The Fuzzy Prime Spectrum of Partially Ordered Sets

International Journal of Mathematics and Mathematical Sciences, Volume 2023, Issue 1, 2023., 2023
We study the space of prime fuzzy ideals (and the space of maximal fuzzy ideals as a subspace) equipped with the hull‐kernel topology in partially ordered sets. Mainly, we investigate the conditions for which the fuzzy prime spectrum of a poset is compact, Hausdorff, and normal, respectively.

Applications on Bipolar Vague Soft Sets

Journal of Mathematics, Volume 2023, Issue 1, 2023., 2023
The purpose of this research is to interpolate bipolarity into the definition of the vague soft set. This gives a new more applicable, flexible, and generalized extension of the soft set, the fuzzy soft set, or even the vague soft set, which is the bipolar vague soft set.

Kannan Nonexpansive Mappings on Nakano Sequence Space of Soft Reals with Some Applications

Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
We developed the operators ideal in this article by extending s‐soft reals and a particular space of sequences with soft real numbers. The criteria necessary for the Nakano sequence space of soft real numbers given with the definite function to be prequasi Banach and closed are investigated.

Analysis of T‐Spherical Fuzzy Matrix and Their Application in Multiattribute Decision‐Making Problems

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
The aim of this study is to introduce an innovative concept of T‐spherical fuzzy matrix, which is a hybrid structure of fuzzy matrix and T‐spherical fuzzy set. This article introduces the square T‐spherical fuzzy matrix and constant T‐spherical fuzzy matrix and discusses related properties.

[Retracted] Recognition and Modeling of Crisis Propagation Patterns Combined with Robot Simulation of Social Networks

Journal of Robotics, Volume 2022, Issue 1, 2022., 2022
In order to improve the identification effect of a crisis propagation mode, this paper studies the crisis propagation mode of social networks and uses an intelligent method to identify the crisis propagation mode. Moreover, this paper analyzes and deduces the features of the modulated signal from the two aspects of spectrum and autocorrelation ...

Results on a Chromatic Number of a Bi-polar Fuzzy Complete Bipartite Graphs and Labelling of Tri-Polar Fuzzy Graphs [PDF]

, 2021
The ultimate objective of a piece of research work is to present the labelling of vertices in 3-PFG and labelling of distances in 3-PFG. Also, we characterize some of its properties.

Ordered Quasi(BI)-Γ-Ideals in Ordered Γ-Semirings

Journal of Mathematics, 2019
In this paper, we have defined ordered quasi-Γ-ideals and ordered bi-Γ-ideals in ordered Γ-semirings by defining the relation “≤” in ordered Γ semiring S as a≤b if a+x=b for any a,b,x∈S.

Finite models for positive combinatorial and exponential algebra

Bulletin of the London Mathematical Society, Volume 57, Issue 11, Page 3380-3400, November 2025.
Abstract We use high girth, high chromatic number hypergraphs to show that there are finite models of the equational theory of the semiring of non‐negative integers whose equational theory has no finite axiomatisation, and show this also holds if factorial, fixed base exponentiation and operations for binomial coefficients are adjoined.

Moments, sums of squares, and tropicalization

Journal of the London Mathematical Society, Volume 112, Issue 4, October 2025.
Abstract We use tropicalization to study the duals to cones of nonnegative polynomials and sums of squares on a semialgebraic set S$S$. The truncated cones of moments of measures supported on the set S$S$ are dual to nonnegative polynomials on S$S$, while “pseudomoments” are dual to sums of squares approximations to nonnegative polynomials.
