Abstract:

We introduce a new notion of fuzzy r -interior which is an extension of Chang's fuzzy interior. Using fuzzy r -interior, we define fuzzy r -semiopen sets and fuzzy r -semicontinuous maps which are generalizations of fuzzy semiopen sets and fuzzy semicontinuous maps in Chang's fuzzy topology, respectively. Some basic properties of fuzzy r -semiopen sets and fuzzy r -semicontinuous maps are investigated.
