Affine Hecke algebras and raising operators for Macdonald polynomials

q-alg 2008-02-03 v1 Quantum Algebra

Abstract

We introduce certain raising and lowering operators for Macdonald polynomials (of type An1A_{n-1}) by means of Dunkl operators. The raising operators we discuss are a natural qq-analogue of raising operators for Jack polynomials introduced by L.Lapointe and L.Vinet. As an application we prove the integrality of double Kostka coefficients. Double analog of the multinomial coefficients are introduced.
