摘要
． 我们将给出广义四元数Z代数G的1‰的双模投影解析。作为主要结果，我们将通过使用该分辨率计算Yoneda积来确定Hochschild上同调HH (cid:1) ð G Þ的环结构。
Hochschild cohomology ring of the generalized quaternion algebras
. We will give an e‰cient bimodule projective resolution of the generalized quaternion Z algebra G . As a main result, we will determine the ring structure of the Hochschild cohomology HH (cid:1) ð G Þ by calculating the Yoneda products using this resolution.
