Abstract
Functorial automata are studied in a concrete category K with structured hom-sets. For each functor F : K → K, which respects this structure, the observability morphisms of F-automata are defined analogously to those of sequential automata. If each F-automaton has an observable reduction, the minimization problem is both much simplified (in fact, translated to the image factorization of the observability morphisms) and made global. We prove that this is the case iff each behavior has a Nerode equivalence. First, we present a survey of the related results on minimal realization and Nerode equivalence.
