Some Topological Characteristics of q-Rung Orthopair Fuzzy Metric Space

open access: yesAdvances in Fuzzy Systems
This paper introduced a novel concept of q-rung orthopair fuzzy (q-ROF) metric spaces, in connection with the idea of q-ROF sets, which generalizes well-known concepts of fuzzy metric spaces and intuitionistic fuzzy metric spaces.

On fuzzy contractions in fuzzy metric spaces

open access: yes
The classical Banach principle relies on contractive sequences being Cauchy. Gregori and Sapena (2002) established a fuzzy analogue but required this as an extra hypothesis, leaving it as an open problem. Gregori et al. (2020) later asked whether strictly fuzzy $ψ$-contractive sequences are necessarily Cauchy.

On compactness and G-completeness in fuzzy metric spaces

open access: yes, 2012
[EN] In [Fuzzy Sets and Systems 27 (1988) 385-389], M. Grabiec introduced a notion of completeness for fuzzy metric spaces (in the sense of Kramosil and Michalek) that successfully used to obtain a fuzzy version of Banach´s contraction principle ...

Intuitionistic Fuzzy Partial Metric Spaces

open access: yes
Fuzzy logic is a theory used as an alternative to classical structures in both application and algebraic fields. In particular, there are fuzzy structures in metric spaces and partial metric spaces.

Convexity and hyperconvexity in fuzzy metric space

open access: yes, 2019
© 2019 EUDOXUS PRESS, LLC.In this paper, firstly we give the definion of fuzzy convex metric, in a different way. Then we introduce the concept of hyperconvexity in fuzzy metric space and prove that every fuzzy hyperconvex metric space is complete.

Intuitionistic Fuzzy Metric Groups

open access: yes, 2012
The aim of this paper is to introduce the structure of the called "intuitionsitic fuzzy metric group" and after giving fundamental definitions, to study some properties of intuitionistic fuzzy metric ...
