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 ) ,

## Abstract The present paper deals with operators in a Hilbert space related to the theory of quantum groups. Some results on __q__–deformed hyponormal operators extend ones on __q__–normal operators. For a __q__–deformed operator __T__ the Cartesian decomposition of the inverse __T__^–1^ is chara
