First account of a theory, created by Macdonald, of a class of orthogonal polynomial, which is related to mathematical physics.

This is an essentially self-contained monograph centered on the new double Hecke algebra technique.

There has been revived interest in recent years in the study of special functions. Many of the latest advances in the field were inspired by the works of R. A.

This new book presents research in orthogonal polynomials and special functions. Recent developments in the theory and accomplishments of the last decade are po

Two basic problems of representation theory are to classify irreducible representations and decompose representations occuring naturally in some other context.
