Abstract

Though there are many studies on the topological properties of rough set approximations, only a few works have been done on the concept of rough topology. In this paper, a new definition of rough topology on an approximation space is proposed using the rough subsets of the extended approximation space. The basic concepts of a topological space are extended to the proposed rough topological space and the properties are investigated.
