Fuzzy Set Field and Fuzzy Metric

open access: yesAdvances in Fuzzy Systems, 2014
The notation of fuzzy set field is introduced. A fuzzy metric is redefined on fuzzy set field and on arbitrary fuzzy set in a field. The metric redefined is between fuzzy points and constitutes both fuzziness and crisp property of vector.

Fuzzy metric topology space and manifold [PDF]

open access: yesJournal of Fuzzy Extension and Applications, 2023
This paper, considers the fuzzy topological subsets, fuzzy topological spaces and introduces a novel concept of fuzzy Hausdorff space and fuzzy manifold space in this regards. Based on these concepts, we present a concept of fuzzy metric Hausdorff spaces

On fuzzy contractive mappings in fuzzy metric spaces

open access: yesFuzzy Sets and Systems, 2007
Fixed point theorems for fuzzy contractive mappings due to \textit{V. Gregori} and \textit{A. Sapena} [ibid. 125, No.~2, 245--252 (2002; Zbl 0995.54046)] are extended to Edelstein fuzzy contractive mappings. Convergence properties for fuzzy contractive mappings are studied in fuzzy metric spaces in the sense of \textit{A.

George-Veeramani Fuzzy Metrics Revised [PDF]

open access: yesAxioms, 2018
In this note, we present an alternative approach to the concept of a fuzzy metric, calling it a revised fuzzy metric. In contrast to the traditional approach to the theory of fuzzy metric spaces which is based on the use of a t-norm, we proceed from a t ...

A Duality Relationship Between Fuzzy Partial Metrics and Fuzzy Quasi-Metrics [PDF]

open access: yesMathematics, 2020
In 1994, Matthews introduced the notion of partial metric and established a duality relationship between partial metrics and quasi-metrics defined on a set X.

The Hausdorff Algebra Fuzzy Distance and its Basic Properties [PDF]

open access: yesEngineering and Technology Journal, 2021
In this article we recall the definition of algebra fuzzy metric space and its basic properties. In order to introduced the Hausdorff algebra fuzzy metric from fuzzy compact set to another fuzzy compact set we define the algebra fuzzy distance between ...

The Strong Laws of Large Numbers for Set-Valued Random Variables in Fuzzy Metric Space

open access: yesMathematics, 2021
In this paper, we firstly introduce the definition of the fuzzy metric of sets, and discuss the properties of fuzzy metric induced by the Hausdorff metric.

Fuzzy Approximating Metrics, Approximating Parametrized Metrics and Their Relations With Fuzzy Partial Metrics

open access: yesMathematics, 2023
We generalize the concept of a fuzzy metric by introducing its approximating counterpart in order to make it more appropriate for the study of some problems related to words combinatorics. We establish close relations between fuzzy approximating metrics in case of special $t$-norms and approximating parametrized metrics, discuss some relations between

On Pentagonal Controlled Fuzzy Metric Spaces with an Application to Dynamic Market Equilibrium

open access: yesJournal of Function Spaces, 2022
In this manuscript, we coined pentagonal controlled fuzzy metric spaces and fuzzy controlled hexagonal metric space as generalizations of fuzzy triple controlled metric spaces and fuzzy extended hexagonal b-metric spaces.

Fuzzy Partial Metric Spaces and Fixed Point Theorems

open access: yesMathematics, 2022
Partial metrics constitute a generalization of classical metrics for which self-distance may not be zero. They were introduced by S.G. Matthews in 1994 in order to provide an adequate mathematical framework for the denotational semantics of programming ...
