A rank-one perturbation result on the spectra of certain operators
Published online by Cambridge University Press: 14 November 2011
Synopsis
In this note we show that certain perturbations, involving rank-one stabilising operators, which correspond to small delays in some feedback control problems, shift a part of the point spectrum of the unperturbed operator into the right-half plane.
