Abstract

The concept of a fuzzy topology on a fuzzy set has been introduced in [1]. The aim of this work is to introduce fuzzy δ*-continuity and fuzzy δ**-continuity in this in new situation and to show the relationships between fuzzy continuous functions where we confine our study to some of their types such as, fuzzy δ-continuity, fuzzy continuity, after presenting the definition of a fuzzy topology on a fuzzy set and giving some properties related to it.

Highlights

  • The concept of a fuzzy topology on a fuzzy set has been introduced by Chakrabarty and Ahsanullah [1]

  • We introduce the concepts of a fuzzy δ*-continuity, fuzzy δ**continuity and to show the relationships between types of fuzzy continuous functions in this situation and we examine the validity of the standard results

  • The main purpose of this paper introduces a new concept in fuzzy set theory, namely that of a fuzzy δ*-continuity and fuzzy δ**-continuity

Summary

Introduction

The concept of a fuzzy topology on a fuzzy set has been introduced by Chakrabarty and Ahsanullah [1]. The concepts of fuzzy δ-closed sets, fuzzy δ-open sets fuzzy regular open, fuzzy regular closed, fuzzy δcontinuity and the relation between fuzzy continuity and fuzzy δ-continuity in this new situation was introduced by Zahran [3]. These functions have been characterized and investigated mainly in light of the notions of quasineighborhood, quasi-coincidence. We introduce the concepts of a fuzzy δ*-continuity, fuzzy δ**continuity and to show the relationships between types of fuzzy continuous functions in this situation and we examine the validity of the standard results
