预叠加的Hochschild上同调比较定理

A Hochschild Cohomology Comparison Theorem for prestacks

Wendy Lowen, Michel Van den Bergh

摘要:

推广和澄清了Gerstenhaber和Schack的“特殊上同调比较定理”。更具体地说,我们得到了一个完全忠实函子之间的导出范畴的双模在一个小范畴U上的预堆栈和导出范畴的双模在其相应的纤维范畴。与Gerstenhaber和Schack相反,我们不必假设U是偏序集。

英文摘要:

We generalize and clarify Gerstenhaber and Schack's "Special Cohomology Comparison Theorem". More specifically we obtain a fully faithful functor between the derived categories of bimodules over a prestack over a small category U and the derived category of bimodules over its corresponding fibered category. In contrast to Gerstenhaber and Schack we do not have to assume that U is a poset.
