PI-OMEGA closed and PI-OMEGAs closed set in supra Topological Spaces

Abstract

The aim of this paper is to define and investigate a weaker class of supra PI-OMEGA closed set in supra topological spaces. New characterizations of supra  closed set are established. We do a comparative study of supra PI-OMEGA  closed and supra PI-OMEGA closed set with the existing sets together with suitable examples. We further discuss the concept of supra  PI-OMEGA and supra PI-OMEGA continuity and obtained their applications.
