G. B. Navalagi [2] introduced a new class of set called g*s-closed set in topological space. In this paper , we introduce and study the properties of g*s-I closed and open sets in ideal topological spaces. Also by using , g*s-I closed sets we introduce g*s-I continuous functions, g*s-I closed and open maps.
