Topic #1 ----------- OP-SF NET 10.1 ------------ January 15, 2003 ~~~~~~~~~~~~~~ From: Walter Van Assche Subject: Conference on "Spectral theory and inverse spectral theory for Jacobi operators" There will be an AMS-IMS-SIAM Summer Research Conference on "Spectral theory and inverse spectral theory for Jacobi operators" in Snowbird, Utah, from June 8 to June 12, 2003. The organizers are Svetlana Jitomirskaya, University of California, Irvine (szhitomi@math.uci.edu) Kenneth T-R McLaughlin, University of North Carolina, Chapel Hill (mcl@amath.unc.edu) Xin Zhou, Duke University (zhou@math.duke.edu) The following are confirmed participants: Jinho Baik (Princeton University) Percy Deift (Courant Institute) Nicholas Ercolani (University of Arizona) Mourad Ismail (University of Southern Florida) Svetlana Jitomirskaya (University of California, Irvine) Rowan Killip (University of Pennsylvania) Alexander Kiselev (University of Chicago) Abel Klein (University of California, Irvine) Thomas Kriecherbauer (University of Bochum, Germany) Arno Kuijlaars (Catholic University of Leuven, Belgium) Doron Lubinsky (Georgia Tech.)

The hope is to provide opportunities for cross fertilization of ideas between these two areas. Information can be found on http://www.amath.unc.edu/SRC602.html Topic #2 ----------- OP-SF NET 10.1 ------------ January 15, 2003 ~~~~~~~~~~~~~~ From: Walter Van Assche Subject: Summer School in Portugal There will be a summer school on "Orthogonal Polynomials and Special Functions" in Portugal from July 14 to July 26, 2003 at the Universidade de Coimbra. The theme of this summer school is "Approximation and Iteration". This is the next summer school in a series; The first was the school in Laredo, Spain, in 2000, the second in Inzell, Germany, 2001, and the third in Leuven, Belgium, in 2002. The goal of the Summer School is to give four introductory courses in advanced research topics on orthogonal polynomials, approximation and iteration theory. Some free discussions and some informal seminars will also be available. The expected audience are graduate and recent postgraduate students as well as young active researchers. The topics to be considered will be: Orthogonal Polynomials Approximation Theory Iteration theory Matrix moment problems Birth and death processes Integral Transforms Number Theory The local organizing committee for this summer school consists of Am?lcar Branquinho, Departamento de Matem?tica da Universidade de Coimbra, Coimbra, Portugal (ajplb@mat.uc.pt) Ana Foulqui?, Departamento de Matem?tica da Universidade de Aveiro, Aveiro, Portugal (foulquie@mat.ua.pt) The lecturers and their topics are as follows: C. Berg (Kobenhavns Universitet, Kobenhavn, Denmark): Matrix moment problems. J. Bustoz (Arizona State University, USA): Classical summability theory and q-series. G. L?pez Lagomasino (Universidad Carlos III de Madrid, Madrid, Spain): Constructive theory of approximation. F.

In his honor there will be a conference in Roros, Norway in the week of August 11 - 16. 2003. Roros is an old historic town not far from Trondheim. It is on UNESCO's World Heritage list. Please respond to lisa@math.ntnu.no by January 31, 2003 if you want to receive further information. Kind regards, Lisa Lorentzen, Frode Ronning and Haakon Waadeland Topic #4 ----------- OP-SF NET 10.1 ------------ January 15, 2003 ~~~~~~~~~~~~~~ From: Paolo Emilio Ricci <"Paoloemilio Ricci"@uniroma1.it> Subject: Copenhagen Open Problem Session As you probably know, the Scientific Committee of the 7th International Symposium on Orthogonal Polynomials, Special Functions and Applications, (OPSFA) to be held in Copenhagen, during August 2003 (see OP-SF NET 8.6, Topic #7, OP-SF NET 9.4, Topic #6) has charged me with organizing the "Open Problem Session" of the meeting. To this end, I hope you are interested in participating in this session. If you have a good problem to present, you could prepare a (maximum) 10--15 minutes talk containing a presentation of the scientific background of the problem and your conjectures about a possible solution. If you agree with this proposal, please send me at your earliest convenience (but not later than June 30, 2003), a short confirmation e-mail message, in order I can have an idea about the number of contributors.
