In this paper, I*-sequential topology is defined on a topological
space (X, τ) by considering any ideal I which is a family of subset of natural
numbers N. It has been proven that I∗-sequential topology is finer than
I-sequential topology. In connection with this fact, the notions I*-continuity
and I∗-sequential continuity are shown to be coincided in this topology. Additionally,
I*-sequential compactness and related notions are defined and investigated.
