Bochner integrals in ordered vector spaces. [PDF]

open access: yesPositivity (Dordr), 2017
We present a natural way to cover an Archimedean directed ordered vector space $E$ by Banach spaces and extend the notion of Bochner integrability to functions with values in $E$.

Some New Structures in Neutrosophic Metric Spaces [PDF]

open access: yesNeutrosophic Sets and Systems, 2021
Neutrosophic sets deals with inconsistent, indeterminate and imprecise datas. The concept of Neutrosophic Metric Space (NMS) uses the idea of continuous t- norm and continuous t - conorm in intuitionistic fuzzy metric spaces.

Formal balls of Q-categories [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2023
The construction of the formal ball model for metric spaces due to Edalat and Heckmann was generalized to Q-categories by Kostanek and Waszkiewicz, where Q is a commutative and unital quantale.

Archimedean-Compensatory Fuzzy Logic Systems [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2015
The paper aims to define a new kind of logic, referred to as Archimedean-Compensatory Logic, which is constructed from the unification of two different fuzzy logic systems, namely a continuous Archimedean fuzzy logic and a compensatory fuzzy logic.

Aggregation of Indistinguishability Fuzzy Relations Revisited

open access: yesMathematics, 2021
Indistinguishability fuzzy relations were introduced with the aim of providing a fuzzy notion of equivalence relation. Many works have explored their relation to metrics, since they can be interpreted as a kind of measure of similarity and this is, in ...

Differential inequality conditions for dominance between continuous Archimedean t-norms [PDF]

open access: yesMathematical Inequalities & Applications, 2009
Dominance between triangular norms (t-norms) is a versatile relationship. For continuous Archimedean t-norms, dominance can be verified by checking one of many sufficient conditions derived from a generalization of the Mulholland inequality. These conditions pertain to various convexity properties of compositions of additive generators and their ...

Relaxed Indistinguishability Relations and Relaxed Metrics: The Aggregation Problem

open access: yesAxioms, 2022
The main purpose of this paper is to study the relationship between those functions that aggregate relaxed indistinguishability fuzzy relations with respect to a collection of t-norms and those functions that merge relaxed pseudo-metrics, extending the ...

T-Equivalences: The Metric Behavior Revisited

open access: yesMathematics, 2020
Since the notion of T-equivalence, where T is a t-norm, was introduced as a fuzzy generalization of the notion of crisp equivalence relation, many researchers have worked in the study of the metric behavior of such fuzzy relations.

A Duality Relationship Between Fuzzy Partial Metrics and Fuzzy Quasi-Metrics

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.

On Fuzzy Strong $\mathrm{\phi-b-}$Normed Spaces and Fuzzy Strong $\mathrm{\phi-b-}$Normed Algebras [PDF]

open access: yesSahand Communications in Mathematical Analysis
‎Given a continuous Archimedean t-norm and its corresponding continuous additive generator, we introduce a new approach to generate a fuzzy strong $\phi-b-$norm (FS$-\phi-b-$N).
