JUNE 18 - 22, 2001



    Dear colleague,
the Department of Mathematics of the University Roma Tre and the Department of Mathematics "Guido Castelnuovo" of the University of Roma "La Sapienza" are delighted to organize the Sixth international Symposium on Orthogonal Polynomials, Special Functions and their applications (OPSFA), which will be held for the first time in Roma on June 18 - 22, 2001. Since we received many preregistration forms, we expect about 200 scientists from all over the world. The Symposium is partially granted by C.N.R. - G.N.I.M. (National Research Council - National Group for Mathematical Informatics).
    As we wrote in the old web page, the Symposium will take place in a great hotel situated at Lido di Ostia, that is the seaside resort at the outskirts of Roma; all participants will be lodged in the same hotel, and will be freely transported from and to the International Airport "Leonardo da Vinci" of Fiumicino (which is a few km away) by the hotel's bus. Also, it is easy to reach the centre of Roma from the Symposium site, since a new train station (Lido di Ostia Nord) was opened near the hotel just a few months ago. Anyway, participants which do not want to go to Roma may also find a very pleasant environment in Ostia.
    We look forward to seeing you in Roma next June.



    The 6th International Symposium OPSFA follows the European Conferences of Bar-Le-Duc (France, 1984), Segovia (Spain, 1986), Erice (Italy, 1990), Granada (Spain, 1991, VII SPOA), Evian (France, 1992), Delft (Holland, 1994, in honour of Thomas Jan Stiltjes Jr. (1856-1894)), Sevilla (Spain, 1997, VIII SPOA) and Patra (Greece, 1999, in honour of Theodore Chihara). It covers the field of orthogonal polynomials and special functions and their applications in the other areas of mathematics, physics and other sciences. This Symposium is a forum for presentation and discussion of all aspects of orthogonal polynomials and special functions, ranging from the fundamental to the applied.
    The aim of the Symposium is to provide a common meeting ground for specialists in orthogonal polynomials, special functions and related topics, such as moment problems, rational approximation, matrix orthogonal polynomials, Sobolev orthogonal polynomials as well as in the rich variety of scientific applications of these objects.
    The scientific program includes plenary lectures and research seminars. An approximate timetable will be given in the third circular, which will be sent to all those who register for the Symposium. The final program will be given on the registration desk on June 17 (Sunday).



    There will be 8 plenary lectures and around 100 research seminars or contributed talks organized into parallel sessions. The time assigned for a plenary lecture is 60 minutes (50' for presentation and 10' for discussion); research seminars are assigned 25 minutes (20' for presentation and 5' for discussion). All participants are invited to submit a 25-minutes research seminar; please send us a short abstract (not more than 15 - 20 lines) of your talk in TEX or LATEX format not later than March 31, 2001. In order to simplify our work, please send your file with filename surname.tex, using your surname, shortened if necessary (not more than 8 characters).

    The invited speakers are:
  • R. Askey (University of Wisconsin - USA)
  • C. Dunkl (University of Virginia - USA)
  • └. Elbert (Academy of Sciences Budapest - Hungary)
  • D. Sattinger (Utah State University - USA)
  • D. Stanton (University of Minnesota - USA)
  • S. K. Suslov (Arizona State University - USA)
  • N. Temme (C.W.I. - Netherlands)
  • W. Van Assche (K.U. Leuven - Belgium)

    Invited speakers are also requested to send a one page abstract of their plenary lecture in TEX or LATEX format not later than March 31, 2001.


    The book of abstracts will be distributed to the participants upon the registration at the Symposium desk. The proceedings of the Symposium will be published on an important international mathematics journal (more details will be given in the third circular).



    Althought the deadline for registration has expired, we are still accepting new registrations without any additional fee, UNTIL MARCH 31. Please complete the enclosed registration form and return it as soon as possible via Internet.

  • admission to the Symposium;
  • Symposium documents;
  • book of abstracts;
  • Symposium Proceedings;
  • official reception / welcome drink;
  • lunch in the hotel from Tuesday to Friday;
  • guided visit to Roma's surroundings;
  • other social events being studied.

Accompanying person's fee includes:

  • transportation from the airport "Leonardo da Vinci" to the hotel and vice versa;
  • official reception / welcome drink;
  • guided visit to Roma's surroundings;
  • other social events being studied.

Cancellation must be made in writing to the Organizing Committee.
The following rules will apply:

  • cancellation received before April 15, 2001: 80% refund;
  • cancellation received before May 25, 2001: 50% refund;

    In special cases, the Organizing Committee will send a personal invitation for participation to the Symposium. It should be understood that such an invitation is not a commitment on the part of the organizers to provide any financial support



    The Symposium will take place at the Hotel SATELLITE PALACE, located at Lido di Ostia (Roma). Some beaches (both bathing establishments and free beaches) are easily accessible from the hotel. Participants who reach Roma by air will have a free transportation from the International Airport "Leonardo da Vinci" to the hotel by a bus of the hotel "Satellite Palace".
    The centre of Roma may be easily reached from the Symposium site, since a new station (Lido di Ostia Nord) of the railway Roma Porta S. Paolo - Lido di Ostia, located near the hotel (less than 5' on foot), was opened a few months ago. During the night a bus substitutes the train, so it is possible to return to the hotel at any time.
    On your arrival to the hotel you may buy at the information desk a weekly card (at the cost of lire 24000 = Euro 12.40) which allows you to travel on every bus, tram, metro, train in Roma and Lido di Ostia (it is very useful if you are thinking to go often to the centre of Roma or to the beach). The weekly card is not valid on the blue buses of company "COTRAL" connecting Lido di Ostia to the Airport of Fiumicino.
    You may also buy some tickets "B.I.T." which allows you to travel on bus, tram, train and metro for 75'. The cost of each ticket is 1500 lire (Euro 0.77).



    There will be an official reception with welcome drink and lunch on Monday 18, a guided visit to Roma's surroundings and the Conference Banquet on Wednesday 20. Also, we are preparing a musical entertainment.



    Registration must be received before April 1, 2001. After sending the form, please pay your registration fee as soon as possible. Abstracts of plenary lectures and of research seminars must be received before March 31, 2001.
