摘要: The singularity category of a variety, defined as the Verdier quotient of the bounded derived category of coherent sheaves by the subcategory of perfect complexes, encodes the homological information of the singularity. Similarly, with a non-commutative resolution of the singularity, one can associate the relative singularity category. I will talk about the basic properties of singularity categories and relative singularity categories for affine Gorenstein singularities and discuss the relation between them.
