In this paper, we introduce the class of *D-Operator a bounded linear operator T is said to be a *D-Operator if T ?2(T D)2 = (T D T ?)2. we investigate the basic properties of this class and also show that this class is closed under strong operator topology.
D-Operator, *D-Operator, Class (Q), Almost Class (Q), (?, ?)-Class (Q), Normal operators, n-Normal, n-D-Operator operators.
