Abstract





In this paper, we introduce the concept of fuzzy weakly (r, s)semicontinuous mappings on intuitionistic fuzzy topological spaces in ˇSostak's sense. The relations among various kinds of fuzzy mappings on intuitionistic fuzzy topological spaces in ˇSostak's sense are displayed. The characterization 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.
