报告摘要：

If A is a filtered algebra such that the associated graded algebra gr(A) is commutative Calabi-Yau, then A is in general skew Calabi-Yau. In this case, gr(A) has a canonical Poisson structure with a modular derivation. We describe the connection between the Nakayama automorphism of A and the modular derivation of gr(A) by using homological determinants. I will start from the definitions of (skew) Calabi-Yau algebras and homological determinants of (Hopf) actions on them.Some applications will also be given in the talk. This talk is based on a joint work with Ruipeng Zhu.
