Topic #1   --------------   OP-SF NET 4.3  ------------- May 15, 1997
From: Charles Dunkl <cfd5z@virginia.edu>
Subject: Reciprocity arrangements

There has been discussion among the Activity Group officers and the
leadership of SIAM regarding reciprocity arrangements. Specifically we are
studying the feasibility of permitting membership in this activity group
to people who are not members of SIAM but are members of professional
societies which have a reciprocity arrangement with SIAM; this may mean a
limited membership at reduced rate, with corresponding reduction in
privileges such as receiving the SIAM Review. Possibly this hypothetical
arrangement would involve associate status and somewhat increased dues to
pay for the printing and postage charges, which are somewhat subsidized by
SIAM dues.  The main benefit would be the subscription to the printed
Newsletter, which currently appears three times a year. Now we address
this question to the readers of this electronic newsletter who are not
SIAM members:  would you be interested in such an arrangement? is your
professional society willing to participate?  If yes, please send e-mail
messages to us; this information can help us in discussions with SIAM
officers. Please answer before the end of June so we can prepare for the
coming annual SIAM meeting in July.

Topic #3   --------------  OP-SF NET 4.3 --------------- May 15, 1997
From: Wolfram Koepf <koepf@zib.de>
Subject: Updated information on Orthogonal Polynomials session at First
     ISAAC Conference

The First ISAAC (International Society for Analysis, its Applications and
Computation)to be held in Newark, Delaware, USA, June 3-7, 1997 was
announced in OP-SF NET 4.1 Topic #2.  Here we give updated information,
especially on the Section on Orthogonal Polynomials.

The Conference Secretary is

     Pam Irwin
     Department of Mathematics
     University of Delaware
     email: irwin@math.udel.edu

There is an online registration form available.

Session 13 of this conference will be devoted to Orthogonal Polynomials,
organized by Wolfram Koepf.  The emphasis of this session will be on the
use of symbolic computation in connection with orthogonal polynomials and
special functions. Symbolic computation has the potential to change the
daily work of everybody who uses orthogonal polynomials or special
functions in research or applications. It is the purpose of the proposed
section to bring together developers of symbolic algorithms and
implementations which are connected with orthogonal polynomials and
special functions with users of computer algebra systems who need this
type of software.

Note that Wolfram Koepf will present a Plenary Lecture at the Conference
on Orthogonal Polynomials and Computer Algebra, scheduled on Friday, June
6, 8.45.

Topic #10 --------------   OP-SF NET 4.3  ------------- May 15,1997
From: OP-SF Net editor <thk@wins.uva.nl>
Subject: New book on computation of special functions

S. Zhang and J. Jin,
Computation of special functions
Wiley, 1996
ISBN 0-471-11963-6

>From Professor Jin's web site
(http://iris-lee3.ece.uiuc.edu/~jjin/specfunc.html):

"The computation of special functions is a fundamental aspect of numerical
analysis in virtually all areas of engineering and the physical sciences.
Because most of these special functions are in the form of infinite series
or infinite integrals, their solutions are quite complicated. Fortunately,
the difficulty has been lessened considerably by the advent of powerful
personal computer hardware and software. Yet, until now, there has been no
single-source reference offering comprehensive coverage of the automated
computation of special functions.

"Computation of Special Functions is a valuable book/software package
containing more than 100 original computer programs for the computation of
most special functions currently in use. These include many functions
commonly omitted from available software packages, such as the Bessel and
modified Bessel functions, the Mathieu and modified Mathieu functions,
parabolic cylinder functions, and various prolate and oblate spheroidal
wave functions. Also, unlike most software packages, this book/disk set
gives readers the latitude to modify programs according to special demands
of the sophisticated problems they are working on. The authors provide
detailed descriptions of the programs algorithms as well as specific
information about each program's internal structure.

"To facilitate quick reference, each chapter follows the same, three-part
format. The first part covers major properties and important formulas
needed for computation. The second part of each chapter contains a
description of the algorithm or algorithms at the heart of the FORTRAN-77
program in question, and in the third part, the authors tabulate
representative results to provide an at-a-glance understanding of the
function's behavior as well as a valuable data-check for their computed
results.

"Computation of Special Functions is an indispensable tool for engineers
and physical scientists as well as students involved in advanced research
in these fields.

Topic #11  --------------  OP-SF NET 4.3 --------------- May 15, 1997
From: OP-SF Net editor <thk@wins.uva.nl>
Subject: SIAM Review

In OP-SF Net 4.2, Topic #11 we mentioned the possible ending of the
problem session in SIAM Review, and we added comments by several people.
The recent issue Vol. 39, Number 1 of SIAM Review opens with an item
"Changes planned for SIAM Review". Beginning in 1999 SIAM Review will
consist of five sections:

- Survey and Review
- Problems and Techniques
- Selected papers from SIAM's research journals
- Education
- Book reviews

No problem session is mentioned. The second section, where you might
suspect a problem session, will consist of papers.  These plans seem to be
definite. The blueprint was approved by SIAM's council and Board of
Trustees in July 1996. Questions about the new content or structure of
SIAM Review can be addressed to Mary Rose Muccie, SIAM Editorial Director
(email muccie@siam.org).

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.  Very recently, Hans Haubold has
constructed a convenient WWW interface for this ftp site, at the address

   ftp://unvie6.un.or.at/siam/opsf_new/00index.html

This home page links to pages
- Index by Author (with links to the actual manuscript files)
- Abstracts listed by Author(s) (mostly with abstracts of papers for which
   the full manuscript file resides elsewhere; hyperlinks are provided)
- Submission form

You can also move from the home page to the ftp interface and to the the
submissions directory, where the most recent contributions reside.

The WWW interface is beautifully done. We recommend that you visit it.

There are two new features in connection with submitting manuscripts
to the ftp site:

- If you submit a file with a full manuscript, it is recommended (though
  not obligatory) to also supply an abstract file (plain ASCII text, no
    TeX).

- It is also possible to submit only an abstract file together with a
  hyperlink to the actual full manuscript. In this case, please supply
  the hyperlink in the "Comments" Text-Area, when filling out the
  submission form.

Hans Haubold is sending regular information 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.

Since March 15, 1997 the following papers have been submitted to the
archive:

J.V. Stokman and T.H. Koornwinder, On some limit cases of Askey-Wilson
polynomials.
(see siam/submissions/classicalAWlimit.abstract).
