The Separateness Relative to a Subbase for the Topology
Liu De-jin · College Mathematics · 2011
Covering methods are widely used in rough set theory.The interior and the closure of a subset relative to a subbase for the topology are introduced to study the relationships between the rough sets and the topological space.We introduce and study Separateness relative to a subbase for the topology on the basis of open set and closed set relative to a subbase,and some properties are also discussed.We also obtain the further classification for general topological space defined by separation axiom.
