摘要 本文利用代数的单点扩张的方法,讨论了截面基本圈代数关于任意一个投射模的单点扩张的Hochschild上同调群,并且说明了其低阶上同调与投射模相关因素有关。 With the method of one point extension of algebra,this paper is to compute the Hochschild cohomology of one point extension of truncated basic cycle about any projective modules,meanwhile illustrating its lower cohomology groups are associated with some factors of the projective modules.
