报告摘要
The classical result of Rickard asserts that the center of a finite dimensional algebra is invariant under derived equivalences. In this talk I will discuss a generalization of this result to algebras graded by finite abelian groups (in particular, to superalgebras, that is algebras graded by a cyclic group of order two). This is based on a joint work with Kevin Coulembier.
