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 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 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 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 #5 --------------- OP-SF NET ---------------- January 18, 1996 ~~~~~~~~~ From: Walter Van Assche Subject: One-day meeting in Leuven on Special functions etc. Special Functions and their Applications Thursday February 1, 1996 Katholieke Universiteit Leuven Campus Arenberg III Celestijnenlaan 200 Heverlee (Leuven), Belgium You are cordially invited to attend a one day meeting on "Special functions, Orthogonal polynomials and rational approximation" in honour of Andre Ronveaux, who retired in September 1995 from the Facultes Universitaires Notre Dame de la Paix, Namur.

Topic #16 -------------- OP-SF NET ---------------- January 18, 1996 ~~~~~~~~~ From: Tom Koornwinder 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 or Rene Swarttouw . 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 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 #18 -------------- OP-SF NET ---------------- January 18, 1996 ~~~~~~~~~ From: OP-SF Net editor 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 "List of WWW pages of interest to members" This list will be regularly updated, and the changes will be mentioned in OP-SF Net.
