Fuglede-Putnam theorem for w-hyponormal or class y operators

An asymmetric Fuglede-Putnam's Theorem for w--hyponormal operators and class Y 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.
