Topic #1  ---------------  OP-SF NET  ---------------- January 18, 1996
From: Tom Koornwinder <thk@fwi.uva.nl>
Subject: Introducing this issue

In the year 1996 our Activity Group starts with a partially changed
team of officers, see Topic 2. I want to thank George Gasper and
Martin Muldoon, who have ended now their period as elected officers,
for the pleasant cooperation.  As for OP-SF Net, they have commented
many times on draft issues, suggested improvements and found errata.
Martin Muldoon will remain involved in our Activity Group as
Webmaster, managing our home page

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

on World Wide Web. Moreover, he has agreed to become, together with
me, an editor of OP-SF Net, starting with the next issue.

I also welcome the two new officers Bill Miller and
Nico Temme. I know them already for a very long time, and I am sure
they will have valuable inputs for our activities.

We are considering to make better use of World Wide Web for our
purposes. Possibly, back issues of OP-SF Net (and maybe the
Newsletter) will be integrated, marked up and hyperlinked so that you
can easily browse the Web for matters relevant to our field. Our plans
are still somewhat indefinite, but we recommend that you visit our
home pages regularly so as to keep abreast of new information as we
install it.

Finally, those with less sophisticated or no access to the internet
should not worry. The printed Newsletter and the e-mail version of
OP-SF Net will continue.

		Tom Koornwinder



Topic #2  ---------------  OP-SF NET  ---------------- January 18, 1996
From: Donna Blackmore <blackmore@siam.org>
Subject: SIAG/OS Election Results

(edited and shortened by OP-SF Net editor)

The results of the recent election for officers of the
SIAM Activity Group on Orthogonal Polynomials and Special
Functions are finalized.  The  newly-elected officers are:

               Chair               Charles F. Dunkl
               Vice Chair          Tom H. Koornwinder
               Secretary           Nico M. Temme
               Program Director    Willard Miller, Jr.

Each will be serving a three-year term beginning January 1, 1996.

Also, for your information, ca. 43% of the membership voted.  This
is extremely high. In the SIAM elections, usually about 20% vote.


Suggestions for Future Activities (selection):

 o Seminars on introductory research for post-graduate students.
 o Some activities in western European countries as well as in Latin
   America.
 o Please start discussions with SIAM about the possibility to
   start publication of monograph on orthogonal polynomials and
   special functions.
 o Sponsorship for new families of special functions and new sets
   of orthogonal polynomials.
 o Define a program of self study for the non-mathematician, i.e.,
   for an engineer mathematically inclined that uses OP and SF.  In
   others words, could the group indicate a limited set of books and
   papers (including survey paper) that could give an adequate basis
   to understand survey papers that would give the current trends
   and needs in OP-SF.



Topic #3  ---------------  OP-SF NET  ---------------- January 18, 1996
From: Wolfram Koepf <koepf@zib-Berlin.de>
Subject: Obtaining back issues of the Newsletter in electronic form

The officers of the Activity Group have decided to give public access
to back issues of the printed Newsletter in electronic form. At the
time of their appearance, new issues of the Newsletter will not be
accessible electronically since it should be the privilege of the
members of the Activity Group to receive them. However, as an
additional benefit to any interested person, previous issues can
now be obtained as dvi or PostScript files from my WWW homepage:

    http://www.zib-berlin.de/~bzfkoepf/

or by anonymous ftp at

   ftp.zib-berlin.de   in directory   pub/UserHome/Koepf/SIAM

You probably will prefer to receive the dvi files since these are
much smaller in size, because they do not include the logo.
Note that the WWW address of my homepage has changed!



Topic #4  ---------------  OP-SF NET  ---------------- January 18, 1996
From: Tom Koornwinder <thk@fwi.uva.nl>
Subject: 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".

Our Activity Group probably will not sponsor or organize any
Minisymposium during this Annual Meeting. Our Program Director Martin
Muldoon (who was in office until December 1995) has explored several
options for topics, but all failed for some reason. In particular, the
idea of organizing a Minisymposium on "Handbooks of Special Functions"
(see OP-SF Net 2.6, topic 2) could not be realized, because some of
the key lecturers on such a topic already had commitments for a
conference ICCAM 95, which will be held in Leuven, Belgium in the same
week (see topic #12).  Hopefully our Activity Group can organize a
Minisymposium with this theme on a later occasion.

Topic #16  --------------  OP-SF NET  ---------------- January 18, 1996
From: Tom Koornwinder <thk@fwi.uva.nl>
Subject: Askey-Wilson computer algebra mini-project

During the period January-June 1996 Rene Swarttouw is working at
RIACA, Eindhoven, The Netherlands  on a project "A computer implementation
of the Askey-Wilson scheme". This project was proposed by Tom Koornwinder.
The purpose of the project is to make a start with bringing the report

 R. Koekoek and R.F. Swarttouw,
 The Askey-scheme of hypergeometric orthogonal polynomials and its
 q-analogue,
 Report 94-05, Delft University of Technology, Faculty TWI, 1994.

to the form of an interactive book, with facilities for symbolic
manipulation of formulas.

Further information at Tom Koornwinder <thk@fwi.uva.nl> or
Rene Swarttouw <renes@can.nl>.

By the way, the Delft TWI Report 94-05 mentioned above can now be
electronically retrieved by ftp:

  ftp ftp.twi.tudelft.nl
  cd TWI/publications/tech-reports/1994
  binary
  get DUT-TWI-94-05.ps.gz

which can also be reached by:

WWW: ftp://ftp.twi.tudelft.nl/TWI/publications/tech-reports/1994/

You will thus obtain the compressed postscript file of the original
hardcopy version. Later errata (see OP-SF Net 2.2, topic 7) are not yet
incorporated.



Topic #17  --------------  OP-SF NET  ---------------- January 18, 1996
From: OP-SF Net editor <thk@fwi.uva.nl>
Subject: Research Problems Section of Constructive Approximation on WWW

The journal Constructive Approximation has started on its WWW home page

    http://www.math.usf.edu/CA/index.html

a Research Problems section, edited by Peter Borwein, Ingrid Daubechies
and Vilmos Totik.

The Research Problems section will publish open problems. Ideally,
these problems are easy to state, substantial but not impossible, and
of wide appeal.  Problems need not be new.

Manuscripts should be between one and four tex pages. Enough
references should be included that the reader can access the recent
literature. All submissions will be refereed and reprints will be
supplied. Solutions will not, as a matter of course, be published in
Constructive Approximation.

Submissions for the Research Problems section should be made
electronically to Research_Problems@cecm.sfu.ca in any standard
version of Tex or Latex or by using the Constructive Approximation
macros (Please avoid using unusual macros or style files). Queries may
also be directed to the above address.

Topic #20  --------------  OP-SF NET  ---------------- January 18, 1996
From: OP-SF Net Editor <thk@fwi.uva.nl>
Subject: Haubold's preprint archive

See OP-SF Net 2.6, topic 3 for the announcement of Hans Haubold's
preprint archive. This archive 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 of the ftp site. Note
also that, in addition to the directory   opsf   with files of full
papers, a directory called   abstracts   has been created with abstract
files of papers which can be electronically retrieved from elsewhere.

Since November 6, 1995 several new files were deposited in the
"siam/submissions" directory. These are not yet documented in
the file 00contents.ftpsite


Topic #21  --------------  OP-SF NET  ---------------- January 18, 1996
