FUZZY WEAKLY (r; s)-SEMICONTINUOUS MAPPINGS

In this paper, we introduce the concept of fuzzy weakly (r; s)-semicontinuous mappings on intuitionistic fuzzy topological spaces in ·Sostak s sense. The relations among various kinds of fuzzy mappings on intuitionistic fuzzy topological spaces in ·Sostak s sense are displayed. The characteriza- tion for the fuzzy weakly (r; s) -semicontinuous mapping is obtained. Also, we introduce the notion of fuzzy weakly (r; s)-semicontinuous mappings at a given intuitionistic fuzzy point. The relation between fuzzy weakly (r; s)-semicontinuous mappings and fuzzy weakly (r; s)-semicontinuous mappings at an intuitionistic fuzzy point is discussed.
