Taft代数的Auslander代数的Hochschild上同调群

Hochschild cohomology of Auslander algebras associated to Taft algebras

设Λn是代数闭域k上的有限维Taft代数,Γ是Λn所对应的Auslander代数,用组合的方法清晰地计算了Γ的各阶Hochschild上同调群的维数.

Let An be a Taft algebra over an algebraically closed field k, and Г the Auslander algebra associated to An. Calculated explicitly the dimentions of the Hochschild cohomology groups of Г using the combinatorial method.
