Perturbations of self-adjoint operators in semifinite von Neumann algebras: Kato-Rosenblum theorem

Qihui Li, Junhao Shen, Rui Shi +1

In the paper, we prove an analogue of the Kato-Rosenblum theorem in a semifinite von Neumann algebra. Let $\mathcal{M}$ be a countably decomposable, properly infinite, semifinite v…
