Abstract

The aim of the present paper is to introduce the concept of -- compactness by means of -operation deÖned on the family of -open sets of a topological space. We deÖne the --convergence, --accumulation points of a Ölterbase and give some of their properties. Some characterizations and properties of --compact spaces are obtained.
