Fuzzy groups, fuzzy functions and fuzzy equivalence relations
Fuzzy Sets and Systems, 2004 To each fuzzy subgroup a fuzzy equivalence relation is associated and it is proved that a fuzzy subgroup is normal if and only if the operation of the group is compatible with its associated fuzzy equivalence relation. In the definition of fuzzy subgroup only the subset is fuzzy whilst the group operation remains crisp.

Fast Fuzzy Inference in Octave [PDF]
International Journal of Computational Intelligence Systems, 2013 Fuzzy relations are simple mathematical structures that enable a very general representation of fuzzy knowledge, and fuzzy relational calculus offers a powerful machinery for approximate reasoning.

Evaluation method based on fuzzy relations between Dempster–Shafer belief structure
International Journal of Intelligent Systems, 2018 Many relations in the real world can be described by mathematical language. Fuzzy set theory can transform human language into mathematical language and use membership degree function to describe relations between events.

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.

Congruence relation in fuzzy partial hyperalgebras [PDF]
Journal of HyperstructuresIn 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.

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 ...

New Operations of Picture Fuzzy Relations and Fuzzy Comprehensive Evaluation
Symmetry, 2017 In this paper, some new operations and basic properties of picture fuzzy relations are intensively studied. First, a new inclusion relation (called type-2 inclusion relation) of picture fuzzy relations is introduced, as well as the corresponding type-2 ...

Fuzzy Mass Relations for the Higgs [PDF]
, 1995 The non-commutative approach of the standard model produces a relation between the top and the Higgs masses. We show that, for a given top mass, the Higgs mass is constrained to lie in an interval. The length of this interval is of the order of $m_\tau^2/

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
