quasi-normal Operator of order n

In this paper, we introduce a new class of operators acting on a complex Hilbert space H which is called quasi-normal operator of order n. An operator T∈B(H) is called quasi-normal operator of order n if  T(T*n Tn)=(T*n Tn)T, where n is positive integer number greater than 1 and T* is the adjoint o...
