Semi-continous and semi-closed mappings and semi-connectedness in fuzzy setting

Abstract The aim of the paper is mainly to study and to find different characterizations of semi-continuous and semi-closed mappings between fuzzy topological spaces. The notion of fuzzy semi-open sets is used to define fuzzy Ti-spaces (i = 0, 1, 2) and these spaces are investigated under fuzzy semi-continuity. Finally, fuzzy semi-connectedness is introduced and studied to some extent.
