G*-closed sets in intuitionistic fuzzy topological spaces

Abstract

This paper is devoted to the study of intuitionistic fuzzy topological spaces. In this paper we introduce and study the concepts of intuitionistic fuzzy g*-closed sets and intuitionistic fuzzy g*-open sets in intuitionistic fuzzy topological spaces. We show that intuitionistic fuzzy g*-closed sets lies between intuitionistic fuzzy g-closed sets and intuitionistic fuzzy g-closed sets. We obtained some characterisations and several preservation theorems of the spaces.
