A Decision‐Making Problem for Smartphone Selection Using Neutrosophic Distance Measures

open access: yesAdvances in Fuzzy Systems, Volume 2026, Issue 1, 2026.
A neutrosophic distance measure using average functions is defined, and the metric axioms are verified by discussing its properties on a neutrosophic structure. Further, the similarity measure’s axioms are also derived for the complement of the proposed distance measure.

Another Note on Paraconsistent Neutrosophic Sets [PDF]

open access: yesSymmetry, 2017
In an earlier paper, we proved that Smarandache’s definition of neutrosophic paraconsistent topology is neither a generalization of Çoker’s intuitionistic fuzzy topology nor a generalization of Smarandache’s neutrosophic topology. Recently, Salama and Alblowi proposed a new definition of neutrosophic topology, that generalizes Çoker’s intuitionistic ...

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.

Neutrosophic Crisp Set & Relations

open access: yesNeutrosophic Sets and Systems, 2014
In a world full of indeterminacy, traditional crisp set with its boundaries of truth and false has not infused itself with the ability of reflecting the reality. Therefore, neutrosophic found its place into contemporary research as an alternative representation of the real world.

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

open access: yesInternational 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 ...

Divergence Measure Of Neutrosophic Sets And Applications

open access: yesNeutrosophic Sets and Systems, 2018
In this paper, we first propose the concept of divergence measure on neutrosophic sets. We also providesome formulas for the divergence measure for neutrosophic sets. After that, we investigate the properties of proposed neutrosophic divergence measure. Finally, we also apply these formulas in medical problem and the classification problem.

New Similarity and Entropy Measures of Interval Neutrosophic Sets with Applications in Multi-Attribute Decision-Making

open access: yesSymmetry, 2019
Information measures play an important role in the interval neutrosophic sets (INS) theory. The main purpose of this paper is to study the similarity and entropy of INS and its application in multi-attribute decision-making.

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

open access: yesInternational 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

New Neutrosophic Sets Via Neutrosophic Topological Spaces

open access: yes, 2018
In Geographical information systems (GIS) there is a need to model spatial regions with indeterminate boundary and under indeterminacy. The purpose of this chapter is to construct the basic concepts of the so-called "neutrosophic sets via neutrosophic topological spaces (NTs)".

(m,a,n)-Fuzzy Neutrosophic Sets and Their Topological Structure [PDF]

open access: yesNeutrosophic Sets and Systems
In this paper the concept of (m, a, n)-fuzzy neutrosophic set is introduced and its basic operations are studied. It is shown by examples that the class of (m, a, n)-fuzzy neutrosophic sets properly contains the class of q-rung orthopair neutrosophic ...
