�?*g*- Closed Sets in Topological Spaces

N. Balamani, A. Parvathi

The aim of this paper is to introduce and study a new class of generalized closed sets called ψ*g*-closed sets in topological spaces using ψg - closed sets and ψ-closed sets. We analyse the relations between ψ*g*-closed sets with already existing closed sets. The class of ψ*g*-closed sets is properly placed between the class of ψ- closed sets and the class of g*ψ - closed sets and a chain of relation is proved as follows. r-closed→closed → ψ-closed → ψ*g*-closed→ g *ψ -closed→ ψgˆ -closed→ ψg -closed →gsp-closed
