Abstract. This paper defines new class of sets called $\gamma$-$P_S$-generalized closed using $\gamma$-$P_S$-open set and $\tau_\gamma$-$P_S$-closure of a set in a topological space. By using this new set, we introduce a new space called $\gamma$-$P_S$- $T_{\frac{1}{2}}$ and define three functions namely $\gamma$-$P_S$-$g$-continuous, $\gamma$-$P_S$-$g$-closed and $\gamma$-$P_S$-$g$-open. Some theoretical results and properties for this space and these functions are obtained. Several examples are given to illustrate some of the results.
