Coupled Anti Q-Fuzzy Subgroups using t-Conorms

open access: yesEarthline Journal of Mathematical Sciences, 2021
In this paper we study coupled anti Q-fuzzy subgroups of G with respect to t-conorm C. We also discuss the union, normal and direct product of them. Moreover, the homomorphic image and pre-image of them is investigated under group homomorphisms and anti homomorphisms.

Edelstein Fixed Point Theorem in Neutrosophic Metric Spaces With an Application to an SIR‐Type Epidemic Model

open access: yesInternational Journal of Differential Equations, Volume 2026, Issue 1, 2026.
In this paper, utilizing the concept of neutrosophic metric spaces proposed by Kirisci and Simsek, we establish a fixed point theorem of Edelstein type within this framework. A numerical example is provided to illustrate the validity of the main result. Furthermore, we present an application to a general SIR‐type epidemic model.

Stability of Various Functional Equations in Non-Archimedean Intuitionistic Fuzzy Normed Spaces

open access: yesDiscrete Dynamics in Nature and Society, 2012
We define and study the concept of non-Archimedean intuitionistic fuzzy normed space by using the idea of t-norm and t-conorm. Furthermore, by using the non-Archimedean intuitionistic fuzzy normed space, we investigate the stability of various functional

Multi-Attribute Decision-Making Method Based on Interval-Valued $q$ -Rung Orthopair Fuzzy Archimedean Muirhead Mean Operators

open access: yesIEEE Access, 2019
Interval-valued q-rung orthopair fuzzy sets (IVq-ROFSs), as a generalization of q-rung orthopair fuzzy sets (q-ROFSs), are the powerful tool for mastering the fuzziness of information.

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.

Incorporating £‐Complex Intuitionistic Fuzzy Set to Sylow Theorems in Group Theory

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
The complex intuitionistic fuzzy (CIF) set is an advanced version of the regular intuitionistic fuzzy set. It is made to better show the uncertainty and complexity that arise in real‐life problems. The grading and nongrading degrees in the CIF set are shown by complex‐valued functions that are defined on the unit disc of the complex plane.

The Intuitionistic Fuzzy Normed Space of Coefficients

open access: yesAbstract and Applied Analysis, 2012
Intuitionistic fuzzy normed space is defined using concepts of t-norm and t-conorm. The concepts of fuzzy completeness, fuzzy minimality, fuzzy biorthogonality, fuzzy basicity, and fuzzy space of coefficients are introduced. Strong completeness of fuzzy

Best Proximity Point Results via 𝒵‐Contractive Mappings in Non‐Archimedean Intuitionistic Fuzzy Metric Spaces

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
In this paper, we introduce a new class of intuitionistic fuzzy contractive (IFC) mappings, termed Z‐contractive mappings, and establish fixed point results in M‐complete intuitionistic fuzzy metric spaces (IFMSs). We further define intuitionistic fuzzy (IF) Z‐proximal contractions to obtain best proximity points for non‐self mappings between two ...

n-Valued Refined Neutrosophic Logic and Its Applications to Physics [PDF]

open access: yes, 2013
In this paper we present a short history of logics: from particular cases of 2-symbol or numerical valued logic to the general case of n-symbol or numerical valued logic.
