Intuitionistic Fuzzy Ideals Supra Topological Spaces

Abstract

Fadhil Abbas

In this paper we introduce the notion of intuitionistic fuzzy ideals in intuitionistic fuzzy supra topological spaces. The concept of an intuitionistic fuzzy s-local function is

also introduced here by utilizing the s-neighbourhood structure for an intuitionistic fuzzy supra topological space. These concepts are discussed with a view to find new

intuitionistic fuzzy supra topologies from the original one. The basic structure, especially a basis for such generated intuitionistic fuzzy supra topologies and several

relations between different intuitionistic fuzzy ideals and intuitionistic fuzzy supra topologies are also studied here. Moreover, we introduce an intuitionistic fuzzy set

and study its properties. Finally, we introduce some sets of fuzzy ideal supra topological spaces (fuzzy
