摘要
本文给出了一个用于计算域上余连通dga的Hochschild上同调的谱序列。该谱序列与Cohen、Jones和Yan为计算闭可定向流形的环同伦所构造的谱序列具有相似的风味。利用该谱序列,我们识别了一类空间,其mod-p上链代数的Hochschild上同调是Noetherian的。这尤其意味着,对于此类空间,其环空间上的mod-p链的导出范畴承载了支撑簇理论。

Final version. The new version adds an application of the results to the construction of support varieties for modules over the chains algebra of certain loop-spaces. See Corollary 1.7 and Proposition 2.4
