The Connectedness Relative to a Subbase for the Topology
Jinjin Li · Advances in Mathematics · 2007
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 connectedness relative to a subbase for the topology,and obtain their some properties,which generalize connectedness in a general topology.
