Archimedean Heronian mean operators based on complex intuitionistic fuzzy sets and their applications in decision-making problems [PDF]

open access: yesHeliyon
In this article, we derive the Archimedean aggregation operators for complex intuitionistic fuzzy sets, for this, first, we evaluate some Archimedean operational laws based on complex intuitionistic fuzzy values and then we discuss their special cases ...

Non-Archimedean valued quasi-invariant descending at infinity measures

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
Measures with values in non-Archimedean fields, which are quasi-invariant and descending at infinity on topological vector spaces over non-Archimedean fields, are studied in this paper. Moreover, their characteristic functionals are considered.

Nearly $k-th$ Partial Ternary Cubic $*$-Derivations On Non-Archimedean $\ell$-Fuzzy $C^{*}$-Ternary Algebras [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2022
In this paper, we investigate approximations of the $k-th$ partial ternary cubic derivations on non-Archimedean $\ell$-fuzzy Banach ternary algebras and non-Archimedean $\ell$-fuzzy $C^{*}$-ternary algebras.

A classification of hull operators in archimedean lattice-ordered groups with unit [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2020
The category, or class of algebras, in the title is denoted by $\bf W$. A hull operator (ho) in $\bf W$ is a reflection in the category consisting of $\bf W$ objects with only essential embeddings as morphisms.

Joint stochastic simulation of petrophysical properties with elastic attributes based on parametric copula models

open access: yesGeofísica Internacional, 2023
The spatial stochastic co-simulation method based on copulas is a general method that allows simulating variables with any type of dependency and probability distribution functions.

Some ordered hypersemigroups which enter their properties into their σ-classes [PDF]

open access: yesJournal of Hyperstructures, 2017
An important problem in the theory of ordered hypersemigroups is to describe the ordered hypersemigroups which enter their properties into their σ-classes.

Additive $ \rho $-functional inequalities in non-Archimedean 2-normed spaces

open access: yesAIMS Mathematics, 2021
In this paper, we solve the additive $ \rho $-functional inequalities:where $ \rho $ is a fixed non-Archimedean number with $ |\rho| < 1 $. More precisely, we investigate the solutions of these inequalities in non-Archimedean $ 2 $-normed spaces, and ...

Matrix-Tilted Archimedean Copulas

open access: yesRisks, 2021
The new class of matrix-tilted Archimedean copulas is introduced. It combines properties of Archimedean and elliptical copulas by introducing a tilting matrix in the stochastic representation of Archimedean copulas, similar to the Cholesky factor for ...

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.

$\alpha$-Projectable and laterally $\alpha$-complete Archimedean lattice-ordered groups with weak unit via topology [PDF]

open access: yesCategories and General Algebraic Structures with Applications
Let $\bf{W}$ be the category of Archimedean lattice-ordered groups with weak order unit, $\bf{Comp}$ the category of compact Hausdorff spaces, and $\mathbf{W} \xrightarrow{Y} \mathbf{Comp}$ the Yosida functor, which represents a $\bf{W}$-object $A$ as ...
