In this paper, by presenting some notions and theorems, we obtain
different types of fuzzy topologies. In fact, we obtain some
Lowen-type  and Chang-type fuzzy topologies on general fuzzy
automata. To this end, first we define a Kuratowski fuzzy interior
operator which induces a  Lowen-type  fuzzy topology on the  set of
states of a max- min general   fuzzy automaton. Also by  proving
some theorems, we  can  define two  fuzzy closure (two fuzzy
interior) operators on the certain sets related to a  general fuzzy
automaton and then according to these notions we give some theorems
and obtain some different Chang-type fuzzy topologies.
