The New Versions of Hermite–Hadamard Inequalities for Pre-invex Fuzzy-Interval-Valued Mappings via Fuzzy Riemann Integrals

open access: yesInternational Journal of Computational Intelligence Systems, 2022
In this study, we use the fuzzy order relation to show some novel variants of Hermite–Hadamard inequalities for pre-invex fuzzy-interval-valued mappings (F-I∙V-Ms), which we term fuzzy-interval Hermite–Hadamard inequalities and fuzzy-interval Hermite ...

Aggregating Fuzzy Binary Relations and Fuzzy Filters

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2018
The main goal of this paper is to investigate the aggregation of diverse families of binary fuzzy relations, fuzzy filters, and fuzzy lattices. Some links between these families and their images via an aggregation are explored.

FUZZY LATTICES AS FUZZY RELATIONS

open access: yesKorean Journal of Mathematics, 2015
Summary: We define a fuzzy lattice as a fuzzy relation, develop some basic properties of the fuzzy lattice, show that the operations of join and meet in fuzzy lattices are isotone and associative, characterize a fuzzy lattice by its level set, and show that the direct product of two fuzzy lattices is a fuzzy lattice.

Energy and Entropy Measures of Fuzzy Relations for Data Analysis

open access: yesEntropy, 2018
We present a new method for assessing the strength of fuzzy rules with respect to a dataset, based on the measures of the greatest energy and smallest entropy of a fuzzy relation.

Group Decision Making in Conditions of Uncertainty using Fermat’s Weak Fuzzy Graphs and Beal’s Weak Fuzzy Graphs

open access: yesRatio Mathematica, 2022
Decision making is a process of solving problems for choosing the best alternative. The best way to illustrate the alternatives and relation between them is a graph. Developing a fuzzy graph is the convenient way of illutration if there is uncertainty in

Relaxation of isolated quantum systems beyond chaos [PDF]

open access: yes, 2015
In classical statistical mechanics there is a clear correlation between relaxation to equilibrium and chaos. In contrast, for isolated quantum systems this relation is -- to say the least -- fuzzy.

Quantum Entropy for the Fuzzy Sphere and its Monopoles [PDF]

open access: yes, 2014
Using generalized bosons, we construct the fuzzy sphere $S_F^2$ and monopoles on $S_F^2$ in a reducible representation of $SU(2)$. The corresponding quantum states are naturally obtained using the GNS-construction.

Some New Concepts Related to Integral Operators and Inequalities on Coordinates in Fuzzy Fractional Calculus

open access: yesMathematics, 2022
In interval analysis, the fuzzy inclusion relation and the fuzzy order relation are two different concepts. Under the inclusion connection, convexity and non-convexity form a substantial link with various types of inequalities.
