Intuitionistic Smooth Fuzzy $\theta$-Closure Operator

Abstract

In this paper, the concepts of intuitionistic $r$-fuzzy $\theta$-open ($\theta$-closed) sets and intuitionistic $r$-fuzzy $\theta$-closure operator are introduced and discussed in intuitionistic smooth fuzzy topological spaces. As applications of these concepts, certain functions are characterized in terms of intuitionistic smooth fuzzy $\theta$-closure operator.
