A time-varying analogue of Jensen's formula

Research output: Contribution to journalArticlepeer-review


A generalization of Jensen's formula to operators associated with time-varying systems is presented. Poles and zeros of the transfer function are replaced by elements of the spectrum of two weighted shifts, one associated with the system, the other with its inverse. Exponential dichotomies, together with two operator factorizations play a key role.
