On operators with unitary ϱ-dilations

Name: Work Video:
Duration: 3 min 30 s
Description: We show a polynomially boundend operator T is similar to a unitary operator if there is a singular unitary operator W and an injection X such that XT = WX. If, in addition, T is of class $C_ϱ$, then T itself is unitary.
