在本文中,我们引入了论域X上的自反关系θ的传递化表示θs的概念,研究了拓扑空间(X,τθ)的基本性质,得到了一些有较大价值的结果,这不仅有助于理解粗糙集理论中的一些基本概念及其性质,而且对拓扑学本身都有理论和实际意义.
In this paper,we introduce the concept ofθs,which is the transmissing expression of a reflexive relationshipθon domain X,study the basic property of topological space (X,τθ) and get some interesting results.This results will be not only conducive to better understanding some basic concepts and their properties on rough set theory,but also have theoretical and actual significance to topology.
