On some functions concerning fuzzy PG-closed sets

Miguel Caldas Cueva, Govindappa B. Navalagi, Ratnesh K. Saraf


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
