Fuzzy topological spaces, Fsgclosed sets, Fuzzy semi-open sets, Fuzzy semi-closed maps, Fuzzy irresolute maps.


In this paper we consider new weak and stronger forms of fuzzy irresolute and fuzzy semi-closure via the concept Fsgclosed sets which we call Fap-irresolute maps, Fap-semi-closed maps and contra-fuzzy irresolute and we use it to obtain several results in the literature concerning the preservation of fuzzy sgclosed sets and to obtain also a characterization of fuzzy semiT1/2 spaces.
