K-Theoretic Descendent Series for Hilbert Schemes of Points on Surfaces

Algebraic Geometry 2022-10-18 v3 Combinatorics

Abstract

We study the holomorphic Euler characteristics of tautological sheaves on Hilbert schemes of points on surfaces. In particular, we establish the rationality of K-theoretic descendent series. Our approach is to control equivariant holomorphic Euler characteristics over the Hilbert scheme of points on the affine plane. To do so, we slightly modify a Macdonald polynomial identity of Mellit.
