One-dimensional perturbations of unbounded selfadjoint operators with empty spectrum
Anton D. Baranov, Dmitry V. Yakubovich
We study spectral properties of one-dimensional singular perturbations of an unbounded selfadjoint operator and give criteria for the possibility to remove the whole spectrum by a…

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…

G. G. Amosov, A. D. Baranov, V. V. Kapustin
We study perturbations of the semigroup of shifts on with the property that belongs to a certain Schatten-von…
