The fuzzy metric space based on fuzzy measure

open access: yesOpen Mathematics, 2016
In this paper, we study the relation between a fuzzy measure and a fuzzy metric which is induced by the fuzzy measure. We also discuss some basic properties of the constructed fuzzy metric space.

Existence of fuzzy fixed points of set-valued fuzzy mappings in metric and fuzzy metric spaces

open access: yesAIMS Mathematics, 2023
A contemporary fuzzy technique is employed in the current study to generalize some established and recent findings. For researchers, fixed point (FP) procedures are highly advantageous and appealing mechanisms.

Common Fixed Point Theorems in Non-archimedean Fuzzy Metric Spaces [PDF]

open access: yes, 2012
The aim of this paper is to define the concept of weakly comparable multi-valued mappings. Also we obtain some common fixed point theorems for pairs of weakly comparable multi-valued mappings in ordered non-Archimedean fuzzy metric ...

On the Intuitionistic fuzzy topological (metric and normed) spaces

open access: yes, 2005
In this paper, we define precompact set in intuitionistic fuzzy metric spaces and prove that any subset of an intuitionistic fuzzy metric space is compact if and only if it is precompact and complete.

Best proximity point theorems for α-ψ-proximal contractions in intuitionistic fuzzy metric spaces [PDF]

open access: yes, 2014
The aim of this paper is to introduce and study certain new concepts of α-ψ-proximal contractions in an intuitionistic fuzzy metric space. Then we establish certain best proximity point theorems for such proximal contractions in intuitionistic fuzzy ...

Fixed point and periodic point theorems in fuzzy metric space [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2015
In this paper we prove a periodic point theorem in fuzzy metric space and present some common fixed point theorems for occasionally weakly compatible mappings in fuzzy 3- metric spaces under various conditions.

Median evidential c-means algorithm and its application to community detection [PDF]

open access: yes, 2015
Median clustering is of great value for partitioning relational data. In this paper, a new prototype-based clustering method, called Median Evidential C-Means (MECM), which is an extension of median c-means and median fuzzy c-means on the theoretical ...

(Quantum) Space-Time as a Statistical Geometry of Fuzzy Lumps and the Connection with Random Metric Spaces [PDF]

open access: yes, 2000
We develop a kind of pregeometry consisting of a web of overlapping fuzzy lumps which interact with each other. The individual lumps are understood as certain closely entangled subgraphs (cliques) in a dynamically evolving network which, in a certain ...

Completable fuzzy metric spaces

open access: yesTopology and its Applications, 2017
[EN] In the context of fuzzy metrics in the sense of George and Veeramani, we introduce the concept of stratified fuzzy metric. Many well-known fuzzy metrics are stratified. We prove that stratified strong fuzzy metric spaces (X, M, *) are completable, under the assumption that * is integral (positive).

Meir-Keeler Type Contraction Mappings in $c_0$-triangular Fuzzy Metric Spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2018
Proving  fixed point theorem in a fuzzy metric space is not possible for  Meir-Keeler contractive mapping. For this, we introduce the notion of $c_0$-triangular fuzzy metric space.
