摘要
通过讨论粗糙集理论在代数系统——群上的应用,引入了群中的上、下近似和商群中的上、下近似等概念,提出并证明了与此相关的性质.
This paper discusses the application of rough set theory on algebra system-group,introduces such concepts as the lower and upper approximation on group and on group of quotient,points out and gives proof of several related properties.
