Hilbert Schemes of Points on Canonical Surfaces
Ryo Yamagishi (University of Bath)
Abstract
The celebrated result of Fogarty claims that the Hilbert scheme of n points on a smooth surface is a smooth variety of dimension 2n. In this talk, as an analogue of this result, I will show that the Hilbert scheme of n points on a normal surface with canonical singularities is a normal variety of dimension 2n. The proof is done by realizing the Hilbert scheme for a specific surface singularity as a Nakajima quiver variety. This talk is based on joint work with Alastair Craw.
