$\Psi_{\Gamma}-C$ Sets in Ideal Topological Spaces

In this paper, we present a new type of set called $\Psi_{\Gamma}-C$ by using the operator $\Psi_{\Gamma}$. We investigate relationships these sets with some special which were studied in literature. For instance $\theta$-open set, semi $\theta$-semiopen regular $\theta$-closed set. particular, show that is weaker than Furthermore, prove collection closed under arbitrary union. Finally, obtain conclusion forms supratopology.
