Advances in Fuzzy Systems, Volume 2026, Issue 1, 2026.This paper addresses critical limitations in the application of intuitionistic fuzzy sets (IFSs) for complex decision‐making problems under uncertainty. While IFSs offer a robust framework for modeling imprecision through membership, nonmembership, and hesitancy degrees, existing methodologies often simplify the multiplication of intuitionistic fuzzy ...

A Multistage Two‐Sided Matching Model in Interval‐Valued Triangular Fuzzy Environments
Complexity, Volume 2026, Issue 1, 2026.In two‐sided matching problems, accurately quantifying preference intensity using precise numerical values remains a significant challenge due to the inherent complexity and fuzziness of real‐world decision‐making. Moreover, existing research rarely considers the staged dynamics of matching processes across multiple time periods. To address these gaps,

International 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.

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.A linear Diophantine Z‐number Aczel–Alsina t‐norm operator is implemented for solving a linear Diophantine Z‐number problem, along with explaining its reliability, along with the solution derived. Some basic mathematical characteristics of the introduced operator, such as monotonicity, boundedness, and homogeneity, are rigorously deduced mathematically

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.The fuzzy Fredholm integral equation is a fundamental equation that describes a wide range of phenomena in physics, chemistry, and fluid dynamics. Fuzzy neutrosophic numbers offer an effective way to handle the uncertainty in fuzzy Fredholm integral equations, helping identify the most suitable variables and factors for solving them. Therefore, in this
