any solution of the problem and will be thankful for any comments, suggestions, solutions, etc. Victor Alexandrov & Rafail Krichevskii alex@math.nsk.su Topic #13 ---------------- OP-SF NET ----------------- March 14, 1996 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: approx@mi.uni-erlangen.de schmid@mi.uni-erlangen.de strauss@am.uni-erlangen.de 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 to at-net@mi.uni-erlangen.de and to get a list of subscribers, send the message: review at-net also to: at-net@mi.uni-erlangen.de 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: http://www.mi.uni-erlangen.de/~approx Topic #15 ---------------- OP-SF NET ----------------- March 14, 1996 From: Paul Nevai <nevai@ops.mps.ohio-state.edu> (revised by editors) 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 http://www.math.ohio-state.edu/JAT or http://www.math.ohio-state.edu/JAT/DATA/wjat.html 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 #16 ---------------- OP-SF NET ----------------- March 14, 1996 From: OP-SF Net editor <thk@fwi.uva.nl> Subject: WWW and ftp addresses A more comprehensive list of ftp and WWW addresses relevant for our field is available at the home page of the Activity Group WWW: http://www.math.yorku.ca/Who/Faculty/Muldoon/siamopsf/ under "Links to WWW pages of interest to members" This list will be regularly updated, and the changes will be mentioned in OP-SF Net.
