In this paper, we first redefine bifuzzy source and bifuzzy successor operators of fuzzy finite automata(FFAS), as well as discuss their basic properties and their essential relationship. By the result, we study bifuzzy topologies derived from bifuzzy source and bifuzzy successor operators, and prove that they are bifuzzy topology of FFA.Then, base on the result in literature[36],we study l-valued topologies of automata based on quantum logic which derived from source and successor operators. |
