有限生成阿贝尔群的群环的Hochschild上同调的BV-代数结构

A BV-algebra Structure on Hochschild Cohomology of the Group Ring of Finitely Generated Abelian Groups

Andrés Angel, Diego Duarte

摘要:

本文研究了一个关于群环的Hochschild上同调的Batalin-Vilkovisky代数结构。有限阿贝尔群的Batalin-Vilkovisky代数结构来自于有限群的群环是对称代数,有限秩的自由阿尔贝群的Batalin-Vilkovisky代数结构来自于它的群环是Calabi-Yau代数。

英文摘要:

We study a Batalin-Vilkovisky algebra structure on the Hochschild cohomology of the group ring of finitely generated abelian groups. The Batalin-Vilkovisky algebra structure for finite abelian groups comes from the fact that the group ring of finite groups is a symmetric algebra, and the Batalin-Vilkovisky algebra structure for free abelian groups of finite rank comes from the fact that its group ring is a Calabi-Yau algebra.
