Abstract
The aim of the present paper, is to introduce and study a new class of functions which is strictly placed between the class of S_c-continuous functions and the class of semi-continuous function, we call it the class of  S_g-continuous functions. The basic properties, characterizations and  relationships with some other classes of continuity are also obtained.
