Causal C0 operators and feedback stability

Research output: Contribution to journalArticlepeer-review

Abstract

Linear feedback systems, for which the return difference T is a C0 operator are studied. It is shown that if T is essentially unitary then such a system is well posed and stable. All strictly causal C0 operators for which I-T*T is compact are characterized.
