Fuzzy overlapping community quality metrics [PDF]
Social Network Analysis and Mining, 2015 Modularity is widely used to effectively measure the strength of the disjoint community structure found by community detection algorithms. Several overlapping extensions of modularity were proposed to measure the quality of overlapping community structure.

Concerning Fuzzy b-Metric Spaces
Mathematics, 2023 In an article published in 2015, Hussain et al. introduced a notion of a fuzzy b-metric space and obtained some fixed point theorems for this kind of space.

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 ...

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

Relation between b-metric and fuzzy metric spaces [PDF]
Mathematica Moravica, 2018 Summary: In this work we have considered several common fixed point results in \(b\)-metric spaces for weak compatible mappings. By applications of these results we establish some fixed point theorems in \(b\)-fuzzy metric spaces.

Some Remarks on Fuzzy sb-Metric Spaces
Mathematics, 2020 Fuzzy strong b-metrics called here by fuzzy sb-metrics, were introduced recently as a fuzzy version of strong b-metrics. It was shown that open balls in fuzzy sb-metric spaces are open in the induced topology (as different from the case of fuzzy b-metric

Fuzzy Semi-Metric Spaces [PDF]
Mathematics, 2018 The T1-spaces induced by the fuzzy semi-metric spaces endowed with the special kind of triangle inequality are investigated in this paper. The limits in fuzzy semi-metric spaces are also studied to demonstrate the consistency of limit concepts in the induced topologies.

Some properties of fuzzy cone symmetric spaces [PDF]
Journal of Hyperstructures, 2023 In this work, we give a fuzzy analogy of cone symmetric spaces that we call fuzzy cone symmetric spaces. Since these structurere obtained by omitting the triangle inequality in fuzzy cone metric spaces, there are topological degenerations.

IEEE Access, 2020 In this paper, we introduce the notion of generalized fuzzy metric space. Many topological spaces like fuzzy metric spaces, fuzzy $b$ -metric spaces and dislocated fuzzy metric spaces have been generalized by this new generalized fuzzy metric space.

Some New Aspects in the Intuitionistic Fuzzy and Neutrosophic Fixed Point Theory
Journal of Function Spaces, 2022 In this manuscript, we use the concepts of continuous t-norms and continuous t-conorms to introduce some definitions, in which intuitionistic fuzzy rectangular metric spaces, intuitionistic fuzzy rectangular metric-like spaces, intuitionistic fuzzy ...
