Delta Closure and Delta Interior in Intuitionistic Fuzzy Topological Spaces

Abstract

Due to importance of the concepts of θ-closure and δ-closure, it is natural to try for their extensions to fuzzy topological spaces. So, Ganguly and Saha introduced and investigated the concept of fuzzy δ-closure by using the concept of quasicoincidence in fuzzy topological spaces. In this paper, we will introduce the concept of δ-closure in intuitionistic fuzzy topological spaces, which is a generalization of the δ-closure by Ganguly and Saha.

Inter relations between algebraic boundary and other boundary

“…The compliment of fuzzy 𝛾 open set is fuzzy closed set. [8] A fuzzy subset 𝐴 of fuzzy topological space (𝑋, 𝜏) is said to be fuzzy 𝛿 closed if 𝐴 = 𝑐𝑙(𝐴).…”

Intuitionistic Fuzzy δ-continuous Functions

“…In the previous papers [16,17], we also introduced and investigated some properties of the concept of intuitionistic fuzzy θ-interior and δ-closure in intuitionistic fuzzy topological spaces.…”
