An extension to Fuglede-Putnam’s theorem and orthogonality
Abstract
An asymmetric Fuglede-Putnam’s theorem for w−hyponormal operators and (p,k)−quasihyponormal operator 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.
