Abstract

Let Ω be a complete residuated lattice. By SetF(Ω) we denote a category of sets with similarity relations (A,δ) with values in Ω. We investigate an interpretation of a first order predicate fuzzy logic in a model based on objects of this category SetF(Ω). A notion of a fuzzy set in this category is introduced and interpretation of formulas as fuzzy sets are defined. Characteristic morphisms are defined for such fuzzy sets and relationship between interpretation by fuzzy sets and interpretation defined by characteristic morphisms are investigated.
