Abstract.In this paper, we introduce and study the class of semi $\omega^0$-open subsets of a topological space $(X,\tau)$ then we study the semi $\omega^0$-interior and the semi $\omega^0$-closure. Also we define what we call semi $\omega^0$-continuous function and we give several properties and characterizations of this function.
