设A是k-代数,H是Hopf代数,E = A#H是一般交叉积,M是E-双模.我们得到了一个比标准复形更简单的复形,给出了E的Hochschild同调,其系数在M中。这种复合物与自然过滤相当。我们证明了相关的谱序列与Hochschild-Serre直接方法或Cartan-Leray-Grothendieck方法得到的谱序列一致。对于上同调,我们也得到了类似的结果。
Let A a k-algebra, H a Hopf algebra, E = A#H a general crossed product and M an E-bimodule. We obtain a complex simpler than the canonical one, giving the Hochschild homology of E with coefficients in M. This complex is eqquiped with a natural filtration. We prove that the associated spectral sequence coincides with that obtained by either, the Hochschild-Serre direct method or the Cartan-Leray-Grothendieck method. We also get similar results for the cohomology.
