On the moduli of stable sheaves on a reducible projective scheme and examples on a reducible quadric surface
Published online by Cambridge University Press: 22 January 2016
Abstract
We study the moduli space of stable sheaves on a reducible projective scheme by use of a suitable stratification of the moduli space. Each stratum is the moduli space of “triples”, which is the main object investigated in this paper. As an application, we can see that the relative moduli space of rank two stable sheaves on quadric surfaces gives a nontrivial example of the relative moduli space which is not flat over the base space.
