Asymmetric Fuglede Putnam&⋕39;s Theorem for operators reduced by their eigenspaces. FILOMATFILOMAT. 2017.
AbstractFuglede-Putnam Theorem have been proved for a considerably large number of class of operators. In this paper by using the spectral theory, we obtain a theoretical and general framework from which Fuglede-Putnam theorem may be promptly established for many classes of operators.
