Singularities and Kodaira dimension of moduli scheme of stable sheaves on Enriques surfaces

Abstract

Let M be a moduli scheme of stable sheaves with fixed Chern classes on an Enriques surface or a hyper-elliptic surface. If its expected dimension is 7 or more, then M admits only canonical singularities. Moreover, if M is compact, then its Kodaira dimension is zero.
