On simple-minded systems over representation-finite self-injective algebras
Jing Guo, Yuming Liu, Yu Ye +1
Let be a representation-finite self-injective algebra over an algebraically closed field . We give a new characterization for an orthogonal system in the stable module categ…
An explicit construction of simple-minded systems over self-injective Nakayama algebras
Jing Guo, Yuming Liu, Yu Ye +1
Recently, we obtained in [7] a new characterization for an orthogonal system to be a simple-minded system in the stable module category of any representation-finite self-injective…
On simple-minded systems and -periodic modules of self-injective algebras
Aaron Chan, Yuming Liu, Zhen Zhang
Let be a finite-dimensional self-injective algebra over an algebraically closed field, 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 of a finite group in terms of the additive decomposition. In particula…
