Fuzzy \(r\)-continuous and fuzzy \(r\)-semicontinuous maps
Summary: 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.
