INTERNATIONAL WORKSHOP ON ORTHOGONAL POLYNOMIALS:
"Orthogonal Polynomials and Mathematical Physics"

General Information

Dear Colleagues,

It is well known the increasing attention paid in the last years to the theory of Orthogonal Polynomials. In particular since their applications in a lot of different areas like numerical integration, spectral methods, interpolation, approximation theory, etc. Also in combinatorics, mathematical physics, quantum physics, etc. For this reason the Universidad Carlos III de Madrid organizes every two years an international workshop devoted to this topic. The first edition in 1992 was dedicated to Sobolev orthogonal polynomials, in 1994 to polynomials orthogonal in the unit circle, the IWOP'96 , held in 1996, to the applications of orthogonal polynomials in mathematical physics, IWOP'98 was devoted to the numerical applications and symbolic algorithms, and and the last one, the 2002's edition to the Approximation Theory.
 

The main aim of this 2004's edition of the Workshop was that a reduced number of invited mathematicians discuss and review recent progress of the Theory of Orthogonal Polynomials in Mathematical Physics. The Workshop will take place at the "Sala de Audiovisuales de la Biblioteca" located in the cellar (basement) of the Library (building No. 3 in the map ) of the the Escuela Politécnica Superior of the Universidad Carlos III de Madrid, Leganés (Madrid).

For a detailed map of the the campus of Leganes visit WWW (the Library is the building No. 3 in red). The "Sala de Audiovisuales de la Biblioteca" is in the cell ( click here to see a scheme).

The IWOP04 was sponsored by Comunidad de Madrid, Universidad Carlos III de Madrid, Real Sociedad Matemática Española (RSME) and Sociedad Española de Matemática Aplicada.

The topics considered were: Information Entropy, Imaging Theory, Integrable systems, Special functions, Pade Approximation, Riemann-Hilbert Problem, Orthogonal Polynomials.

There were 14 plenary lectures and 18 short communications. 

How to get Escuela Politécnica Superior

The best way to get the Escuela Politécnica Superior is by using the trains Cercaniaswhich can be reach from Atocha Railway Station Cercanias Line C5 (direction Fuenlabrada) and leave the train in the Station Leganés (not in Zarzaquemada!) which is at 5 min. waking from the University. Also you can use the MetroSur Line 12, and leave at San Nicasio or at Lenanes Central Please see a scheme of getting to the University Campus , or if you prefer, see a more detailed map

    The Proceedings

    The Proceedings of the Workshop will be appear as a special issue of Electronic Transactions on Numerical Analysis (ETNA) (see the URL site http://etna.mcs.kent.edu/). All the participants (invited lectures, short communications and poster) are encouraged to send their contributions to Francisco Marcellán. The dead line is November 30, 2004. The maximun number of pages is 20 for the invited lectures, and 10 pages for the other contributions. The papers should be written in LaTeX, using the SIAM style files and to use available macros for theorems, proofs, abstract, etc. Examples of papers with this style can be found at the ETNA and SIAM home pages (for a little manual see the document Using SIAM's LaTeX Macros). All papers will pass a referee process.
