Some properties of weak form of $gamma$-semi-open sets

In this paper, we introduce and explore fundamental properties of weak form of $gamma$-semi-open sets namely maximal $gamma$-semi-open sets in topological spaces such as decomposition theorem for maximal $gamma$-semi-open set. Basic properties of intersection of maximal $gamma$-semi-open sets are established, such as the $gamma$-semi-closure law of $gamma$-semi-radical.
