Affine Hecke Algebras and Orthogonal Polynomials - Macdonald, I. G. (Queen Mary University of London)

There has recently developed a satisfactory and coherent theory, created by the author, of orthogonal polynomials in several variables, attached to root systems, and depending on two or more parameters. This Tract, the first comprehensive and organised account of the subject, provides a unified foundation for this theory.
