Basic properties of intersection of maximal $gamma$-semi-open sets are established, such as the $gamma$-semi-closure law of $gamma$-semi-radical. %K $gamma$-semi-closed (open) %K $gamma$-semi-closure(interior) %K maximal $gamma$-semi-open %K $gamma$-semi-radical. %U http://journals.math.tku.edu.tw/index.php/TKJM/article/view/771
