Polynomial Fuzzy Contractions With Applications to SEIRV Epidemic Models

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
In this study, a new family of polynomial‐type fuzzy contractions defined on metric spaces is introduced. Under filtered assumptions, it is demonstrated that such non‐crisp set‐valued operators possess some fixed points. Because of the higher‐order terms polynomial nature of the contractions, a few important corollaries, some of which drop to existing ...

Lacunary statistical convergence of sequences of functions in intuitionistic fuzzy normed space

Journal of Intelligent & Fuzzy Systems, 2014
In this paper we study lacunary statistical convergence of sequences of functions in intuitionistic fuzzy normed spaces. We define concept of lacunary statistical pointwise convergence and lacunary statistical uniform convergence in intuitionistic fuzzy normed spaces and we give some basic properties of these concepts.

Bipolar Hesitant Fuzzy Soft Aggregation Operators and Their Application in Sustainable Warehouse Management

Journal of Mathematics, Volume 2026, Issue 1, 2026.
A sustainable warehouse management system aims to enhance warehouse operations while reducing contamination and resource utilization. Implementation of different policies for a sustainable warehouse management system is not easy because the factors involved are often vague and complex, which makes decision‐making difficult. To address these issues, the

Contraction‐Type Fixed‐Point Theorem for Bivariate/Multivariate Self‐Mappings in Fuzzy Banach Spaces and Hyers–Ulam Stability of Multivariate Functional Equations

Journal of Mathematics, Volume 2026, Issue 1, 2026.
To address the lack of dedicated tools for analyzing the stability of bivariate functional equations in fuzzy environments, this paper investigates fixed‐point theory and functional equation stability in fuzzy Banach spaces (FBSs). First, building on the Bag–Samanta fuzzy norm, we supplement and prove the “proposition on convergence preservation of ...

A Note on Generalized Intuitionistic Fuzzy $ψ$ Normed Linear Space

, 2010
In respect of the definition of intuitionistic fuzzy n-norm \cite{Vijayabalaji}, the definition of generalised intuitionistic fuzzy $ψ$ norm (\, in short GIF$ψ$N \,) is introduced over a linear space and there after a few results on generalized intuitionistic fuzzy $ψ$ normed linear space and finite dimensional generalized intuitionistic fuzzy $ψ ...

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

Journal 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.

A New Fixed‐Point Framework for Nonexpansive and Averaged Mappings in Normed GE‐Algebras

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In this paper, we develop a systematic framework for studying fixed‐point theory in the setting of normed GE‐algebras. Building on the GE‐norm, we introduce and analyze nonexpansive mappings, α‐averaged mappings, and enriched contractions with respect to the quasimetric induced by the GE‐norm.

INTUITIONISTIC FUZZY RECTANGULAR n-NORMED SPACES

Journal of Education for Pure Science
The primary the intention of this article is to present the concept of intuitionistic fuzzy rectangular n-normed space as a generalization of fuzzy rectangular n-normed space and to prove some theorems on this subject. Afterward, we study the concept of ascending family of α-n-norms corresponding to intuitionistic fuzzy rectangular n-norm.
