|TITLE||Moduli spaces of sheaves and stable pairs|
In this talk, I will briefly review Mumford and Gieseker stability conditions and the corresponding moduli spaces of sheaves. Then, I will proceed to stable pairs. A pair consists of a coherent sheaf and a homomorphism from a fixed coherent sheaf to it. I will also talk about the related deformation-obstruction theory and examples of virtual fundamental classes.
