摘要
在Pawlak近似空间意义下研究粗糙集构成的拓扑空间。讨论了当论域不受限于有限集时粗糙集可以构成一个拓扑空间,并从拓扑空间的分离性上证明了其粗糙拓扑空间是一个正规的拓扑空间。
This paper is devoted to the discussion of topological structure of rough sets in Pawlak approximation space.Topological space based on rough sets on the universe which is not restricted to be finite was investigated and it was proved that the rough topological space is a normal space on separability of topological space.
