Topic #1 ------------ OP-SF NET 7.5 ------------- September 15, 2000 ~~~~~~~~~~~~~ From: Daniel Lozier Subject: Letter from the Chair In this letter to the OPSF membership I want to report on some recent developments at SIAM that affect all the SIAGs (SIAM Activity Groups) and ours in particular. Then I will give a brief report on the SIAM Annual Meeting, which was held in San Juan, Puerto Rico. Finally I will raise some issues faced by our Activity Group and ask for ideas for addressing them. To begin, this was the year for our charter to be considered for renewal by the SIAM Council and the SIAM Board of Trustees. Activity group charter renewal is required every three years. I submitted the application, which was considered and approved at the Annual Meeting. Thus we are in business until the end of 2004. Officers who will lead our group starting on January 1, 2002, will be elected by the membership next year. It is not too soon to begin thinking about candidates, and to think about being a candidate yourself. Jim Crowley, Executive Director of SIAM, sent an email to all SIAG officers reporting two actions taken by SIAM at the Annual Meeting that affect the SIAGS. The first action is a request that all SIAGs organize at least two minisymposia at each Annual Meeting. This reaffirms previous requests and reflects the importance SIAM places on the activities of the SIAGs. There is a desire, in Jim's words, "to see the SIAGs participate fully as part of SIAM and not become entirely separate entities." The second action is new. It requests a meeting of the chairs of all the SIAGs at each Annual Meeting to discuss issues facing the SIAGs and to seek ways of vitalizing each SIAG. Jim will conduct the first SIAG Chairs Meeting at the 2001 SIAM Annual Meeting in San Diego. I expect to attend and represent our membership at this meeting. Jim's email covered other issues of interest to SIAG officers and potential officers. New or revised documents for SIAG officers are being prepared, including SIAG Rules of Procedure, SIAG Guidelines, Guidelines for Organizing a SIAG Conference, and the charter renewal template. Finally Jim's email commented that every SIAG should maintain a set of Web pages. Any member who is interested in more information about these topics should contact me. Our group had a minisymposium at the San Juan meeting but, unfortunately, it was not well attended. Of course there were many competing parallel sessions. But one of our four talks was cancelled due to a last-minute problem that prevented the speaker from traveling to San Juan, and another attracted no audience at all! One reason for the poor attendance might be that our talks didn't adhere to a coherent theme. It didn't help that among the plenary talks only one, the Polya Prize Lecture on Polynomials in Discrete Mathematics, had anything to do with our subject. Finally, the 3rd European Congress of Mathematics took place in Barcelona the same week as the SIAM Annual Meeting. Though it was a general mathematics meeting, a satellite Summer School on Orthogonal Polynomials and Special Functions was held shortly afterward. This summer school was an official activity of our group, organized by our program director, Paco Marcellan, and one of our newsletter editors, Renato Alvarez-Nodarse. I believe the European meeting and summer school drew heavily from the attendance we would have expected in San Juan. This leads me to the major issue I see facing our group. We are part of SIAM, and SIAM rightly expects us to participate in SIAM meetings, to organize parts of these meetings, and even to consider mounting our own SIAG conference. In my view our group has met these expectations quite well, except for conducting our own conference, which we have never done. There are two general problems that prevent us from having a stronger relationship with SIAM. First, SIAM's commitment to special functions is not as strong as it should be. One indication of this is the lack of plenary speakers who work in special functions or who use them in other areas. I discussed this problem with several people in San Juan, and came away with the feeling that we could do more to influence the program of future SIAM meetings by communicating directly with the program committees. Another problem is the drift away from classical analysis on the editorial board of the SIAM Journal on Mathematical Analysis. This was addressed in the "Statement by the Officers of SIAM SIAG-OPSF on the Scope of SIMA" in Topic #7, OPSF-NET 7.3, May 15, 2000, and in the printed OPSF Newsletter, vol. 10, no. 3, June 2000, p. 22. I am not aware of any progress on this problem. Second, there are many meetings that focus sharply on special functions. Are there too many? I invite the membership to think about our relationship with SIAM and how it could be strengthened. Our email list service, OPSF-Talk, is ideal for this purpose. It distributes email sent to opsftalk@nist.gov to the subscriber list, and it keeps an archive of the email. See http://math.nist.gov/opsf/opsftalk.html for further information about this service. Of course I will also be happy to receive comments by email, telephone or letter. Topic #2 ------------ OP-SF NET 7.5 ------------- September 15, 2000 ~~~~~~~~~~~~~ From: OP-SF NET Editor Subject: Program on Symmetric functions and Macdonald polynomials [From the website: http://www.newton.cam.ac.uk/programs/sfm.html] The Isaac Newton Institute for Mathematical Sciences, Cambridge, UK will host a program "Symmetric functions and Macdonald polynomials" during January-June 2001. The organisers are P. Hanlon (Michigan), I.G. Macdonald (London) and A.O. Morris (Aberystwyth). Programme Theme: The importance of symmetric functions and the representation theory of Hecke algebras and the symmetric groups derives in part from their applicability in a wide range of scientific and mathematical disciplines. Within the theory of symmetric functions, this programme will focus on a particular topic, the Macdonald polynomials, which have especially wide-ranging mathematical interconnections. The goal of the program will be to unify the diverse approaches to the study of these polynomials. In the 1980's, I. G. Macdonald formulated a series of conjectures which predicted the constant terms of expressions that involve an important new class of symmetric functions called the Macdonald polynomials. Since their introduction, these conjectures and polynomials have been a central topic of study in Algebraic Combinatorics. Of particular note has been the variety of approaches used in efforts