Tom Koornwinder (b. 1943 in Rotterdam, The Netherlands) is Professor Emeritus in the Korteweg–de Vries Institute for Mathematics at the University of Amsterdam, The Netherlands. During 1968–1992 he was a Researcher in the Centrum Wiskunde & Informatica (CWI), Amsterdam.
Koornwinder has published numerous papers on special functions, harmonic analysis, Lie groups, quantum groups, computer algebra, and their interrelations, including an interpretation of Askey–Wilson polynomials on quantum SU(2), and a five-parameter extension (the Macdonald–Koornwinder polynomials) of Macdonald’s polynonomials for root systems BC. Books for which he has been editor or coeditor include Special Functions: Group Theoretical Aspects and Applications (with R. A. Askey and W. Schempp), published by Reidel in 1984, and Wavelets: mathematical preliminaries, published by World Scientific in 1993.
Koornwinder has been active as an officer in the SIAM Activity Group on Special Functions and Orthogonal Polynomials. Currently he is on the editorial board for Constructive Approximation, and is editor for the volume on Multivariable Special Functions in the ongoing Askey–Bateman book project.
