Strongly Lacunary Ideal Convergence of Sequences of Functions

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
In the present paper, we introduce the notions of strongly lacunary convergence, strongly lacunary I‐convergence, and strongly lacunary I∗‐convergence for sequences of functions, while analyzing the interrelations among these established concepts. Furthermore, we formulate the definitions of strongly lacunary I‐Cauchy and strongly lacunary I∗‐Cauchy ...

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

Properties of Supra Equivalent Subsets and Their Applications via Supra R0 Spaces

Journal of Mathematics, Volume 2026, Issue 1, 2026.
The extension of a topology by weakening its axioms is highly significant, as it generates new frameworks that preserve certain topological properties while allowing for the modeling of several practical problems. In this paper, we introduce the concept of supra equivalent subsets in the framework of a supra topological space and look at the main ...

Adding Neutrosophic Topological Indices to Graphs for Social Network Analysis

Journal of Mathematics, Volume 2026, Issue 1, 2026.
Topological indices are widely used in graph analysis under uncertainty. However, existing fuzzy and intuitionistic approaches do not fully capture indeterminacy. Neutrosophic graphs, with their truth, indeterminacy and falsity components, offer a more comprehensive framework. Despite the frequent use of the Wiener index in neutrosophic contexts, other

Structural Analysis of Two‐Fold Algebraic Systems Defined Over Fuzzy and Antifuzzy Groups

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This study examines the structural properties of two‐fold algebras defined over fuzzy groups and antifuzzy groups. The corresponding two‐fold binary operations are introduced, and their fundamental algebraic features, such as associativity, identity elements, inverses, and finite order elements, are analyzed. In addition, several related substructures,

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 ...

Intuitionistic Fuzzy Normed Subrings and Intuitionistic Fuzzy Normed Ideals

, 2020
The main goal of this paper is to introduce the notion of intuitionistic fuzzy normed rings and to establish basic properties related to it. We extend normed rings by incorporating the idea of intuitionistic fuzzy to normed rings, we develop a new ...

A Tychonoff theorem in intuitionistic fuzzy topological spaces [PDF]

, 2004
The purpose of this paper is to prove a Tychonoff theorem in the so-called “intuitionistic fuzzy topological spaces.” After giving the fundamental definitions, such as the definitions of intuitionistic fuzzy set, intuitionistic fuzzy topology ...
