arXiv:1009.4482 · doi:10.1007/s00209-010-0727-0
Abstract
We present explicit Pieri formulas for Macdonald's spherical functions (or generalized Hall-Littlewood polynomials associated with root systems) and their -deformation the Macdonald polynomials. For the root systems of type , 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.
