Dick Askey and Willard Miller are co-organizers. The principal handbooks on special functions, the "Bateman Project" and the NIST "Handbook of Mathematical Functions" are among the most useful, widely consulted technical volumes ever published, but they are now out of date, due to rapid research progress and to revolutionary changes in technology. The Minisymposium will feature talks by representatives of the groups that are proposing to update the Bateman Project and Abramowitz & Stegun, respectively, and talks with critiques of those CD-Rom and WWW handbook projects that are already available. The Minisymposium will conclude with a general discussion concerning the appropriate format and structure for handbook projects, and funding possibilities. The speakers will include Mourad Ismail, Dan Lozier and Dick Askey, among others. Willard Miller, Jr. Topic #2 -------------- OP-SF NET 4.1 -------------- January 15, 1997 ~~~~~~~~~~~~~ From: Wolfram Koepf Subject: First ISAAC Conference, Delaware, June 1997 Dear Colleagues: As you already know (see OP-SF Net 3.5, Topic #3), I am organizing Session 13 on "Orthogonal Polynomials" at the First ISAAC Conference, University of Delaware, Newark, Delaware, June 3-7, 1997. Note that the conference is scheduled one day later than originally stated to enable the participants to get cheap flights. The emphasis of this session will be on the use of symbolic computation in connection with orthogonal polynomials and special functions. 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. The Conference Secretary of the First ISAAC Conference is Pam Irwin Department of Mathematics University of Delaware email: irwin@math.udel.edu If you have any questions about the conference, please contact her. The conference has its WWW page at the address http://www.math.udel.edu/isaac/conferen/congr97.htm where also travel and hotel information is available, and at http://www.math.udel.edu/isaac/cong.html there is an online registration form available. The WWW page http://www.zib.de/koepf/isaac.html contains updated informations about the program of Session 13 on "Orthogonal Polynomials". Up to now the program is as follows: Victor Adamchik On Series Involving the Riemann Zeta Function Renato Alvarez-Nodarse Differential and Difference Equations for Orthogonal Polynomials: A Computer Algebra Approach Tewodros Amdeberhan Computer Aided Proofs of a Determinant Identity Ivan Area Inversion Problems for Classical Orthogonal E.

Wolfram Koepf Topic #3 -------------- OP-SF NET 4.1 --------------- January 15, 1997 ~~~~~~~~~~~~~ From: Rudolf Gorenflo Subject: Report on Second International Workshop Transform Methods & Special Functions: Varna, Bulgaria, August 23-30, 1996 The following report appeared in our October 1996 printed Newsletter. This workshop, whose scientific program lasted from August 24 to August 29, 1996, was organized by: 1. Institute of Mathematics and Informatics of the Bulgarian Academy of Sciences; 2. Institute of Applied Mathematics and Computer Sciences of Technical University Sofia; 3. Union of Bulgarian Mathematicians; 4. Union of Scientists in Bulgaria; 5. Istituto per la Ricerca di Base (Monteroduni, Italy). It took place in the hotels Magnolia and Detelina, north of Varna, with a wide view of the Black Sea. It was dedicated to the 100th anniversary of the birth of the Bulgarian mathematician Academician Nikola Obrechkoff (1896-1963, born in Varna) who did pioneering work in such diverse fields as analysis, algebra, number theory, numerical analysis, summation of divergent series, probability and statistics. The workshop was attended by more than seventy participants from twenty countries, alphabetically from Australia to Vietnam, the largest groups coming from Poland (20), Bulgaria (12) and Japan (7). After the opening ceremonies (which included a greeting speech from Varna's Mayor and an appreciation of Obrechkoff and his achievements by I. Dimovski (Sofia) the series of lectures commenced with a plenary lecture by Prof. E.R. Love from Melbourne (Australia), the oldest participant at the Conference, on his joint work with M.N. Hunter on "Expansions in series of Legendre functions". In total there were six plenary lectures, presented by