论文摘要
对于由双川扭曲的代数的张量产品，我们完全将其Hochschild共同体描述为Gerstenhaber代数，以其组成部分的Hochschild共同论。此描述概括了Bergh和Oppermann的结果。它使我们能够显着简化文献中的各种计算，并为许多新示例计算Hochschild协同学。
For a tensor product of algebras twisted by a bicharacter, we completely describe its Hochschild cohomology, as a Gerstenhaber algebra, in terms of the Hochschild cohomology of its component parts. This description generalizes a result of Bergh and Oppermann. It allows us to significantly simplify various calculations in the literature, and to compute Hochschild cohomology for a number of new examples.
