On applications of the model spaces to the construction of cocyclic perturbations of the semigroup of shifts on the semiaxis

G. G. Amosov, A. D. Baranov, V. V. Kapustin

We describe a construction of cocyclic perturbations of the semigroup of shifts on the semiaxis by means of the theory of model spaces. It is shown that one can choose an inner fun…

On perturbations of the isometric semigroup of shifts on the semiaxis

G. G. Amosov, A. D. Baranov, V. V. Kapustin

We study perturbations $(τ ~_{t})_{t \geq 0}$ of the semigroup of shifts $(τ_{t})_{t \geq 0}$ on $L^{2} (R_{+})$ with the property that $τ ~_{t} - τ_{t}$ belongs to a certain Schatten-von…
