TY: JOUR T1 - Introducing synchrony in fuzzy automata A1 - Gomes, Leandro A1 - Madeira, Alexandre A1 - Barbosa, Luis Soares N2 - This paper introduces a sort of automata and associated languages, often arising in modelling natural phenomena, in which both vagueness and simultaneity are taken as first class citizens. This requires a fuzzy semantics assigned to transitions and a precise notion of a synchronous product to enforce the simultaneous occurrence of actions. The expected relationships between automata and languages are revisited in this setting; in particular it is shown that any subset of a fuzzy synchronous language with the suitable signature forms a synchronous Kleene algebra.
