On Regular Beta (r?) - Closed Sets in Topological Spaces

Dr. A. Manonmani, S. Jayalakshmi

Abstract: In this paper, we introduce a new class of closed sets called regular closed sets (briefly r closed sets) in topological Spaces. Here we study the relation of these sets with some of the existing closed and generalized closed sets. Also we study some of the characteristics of r closed sets.

Keywords: Topological spaces, r - closed set, - open, regular closure
