Less than one implies zero

Felix Schwenninger, Hans Zwart

In this paper we show that from the estimate $sup_{t \geq 0} ∥ C (t) - cos (a t) I ∥ < 1$ we can conclude that $C (t)$ equals $cos (a t) I$ . Here $(C (t))_{t \geq 0}$ is a stro…

Generators with a closure relation

Felix Schwenninger, Hans Zwart

Assume that a block operator of the form $(A_{1} A_{2} 0)$ , acting on the Banach space $X_{1} \times X_{2}$ , generates a contrac…

De Branges-Rovnyak realizations of operator-valued Schur functions on the complex right half-plane

Joseph A. Ball, Mikael Kurula, Olof J. Staffans +1

We give a controllable energy-preserving and an observable co-energy-preserving de Branges-Rovnyak functional model realization of an arbitrary given operator Schur function define…
