本文给出了计算Hochs上同调群的一些结果。我们描述了下上同调群,并提供了几个例子。在遗传代数,根式平方零代数和入射代数的特殊情况下,我们构造方便的投影决议,使我们能够计算它们的上同调群。最后,我们给出了一个计算Hochschild余同调群的归纳方法。
We present some results on computing Hochs­ child cohomology groups. We describe the lower cohomology groups and provide several examples. In the particular case of hereditary algebras, radical square zero algebras and inci­ dence algebras, we construct convenient projective resolutions that allow us to compute their cohomology groups. Finally, we show an inductive method to compute the Hochschild co­ homology groups.
