Counterpart of Boundary Topological Operators Within the Framework of Primal Topological Spaces

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
In this paper, we aim to introduce a new operator via primal topological spaces, called the ⊤‐operator, and look into its basic properties. Among the interesting results we prove, for every subset D, we have (1) D⊤⊆Fr(D), where Fr is the topological boundary operator, and (2) D⊤ = ∅, whenever either a subset D or its complement lies outside the given ...

Development of Linear Diophantine Fuzzy Z‐Number Aczel–Alsina Aggregation Operators and Their Use in a Hybrid MCDM Framework for Medical Diagnosis

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

On the Double of the Laplace–Mayan Transformation and Its Properties With Applications

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
In this study, we have been able to extend the concept of a Mayan integral transform for a one‐dimensional Mayan integral transform to a two dimensional, also called the double Laplace–Mayan integral transform. Some key concepts, definitions, and theorems for the double Laplace–Mayan transform have also been defined in this study.

A Neural Network‐Based Decision Framework Utilizing Large Language Models and Neutrosophic Sets for Sustainable Supplier Selection

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
Sustainable supplier selection is a high‐impact decision problem in which organizations must jointly evaluate economic performance, environmental impact, and social responsibility under heterogeneous stakeholder preferences, asymmetric decision authority, and predominantly linguistic assessments. Conventional multiattribute group decision‐making (MAGDM)

A Novel Neutrosophic Recommender System Model Using Entropy Theory and Collaborative Filtering Algorithm

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
User behavior data used in recommender systems are frequently inconsistent, uncertain, and hesitant, making it challenging to model using common traditional techniques. Fuzzy logic, known for its ability to handle uncertainty, has therefore been widely adopted.

Single-Valued Neutrosophic Graph with Heptapartitioend Structure [PDF]

Neutrosophic Sets and Systems
This study applies single-valued neutrosophic sets, which extend the frameworks of fuzzy and intuitionistic fuzzy sets, to graph theory. We introduce a new category of graphs called Single-Valued Heptapartitioned Neutrosophic Graphs (SVHNG) and ...

An Integrated T‐Spherical Fuzzy 2‐Tuple Linguistic WASPAS Framework With Hamy Mean Aggregation for Wildlife Conservation Planning

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.
Due to the inherent uncertainty in selecting a best alternative, T‐spherical fuzzy 2‐tuple linguistic (T‐SF2TL) sets will be an advantageous method for decision makers (DMs) to assist their evaluations within T‐SF2TL framework. The objective of this study is to establish weighted Hamy mean (WHM) and weighted dual Hamy mean (WDHM) operators within the ...
