COMPLETELY g-CLOSED SETS

Abstract

I. Rajasekaran and O. Nethaji

In this paper, the notion of completely g-?-closed sets is introduced in ideal topological spaces. Characterizations and
properties of completely g-?-closed sets and completely g-?-open sets are given. A characterization of normal spaces is
given in terms of completely g-?-open sets. Also it is established that a completely g-?-closed subset of an I-compact
space is I-compact.
