Fuzzy relational Galois connections between fuzzy transitive digraphs De-las-Peñas-Cabrera, Inmaculada Cordero-Ortega, Pablo Muñoz-Velasco, Emilio José Ojeda-Aciego, Manuel De Baets, Bernard Galois, Teoría de We present a fuzzy version of the notion of relational Galois connection between fuzzy transitive directed graphs (fuzzy T-digraphs) on the specific setting in which the underlying algebra of truth values is a complete Heyting algebra. The components of such fuzzy Galois connection are fuzzy relations satisfying certain reasonable properties expressed in terms of the so-called full powering. Moreover, we provide a necessary and sufficient condition under which it is possible to construct a right adjoint for a given fuzzy relation between a fuzzy T-digraph and an unstructured set. 2023-05-08T10:36:29Z 2023-05-08T10:36:29Z 2023-05-06 2022-12-28 journal article I.P.
