Abstract

For any partition λ let ω(λ) denote the four parameter weight (equation presented) and let ℓ(λ) be the length of λ. We show that the generating function Σω(λ)z ( λ), where the sum runs over all ordinary (resp. strict) partitions with parts each ≤ N, can be expressed by the Al-Salam-Chihara polynomials. As a corollary we prove G.E. Andrews' result by specializing some parameters and C. Boulet's results when N → +∞. In the last section we study the weighted sum Σω(λ)z ℓ(λ)P λ(x) where P λ(x) is Schur's P-function and the sum runs over all strict partitions.
