A Note on Singular Moduli Spaces of Sheaves on K3 Surfaces
arXiv:1011.4745
Abstract
This paper studies deformations and birational maps between singular moduli spaces of semistable sheaves with 2-divisible Mukai vectors on K3 surfaces. It is showed that under certain conditions, two such moduli spaces of the same dimension can be connected by deformations and birational maps.
