某些局部自内射代数的上同调

Cohomology of some local selfinjective algebras

Karin Erdmann

摘要:

证明了某些2-生成自内射代数的上同调是双生成的。这特别适用于代数$A5(β)$为$β\neq 0$在分类的连接霍普夫代数的维度$p^3$超过特征$p$的恩王王。

英文摘要:

We show that the cohomology for some 2-generated selfinjective algebras is finitely generated. This applies in particular to the algebras $A5(β)$ for $β\neq 0$ in the classification of connected Hopf algebras of dimension $p^3$ over characteristic $p$ by Nguyen-Wang-Wang.
