Keywords:
fuzzy contra $\G _{\delta }$-continuity; fuzzy strong $\G _{\delta }$-continuity; fuzzy perfect $\G _{\delta }$-continuity; fuzzy $\G _{\delta }$-compact space; fuzzy $S$-closed space
Summary:
In this paper the concept of fuzzy contra $\G _{\delta }$-continuity in the sense of A. P. Sostak (1985) is introduced. Some interesting properties and characterizations are investigated. Also, some applications to fuzzy compact spaces are established.
