我们证明一些偏斜群代数具有诺特上同调环,这是从其组成部分继承的属性。该证明是埃文斯群上同调有限生成证明的改编。我们将结果应用到一系列具有正特征的有限维 Hopf 代数的例子中。
We prove that some skew group algebras have Noetherian cohomology rings, a property inherited from their component parts. The proof is an adaptation of Evens’ proof of finite generation of group cohomology. We apply the result to a series of examples of finite-dimensional Hopf algebras in positive characteristic.
