Based on the analysis of the muiltiplicative structure of Koszul algebras given by Buchweitz et al,a sufficient and necessary condition for the multiplicative structure of Hochschild cohomology rings of Koszul algebras to be essentially the jux- taposition of parallel paths is obtained.
基于Buchweitz等人对Koszul代数的Hochschild上同调环的乘法结构的细致分析,给出了Koszul代数的Hochschild上同调环的乘法本质上是平行路的毗连的一个充要条件,并由此重新证明了二次三角string代数的Hochschild上同调环的乘法是平凡的,从而改进了Bustamante的证明。
This is the Associative Property of Multiplication. Read after me, please.
