摘要: 讨论了当论域不限制是有限集时满足自反、传递关系的广义近似空间中的近似算子的拓扑结构;证明了论域 上满足自反、传递关系的集合与其上所有的拓扑的集合是一一对应的;指出了该拓扑空间的拓扑基。

Abstract: We investigated the topological structure of approximation operators satisfied reflexive and transitive rela- dons on the universe which is not restricted to be finit. It was proved that there is a oncto-one correspondence between the set of all reflexive and transitive relations and the set of all topologies. It gave the base of topological space.
Key words: Rough set, Topology, Approximation operator, Reflexive relation, I}ransitivc relation
