(q,t)-hook formula for Birds and Banners

Combinatorics 2013-02-11 v1

Abstract

We study Okada's conjecture on (q,t)(q,t)-hook formula of general dd-complete posets. Proctor classified dd-complete posets into 15 irreducible ones. We try to give a case-by-case proof of Okada's (q,t)(q,t)-hook formula conjecture using the symmetric functions. Here we give a proof of the conjecture for birds and banners, in which we use Gasper's identity for VWP-series 12W11{}_{12}W_{11}.
