报告题目：Artin-Schelter regular algebras and related topics
报告摘要：In this talk, we will talk about some homological properties of AS-regular algebras, including Batalin-Vilkovisky structure on Hochschild cohomology and Gravity structure on negativ cyclic homology. In some cases, we prove that these structures are invariant under Koszul duality and deformation quantization. If time permit, we will talk about singularity categories of some Gorenstein rings