E.R. Love (title already mentioned), F. Mainardi (Bologna, Italy) on "Applications of fractional calculus in mechanics", R. Gorenflo (Berlin, Germany) on "The tomato salad problem in spherical stereology", P.G. Rooney (Toronto, Canada) on "The ranges of Mellin multiplier transformations", H.M. Srivastava (Victoria, Canada) on "Some operational techniques in the theory of special functions", and Vu Kim Tuan (Kuwait) on "Integral transforms and supports of functions". Then 63 lectures were presented in (up to three) parallel sessions with headings "Integral Transforms and Special Functions", "Fractional Calculus", "Special Functions", "Geometric Theory of Functions", "Differential Equations", "Integral Transforms & Operational Calculi", "Mathematical Analysis and Applications", "Integral Transforms", "Varia". In addition, in the closing session P. Rusev, I. Dimovski and V. Kiryakova lectured on "Obrechkoff's generalization of Descartes' rule" and "Obrechkoff's integral transforms". The conference ended with a final ceremony in which P. Antosik (Katowice, Poland) distributed prizes (to the three largest delegations) and praise (to individuals). In the lectures, besides some educational reviews, many new research results were presented. This reporter, due to the multiple sessions, could not attend all the talks; however he feels it appropriate to mention three of them he considered special highlights in that they gave impressive recent results, obtained just in the few weeks preceding the conference. They were two lectures by P.L. Butzer and S. Jansche (Aachen, Germany) on "The Mellin transform, finite Mellin transform and Mellin-Fourier transform", "The Mellin-Poisson summation formula and the exponential sampling theorem", and the plenary lecture by Vu Kim Tuan. In many lectures the importance of special and of general types of special functions for applications inside and outside of mathematics was stressed. Particular mention should be made of hypergeometric functions and their generalizations, H and G functions, confluent hypergeometric functions, Bessel functions, Mittag-Leffler functions, and various types of orthogonal polynomials. The program also provided a two-hour plenary discussion on "Physical and geometrical meanings and applications of fractional calculus operators" that was well attended and opened stimulating aspects. Topics of discussion were, among other things, some problems raised in H.M. Srivastava's collection of "Open questions for further researches on fractional calculus and its applications" (pp. 281-284 in K. Nishimoto, ed., Fractional Calculus and its Applications, Nihon University, Tokyo 1990). In particular, arguments were exchanged on the question whether there is a relationship between fractional calculus and fractal geometry or whether the only relationship is the coincidence of the first five characters of the words "fractional" and "fractal". Fortunately, the discussion did not stick to this problem. The meeting was framed, thanks to the organizers P. Rusev, I. Dimovski, V. Kiryakova, L. Boyadjiev (all from Sofia) and Sh. Kalla (Kuwait), by an appealing social program (reception, on August 27 a whole-day excursion to the old town Shumen, 100 km to the west of Varna, birth-place of Prof. Rusev, and the fascinating surroundings of Shumen, with more than two hours of Bulgarian folklore and after-lunch dancing, and on August 28 a celebration of Prof. Rusev's 65th birthday). Thanks to St. Peter Black Sea sunrises, beach, sand, sun and clear water swimming could be enjoyed. The organizing committee did, in an admirable manner, their best to smooth all the (in retrospect, few) problems that are bound to arise in such a meeting. The Workshop's Proceedings (like those of the preceding one held in Bankya/Bulgaria, 12-17 August 1994) will be published by "Science Culture Technology (SCT) Publishing" in Singapore. Rudolf Gorenflo Topic #4 -------------- OP-SF NET 4.1 -------------- January 15, 1997 ~~~~~~~~~~~~~ From: Renato Alvarez-Nodarse Subject: SCAGOP: Spanish Computer Algebra Group on Orthogonal Polynomials The main aim of our group is the study of Special Functions with particular emphasis on Orthogonal Polynomials by using computer algebra systems.

