Martin Kalck (Freiburg), Relative singularity categories: dg-models and applications.

Abstract:
We'll try to explain how relative singularity categories can be used to gain insight into the structure of singularity categories. A key technique is a construction describing the relative singularity category as the perfect derived category of an "explicit" dg algebra.
We will explain this technique and show how it can be applied to unify and extend some results on singularity categories.
This talk is based on joint work with Dong Yang.
