T . Clearly, for such operators, T\*kTk= (T\*T)k for all k z 2 . This fact provides a motivation to generalize the class of quasi-normal operators as follows: An operator T is defined to be of class Obviously ( M ; 2 ) contains hyponormal operators. However, we shall show that the class ( M ; k ) ,
