A Pieri formula for Macdonald's spherical functions and polynomials

Representation Theory 2011-09-16 v1 Combinatorics

Abstract

We present explicit Pieri formulas for Macdonald's spherical functions (or generalized Hall-Littlewood polynomials associated with root systems) and their qq-deformation the Macdonald polynomials. For the root systems of type AA, our Pieri formulas recover the well-known Pieri formulas for the Hall-Littlewood and Macdonald symmetric functions due to Morris and Macdonald as special cases.
