Fuzzy closure relations
Ojeda Hernández, Manuel; Cabrera, Inma P.; Cordero-Ortega, Pablo
; Muñoz-Velasco, Emilio Jose (Elsevier, 2022-05-25)
The concept of closure operator is key in several branches of mathematics. In this paper, closure operators are extended to relational structures, more specifically to fuzzy relations in the framework of complete fuzzy ... -
Fuzzy closure structures as formal concepts
Ojeda Hernández, Manuel; De-las-Peñas-Cabrera, Inmaculada; Cordero-Ortega, Pablo; Muñoz-Velasco, Emilio Jose (Elsevier, 2022-12-28)
Galois connections seem to be ubiquitous in mathematics. They have been used to model solutions for both pure and application-oriented problems. Throughout the paper, the general framework is a complete fuzzy lattice over ... -
Fuzzy relational Galois connections between fuzzy transitive digraphs
De-las-Peñas-Cabrera, Inmaculada; Cordero-Ortega, Pablo; Muñoz-Velasco, Emilio Jose; Ojeda-Aciego, Manuel; De Baets, Bernard (Elsevier, 2022-12-28)
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 ...
