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.

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

Fréchet fuzzy metric

open access: yesMatematychni Studii, 2022
The aim of this note is to introduce a fuzzy counterpart of the Fréchet distance between curves. We consider both monotonic and non-monotonic case.

Fuzzy partial metric spaces [PDF]

open access: yesInternational Journal of General Systems, 2018
[EN] In this paper we provide a concept of fuzzy partial metric space (X, P, ¿) as an extension to fuzzy setting in the sense of Kramosil and Michalek, of the concept of partial metric due to Matthews. This extension has been defined using the residuum operator ¿¿ associated to a continuous t-norm ¿ and without any extra condition on ¿.

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 ...

Fuzzy Triple Controlled Metric Spaces and Related Fixed Point Results

open access: yesJournal 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.

Study of temporal intuitionistic fuzzy metric space [PDF]

open access: yesJournal 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 ...
