In this paper, we study different properties of δ∗-semiopen set. We define the concept of δ∗-semi generalized closed sets and present some characteristics. In addition, as applications to δ∗-semi generalized closed set, we introduce δ∗-semi T1/2 space and obtain some of their basic properties. Moreover, we defined the notions of δ∗-semi symmetric space, δ∗-semi difference sets and δ∗-semi kernel of sets, and investigate some of their fundamental properties. At the latest, some new types of spaces are introduced and the relationships of these spaces are studied

The purpose of this paper is to define and study a new class of set called T*-B-closed sets, and investigating the characteristics of T*-B-closed set. Furthermore, the new type of continuous function is introduce and find some of its basic properties.
