摘要：

We investigate the converse of Anderson's theorem on the range-kernel orthogonality of a derivation. In particular, we show that a pair of bounded linear operators on a Hilbert space satisfies the Fuglede-Putnam theorem relative to the ideal of compact operators if and only if it satisfies Anderson's inequality relative to the same ideal.
