ABSTRACT

I will give an elementary introduction to the theory of Macdonald
polynomials (for a root system of type A), and then explain my work
with A.Kirillov Jr. (1994) where this theory is connected with
representation theory of the quantum
group U_q(gl(n)). This allows to obtain a representation theoretic
interpretation of all the main identities with Macdonald polynomials
(constant term, inner product, evaluation, symmetry,
MacdonaldMehtaCherednik), and to generalize Macdonald polynomials to
the affine root system \hat A_n.
