Geographic style maps for two‐dimensional lattices

Acta Crystallographica Section A, Volume 79, Issue 1, Page 1-13, January 2023., 2023
Continuous invariant‐based maps visualize for the first time all two‐dimensional lattices extracted from hundreds of thousands of known crystal structures in the Cambridge Structural Database.This paper develops geographic style maps containing two‐dimensional lattices in all known periodic crystals parameterized by recent complete invariants ...

Construction of $k$-Lipschitz Triangular Norms and Conorms From Empirical Data [PDF]

IEEE Transactions on Fuzzy Systems, 2009
This paper examines the practical construction of k -Lipschitz triangular norms and conorms from empirical data. We apply a characterization of such functions based on k-convex additive generators and translate k-convexity of piecewise linear strictly decreasing functions into a simple set of linear inequalities on their coefficients. This is the basis

On a functional equation related to the distributivity of fuzzy implications over triangular norms and conorms [PDF]

Kybernetika, 2014
Summary: Distributivity of fuzzy implications over different fuzzy logic connectives have a very important role to play in efficient inferencing in approximate reasoning, especially in fuzzy control systems. Recently in some considerations connected with these distributivity laws, the following functional equation appeared \[ f(\min(x+y,a))=\min(f(x)+f(

The New Bipolar Intuitionistic Fuzzy Metric Space (NBIFM-Space) with Applications

Axioms
This paper introduces the New Bipolar Intuitionistic Fuzzy Metric Space (NBIFM-space)—a mathematical framework that extends intuitionistic and previously proposed bipolar intuitionistic structures by providing a complete three-component formulation based

Operations on Hesitant Linguistic terms sets Induced By Archimedean Triangular Norms And Conorms [PDF]

International Journal of Computational Intelligence Systems, 2018
The aim of the paper is to discuss some new operations on hesitant fuzzy linguistic terms sets based on Archimedean t-norm and t-conorm. The advantage is that the operations on hesitant fuzzy linguistic terms sets are closed, by studying propositions of the operations on hesitant fuzzy linguistic terms sets, scalar-multiplication addition and power ...

Edelstein Fixed Point Theorem in Neutrosophic Metric Spaces With an Application to an SIR‐Type Epidemic Model

International 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.

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

Discrete Choquet Integral Based on Quasi‐Overlap Functions on Intuitionistic Fuzzy Sets and Its Application in Multi‐Class Ensemble Learning

Journal of Mathematics, Volume 2026, Issue 1, 2026.
As a extension of fuzzy sets, intuitionistic fuzzy sets play an essential part in processing uncertain information. Quasi‐Overlap functions have emerged in recent years as a tool for information aggregation. The combination of intuitionistic fuzzy sets with quasi‐overlap functions offers new methodologies for addressing uncertain information.
