题 目：Constructing recollements of singularity categories
报告人：周国栋教授 (华东师范大学)
摘要：Given a recollement of derived categories of dg categories, under mild conditions, we can construct a recollement of singularity categories, which restricts to a short exact sequence of bounded singularity categories. We present applications to homological epimorphisms of rings and quasi-coherent sheaves over schemes. This talk is based on a joint work with Haibo Jin and Dong Yang.
