Fuzzy Triple Controlled Metric Spaces and Related Fixed Point Results

Journal of Function Spaces, 2021
In this study, we introduce fuzzy triple controlled metric space that generalizes certain fuzzy metric spaces, like fuzzy rectangular metric space, fuzzy rectangular b-metric space, fuzzy b-metric space, and extended fuzzy b-metric space.

On Indistinguishability Operators, Fuzzy Metrics and Modular Metrics [PDF]

Axioms, 2017
The notion of indistinguishability operator was introduced by Trillas, E. in 1982, with the aim of fuzzifying the crisp notion of equivalence relation. Such operators allow for measuring the similarity between objects when there is a limitation on the accuracy of the performed measurement or a certain degree of similarity can be only determined between

Study of temporal intuitionistic fuzzy metric space [PDF]

Journal of Hyperstructures, 2023
In order to create a dynamic measure that describes distances between spatiotemporal points whose positions changeover time as well as between the data represented by these points,a temporal intuitionistic fuzzy metric space is created in this pa-per ...

Derivable Single Valued Neutrosophic Graphs Based on KM-Fuzzy Metric

IEEE Access, 2020
In this paper we consider the concept of KM-fuzzy metric spaces and we introduce a novel concept of KM-single valued neutrosophic metric graphs based on KM-fuzzy metric spaces.

‎Intuitionistic Fuzzy Modular Spaces [PDF]

Transactions on Fuzzy Sets and Systems, 2023
‎After the introduction of the concept of fuzzy sets‎ ‎by Zadeh‎, ‎several researches were conducted on‎ ‎the generalizations of the notion of fuzzy sets‎. ‎There are many viewpoints on the notion of metric space in fuzzy topology‎.

Meir–Keeler Fixed-Point Theorems in Tripled Fuzzy Metric Spaces

Mathematics, 2023
In this paper, we first propose the concept of a family of quasi-G-metric spaces corresponding to the tripled fuzzy metric spaces (or G-fuzzy metric spaces). Using their properties, we give the characterization of tripled fuzzy metrics.

Dealing with non-metric dissimilarities in fuzzy central clustering algorithms [PDF]

, 2008
Clustering is the problem of grouping objects on the basis of a similarity measure among them. Relational clustering methods can be employed when a feature-based representation of the objects is not available, and their description is given in terms of ...

Cauchy Sequences in Fuzzy Metric Spaces and Fixed Point Theorems [PDF]

Sahand Communications in Mathematical Analysis, 2023
In this paper, contractive mappings of \CM{} type in fuzzy metric spaces are studied. A class $\Psi_1$ of gauge functions $\psi:(0,1]\to(0,1]$ such that, for any $r\in(0,1)$, there exists $\rho\in(r,1)$ such that $1-r> \tau >1-\rho$ implies $\psi(\tau ...
