George-Veeramani Fuzzy Metrics Revised

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 ...

Some Topological Character of Neutrosophic normed spaces [PDF]

open access: yesNeutrosophic Sets and Systems, 2021
The concept of neutrosophic normed spaces was introduced by Murat Kirisci* and Necip Simsek [3]. In this paper, by using the compact operator ψ(zj ) and the concept of statistical convergence.

A characterization of tribes with respect to the Łukasiewicz t-norm [PDF]

open access: yes, 1979
summary:We give a complete characterization of tribes with respect to the Łukasiewicz $t$-norm, i. e., of systems of fuzzy sets which are closed with respect to the complement of fuzzy sets and with respect to countably many applications of the ...

Some Inequalities for (α,β)-Normal Operators in Hilbert Spaces [PDF]

open access: yes, 2007
An operator T is called (α,β)-normal (0 ≤ α ≤ 1 ≤ β) if α²T*T ≤ TT* ≤ β²T*T. In this paper, we establish various inequalities between the operator norm and its numerical radius of (α,β)-normal operators in Hilbert spaces.

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

The Properties of Intuitionistic Anti Fuzzy Module t-norm and t-conorm [PDF]

open access: yes, 2022
Zadeh have introduced fuzzy set in 1965 and Atanassov have introduced intuitionistic fuzzy set in 1986 in theirs paper. Now, many of researcher connecting intuitionistic fuzzy set with algebraic structure.

$\lambda$-Statistical Pointwise and Uniform Convergence of Sequences of Functions on Neutrosophic Normed Spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis
This insightful article examines the $\lambda$-statistical convergence of function sequences within neutrosophic norm spaces. It introduces novel concepts such as $\lambda$-statistical pointwise convergence and $\lambda$-statistical uniform convergence ...

Combination of t-norms and their conorms

open access: yesKybernetika, 2023
Summary: Non-negative linear combinations of \(t_{\min}\)-norms and their conorms are used to formulate some decision making problems using systems of max-separable equations and inequalities and optimization problems under constraints described by such systems.

The strongest t-norm for fuzzy metric spaces [PDF]

open access: yes, 2013
summary:In this paper, we prove that for a given positive continuous t-norm there is a fuzzy metric space in the sense of George and Veeramani, for which the given t-norm is the strongest one.
