An asymmetric Fuglede-Putnamís theorem for dominant operators
An asymmetric Fuglede-Putnamís theorem for dominant operators andp-hyponormal operators is proved, as a consequence of this result, we obtain that the range of the generalized derivation induced by the above classes of operators is orthogonal to its kernel.
