摘要
本文对每个环定义了同调维数lSWD(R),并讨论了该维数与环的弱维数之间的关系,同时给出了SF一环的两个主要结果。文献[4]中的定理2、命题3是本文的主要结果的推论。
We define a dimension(1SWD(R)),and study the relation on this dimensionwith weak dimension,and give two main results on SF-ring. Theorem 2 and proposi-tion 3 in[4] are the corollary of main results in this paper.
