Abstract

The relations among various types of continuity of fuzzy proper function on a fuzzy set and at fuzzy point belonging to the fuzzy set in the context of \v{S}ostak's $I$-fuzzy topological spaces are discussed. The projection maps are defined as fuzzy proper functions and their properties are proved.

Keywords: fuzzy proper function, \v{S}ostak's $I$-fuzzy topology, smooth fuzzy continuity
