Galois Connections Between a Fuzzy Preordered Structure and a General Fuzzy Structure.

We continue the study of (isotone) Galois connections, also called adjunctions, in the framework of fuzzy preordered structures, which generalize fuzzy preposets by considering underlying fuzzy equivalence relations. Specifically, we present necessary and sufficient conditions so that, given a mapping f : A → B from a fuzzy preordered structure A = 〈A, ≈A, ρA〉 into a fuzzy structure 〈B, ≈B 〉, it i...