Berndt has received one of the three 1996 Steele Prizes. Citation: The prize was awarded to Bruce Berndt for his four volumes "Ramanujan's Notebooks", Parts I, II, II, and IV, Springer, 1985, 1989, 1991, and 1994. In recognition of Berndt's heroic and extraordinary achievement in exposing to the general mathematical researcher a trove of results that were utterly inaccessible before, the AMS decided this year, exceptionally, to broaden the standard interpretation of "exposition". In an impressive scholarly accomplishment, spread out over 20 years, Berndt has provided a readable and complete account of the Notebooks, making them accessible to other mathematicians. Ramanujan's enigmatic, unproved formulas are now readily available, together with context and explication, often after the most intense and clever research efforts on Berndt's part. See also Berndt's Response in the Notices, or at http://www.ams.org/publications/notices/199611/comm-steele.html Topic #6 -------------- OP-SF NET 4.1 --------------- January 15, 1997 ~~~~~~~~~~~~~ From: OP-SF Net editor Subject: Joaquin Bustoz receives Presidential Mentoring Award Joaquin Bustoz, Arizona State University, was one of 16 recipients of the first Presidential Awards for Excellence in Science, Mathematics and Engineering Mentoring named by U.S. President Clinton on September 25, 1996. The award recognizes their work in "encouraging minorities, women and persons with disabilities to earn degrees in science, mathematics and engineering" The following information is taken from the December 1996 issue of FOCUS, the Newsletter of the Mathematical Association of America: "Bustoz has received numerous teaching awards, and his research has been in analysis, focusing most recently on orthogonal polynomials and special functions. Since 1985 Bustoz has been involved in enhancing the number and quality of minority students entering the university and intending to study mathematics and science. He initiated and directs a Math-Science Honors Program at ASU, which provides an intense introduction to university mathematics to two hundred high school students each summer. As a direct result of the program, nearly one-third of ASU's mathematics majors are from underrepresented minorities." Topic #7 -------------- OP-SF NET 4.1 --------------- January 15, 1997 ~~~~~~~~~~~~~ From: OP-SF Net editor Subject: CPC Program Library The following information was taken from WWW http://www.cpc.cs.qub.ac.uk/cpc/ Computer Physics Communications (CPC) is an international interdisciplinary journal published by Elsevier Science BV. It is aimed at the computing needs of the computational physics and physical chemistry communities. A unique feature of the CPC journal is its publication of refereed computer programs in physics and physical chemistry. The principal aim of the CPC Program Library is the storage and dissemination of those computer programs whose descriptions have been published in the CPC journal. In January 1996 the CPC Program Library became an integral part of CPC. Under this arrangement a subscription to the CPC journal will include a subscription to the Program Library and each member of a subscribing institute will be permitted to have electronic access to the entire contents of the Program Library. In particular see the library index http://www.cpc.cs.qub.ac.uk/cpc/contents.html The following sections are of interest for OP & SF: 4.1.angular_momentum 4.7 other_functions 5.

There was one further suggestion for revising 1991 Mathematics Subject Classification. Per W. Karlsson wrote: In my opinion, 40A05 is too broad; there should be a separate box for multiple series. This, I think, goes for integrals too (40A10). Several people pointed out that in a list distributed some years ago by Zentralblatt, items 33C25 - 33C55 and 33D25 - 33D45 are at variance with the AMS list. This seems to have been corrected later. Topic #11 -------------- OP-SF NET 4.1 --------------- January 15, 1997 ~~~~~~~~~~~~~ From: Hans Volkmer Subject: Question about Heine polynomials Dear Colleagues, I'm currently working on the polynomials that are treated on pages 151-155 of Szego's book on orthogonal polynomials. I call them Heine polynomials because they were first studied by Heine. They are called Stieltjes polynomials in Morris Marden's book "Geometry of Polynomials". The treatment in Szego's book seems to be rather incomplete. Is there literature on the Heine polynomials in the last decades? Your help would be very appreciated.

Sciences University of Wisconsin-Milwaukee USA email: volkmer@csd.uwm.edu Topic #12 -------------- OP-SF NET 4.1 --------------- January 15, 1997 ~~~~~~~~~~~~~ From: OP-SF Net editor 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.
