CALDAS CUEVA, MIGUEL  y  KUMAR SARAF, RATNESH. PRESERVING FUZZY SG-CLOSED SETS. Proyecciones (Antofagasta) [online]. 2001, vol.20, n.2, pp. 127-138. ISSN 0716-0917.  doi: 10.4067/S0716-09172001000200001.

In this paper we consider new weak and stronger forms of fuzzy irresolute and fuzzy semi-closure via the concept Fsg-closed 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 sg-closed sets and to abtain also a characterization of fuzzy semi-T_1/2 spaces

Palabras clave : Fuzzy topological spaces; Fsg-closed sets; fuzzy semi-open sets; fuzzy semi-closed maps; fuzzy irresolute maps.
