In this paper, we introduce the class of Posi-Class (Q) operator acting on a complex Hilbert space H to H. An operator T ? L(H) is said to be Posi-Class (Q) if T *2P T 2 = (T*T )2 for a positive operator P ? L(H) . We look at some nice properties that are associated with this class.
Class (Q), Almost-Class (Q) operators , Posi-Class (Q) and Posinormal operators.
