Transitive Closures of Ternary Fuzzy Relations

International Journal of Computational Intelligence Systems, 2021
Recently, we have introduced six types of composition of ternary fuzzy relations. These compositions are close in spirit to the composition of binary fuzzy relations.

Aggregation of Indistinguishability Fuzzy Relations Revisited

Mathematics, 2021
Indistinguishability fuzzy relations were introduced with the aim of providing a fuzzy notion of equivalence relation. Many works have explored their relation to metrics, since they can be interpreted as a kind of measure of similarity and this is, in ...

Two-Dimensional Fuzzy Spatial Relations: A New Way of Computing and Representation

Advances in Fuzzy Systems, 2012
Fuzziness is found everywhere, in modeling spatial relations, fuzziness is found at object level as well as in relation semantics. Commonly, fuzzy topological relations are computed between fuzzy objects. Fuzziness in relation semantics is represented by

Generalising KAT to Verify Weighted Computations

Scientific Annals of Computer Science, 2019
Kleene algebra with tests (KAT) was introduced as an algebraic structure to model and reason about classic imperative programs, i.e. sequences of discrete transitions guarded by Boolean tests.

Compatibility measurement-based group decision making with interval fuzzy preference relations

Journal of Algorithms & Computational Technology, 2017
In this paper, we put forward a ratio-based compatibility degree between any two ]0,1[-valued interval numbers to measure how proximate they approach to each other.

Functional Partial Fuzzy Relations

Mathematics, 2021
We study fuzzy relations that satisfy the functionality property and that their membership functions can be partial functions. Such fuzzy relations are called partial fuzzy relations, and the variable-domain fuzzy set theory is a framework that provides ...

Relaxed Indistinguishability Relations and Relaxed Metrics: The Aggregation Problem

Axioms, 2022
The main purpose of this paper is to study the relationship between those functions that aggregate relaxed indistinguishability fuzzy relations with respect to a collection of t-norms and those functions that merge relaxed pseudo-metrics, extending the ...

Congruence relation in fuzzy partial hyperalgebras [PDF]

Journal of Hyperstructures
In this paper, we begin by introducing the concept of fuzzy partial hyperalgebra and exploring the relationships between congruence relations and strong congruence relations within this framework.

Fuzzified Matrix Space and Solvability of Matrix Equations

Axioms
A fuzzified matrix space consists of a collection of matrices with a fuzzy structure, modeling the cases of uncertainty on the part of values of different matrices, including the uncertainty of the very existence of matrices with the given values.

FUZZY LATTICES AS FUZZY RELATIONS

Korean 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.
