Report title: Filtered Quantization, Skew Calabi-Yau algebras and Poisson algebras


Reporter: Professor Wu Quanshui Fudan University


Reporting time: November 26, 2020 9:00-10:00


Report location: Tencent Meeting: 331653045


School contact: Sheng Yunhe shengyh@jlu.edu.cn




Report summary:


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.
