Year, pages: 2019, 433 - 436
Keywords: almost normal operators, quasicentral approximate units

About article:

Conjecture 4 of Voiculescu implies that almost normal operators must satisfy a Fuglede-Putnam theorem, namely $[T*,X]$ is a Hilbert-Schmidt operator whenever $[T,X]$ is in the same class for an arbitrary operator $X$. In this note, a partial answer to this question is given, namely when $X\in\mathcal{C}4$, the Fuglede-Putnam theorem holds.
