On simple-minded systems and $τ$ -periodic modules of self-injective algebras

Aaron Chan, Yuming Liu, Zhen Zhang

Let $A$ be a finite-dimensional self-injective algebra over an algebraically closed field, $C$ a stably quasi-serial component (i.e. its stable part is a tube) of rank $n…

The Batalin-Vilkovisky structure on the Tate-Hochschild cohomology ring of a group algebra

Yuming Liu, Zhengfang Wang, Guodong Zhou

We determine the Batalin-Vilkovisky structure on the Tate-Hochschild cohomology of the group algebra $k G$ of a finite group $G$ in terms of the additive decomposition. In particula…