to solve the conjectures or to find an algebraic or geometric interpretation for the Macdonald polynomials themselves. Different approaches involve double affine Hecke algebras, homology of nilpotent Lie algebras, generalized traces of Lie algebra representations and diagonal actions of the symmetric group on polynomial rings in two sets of variables. In this programme we will attempt to unify these different approaches to the Macdonald Conjectures in a way that allows for a significant interpretation of the Macdonald polynomials and settles some of the outstanding conjectures that have resulted from this work. Links with other areas such as algebraic geometry, Lie algebras, non-commutative algebra, mathematical physics and mathematical statistics will be emphasised. Workshops will be arranged in order to foster existing and potential applications in these and other subjects. Workshops: - 8-12 January 2001: Conjectures, Recent Results and Open Problems Related to the Macdonald Polynomials - 17-20 April 2001: Applications of the Macdonald Polynomials - 25 June - 6 July 2001: The Macdonald Polynomials A list if visitors and visiting dates is maintained at the web site: http://www.newton.cam.ac.uk/programs/sfm.html Contacts: A. O. Morris P. Hanlon Topic #3 ------------ OP-SF NET 7.5 ------------- September 15, 2000 ~~~~~~~~~~~~~ From: Mourad Ismail Subject: Hong Kong Summer School in Applied Analysis Summer School in Applied Analysis Dates: July 2nd- July 13, 2001 Place: City University of Hong Kong Organizing Committee: Joaquin Bustoz, Mourad Ismail, Rupert Lasser, Jurgen Prestin, Rod Wong. Conference Secretary: Colette Lam. Contact Information: malam@cityu.edu.hk Lecturers (Confirmed): A. Grunbaum (Berkeley) M. E. H. Ismail (U South Florida and City U), A. Its (IUPUI and U Penn), R. Lasser (Munich), B. Simon (Caltech), W. Van Assche (Leuven), and Rod Wong (City U). In addition to the above structered courses we intend to have several one hour talks on more advanced topics. This will be done in the later part of the program. Topic #4 ------------ OP-SF NET 7.5 ------------- September 15, 2000 ~~~~~~~~~~~~~ From: OP-SF NET Editor Subject: New book on Special Functions The following information is from the web site: http://www.oup-usa.org/isbn/0198505736.html Special Functions - A Unified Theory Based on Singularities Wolfgang Lay (Stuttgart) and Sergei Yuryevitsh Slavyanov (St. Petersburg) Oxford University Press, 320 pp.; 50 line illus; 0-19-850573-6, November 2000 The subject of this book is the theory of special functions, not considered as a list of functions exhibiting a certain range of properties, but based on the unified study of singularities of second-order ordinary differential equations in the complex domain. The number and characteristics of the singularities serve as a basis for classification of each individual special function. Links between linear special functions (as solutions of linear second-order equations), and non-linear special functions (as solutions of Painleve equations) are presented as a basic and new result. Many applications to different areas of physics are shown and discussed. The book is written from a practical point of view and will address all those scientists whose work involves applications of mathematical methods. Lecturers, graduate students and researchers will find this a useful text and reference work. CONTENTS Preface 1. Linear Second-order ODE with Polynomial Coefficients 2.

SFTools - Database of the Special Functions Topic #5 ------------ OP-SF NET 7.5 ------------- September 15, 2000 ~~~~~~~~~~~~~ From: Daniel Lozier Subject: Postdoctoral Research Opportunity at NIST This research opportunity focuses on improving numerical and symbolic computing support for the classical special functions in parallel and other advanced computational settings through the development of algorithms and mathematical software. Emphasis in algorithm development is placed on functions of one or more complex variables. For example, a recurrence relation or differential equation can sometimes be solved in parallel to form a stable and effective algorithm in the complex domain. This approach has been applied successfully to Airy, Bessel, and other functions. The emphasis in software development is placed on the construction of robust and highly reliable packages and test procedures. An important component is the use of the Internet to provide an interactive capability in the dissemination of mathematical reference data for special functions. The further development of these topics will require skills in real and complex analysis, numerical analysis, classical special functions, approximation theory, and advanced computing. For further information, contact: Dr. Daniel W. Lozier National Institute of Standards and Technology 100 Bureau Drive Gaithersburg, MD 20899-8910 E-mail: dlozier@nist.gov, telephone: (301) 975-2706 The postdoctoral research program at NIST is administered by the National Research Council, Washington, DC. Only US citizens are eligible. The duration is two years. The application deadline is January 15, 2001.

Topic #6 ------------ OP-SF NET 7.5 ------------- September 15, 2000 ~~~~~~~~~~~~~ From: Erik Koelink Subject: Job opening for graduate student 4-year graduate student position "Special Functions and Dynamical Quantum Groups" This concerns a NWO (Netherlands Organization for Scientific Research)-funded project to be carried out at the Technische Universiteit Delft, the Netherlands. The research group consists of Erik Koelink (Delft, the Netherlands), Hjalmar Rosengren (Gothenburg, Sweden), Ole Warnaar (Melbourne, Australia), and as external advisors Tom Koornwinder (Amsterdam, the Netherlands) and Don Zagier (Utrecht, the Netherlands). A short description of the research proposal is the following: The purpose of this proposal is to investigate the relationship between the representation theory of dynamical quantum groups and the theory of special functions. Dynamical quantum groups are related to solutions of the dynamical Yang-Baxter equation and we focus our attention to the so-called trigonometric and elliptic solutions. We will study representations and co-representations and we intend to establish a fruitful link with classes of special functions, leading to new insights on both sides. In the trigonometric case we expect special functions of basic hypergeometric type, and in the elliptic case we expect special functions of elliptic hypergeometric type. Candidates should have a degree in mathematics or physics, or obtain one in the near future.
