CALDAS, M; NAVALAGI, G  y  SARAF, R. ON SOME FUNCTIONS CONCERNING FUZZY PG-CLOSED SETS. Proyecciones (Antofagasta) [online]. 2006, vol.25, n.3, pp. 261-270. ISSN 0716-0917.  doi: 10.4067/S0716-09172006000300004.

In this paper we consider new weak and strong forms of fuzzy preirresoluteness and fuzzy pre-closureness via the concept of fuzzy pg-closed sets which we call ap-Fp-irresolute functions, ap-Fp-closed functions and contra fuzzy pre-irresolute functions and we use it to obtain a characterization of fuzzy pre-T_1/2 spaces.

Palabras clave : Fuzzy topological spaces; Fpg-closed sets; fuzzypreopen sets; fuzzy preclosed functions; fuzzy pre-irresolute functions; fuzzy pre-T1/2 spaces.
