Title: Combinatorics of the q,tsymmetry relation in Macdonald polynomials
Abstract: The Macdonald polynomials H_mu(X;q,t) are certain symmetric functions in the variables X={x_1,x_2,...} with coefficients in Q(q,t). Arising naturally in the context of the geometry of the Hilbert scheme of points in the plane, these polynomials also exhibit a beautiful symmetry relation in the variables q and t. We investigate the combinatorics of this symmetry relation in light of the combinatorial formula for the Macdonald polynomials discovered by Haglund, Haiman, and Loehr in 2004. The relation is a strict generalization of the wellknown equidistribution of the Mahonian statistics inv and maj on permutations.
