On bounded perturbations of operators of Klein-Gordon type
Peter Jonas
Abstract
A class of nonnegative selfadjoint operators in a Krein space and bounded perturbations of them of a special form are considered. The perturbed operators, which include operators arising from the perturbed Klein-Gordon equation, are definitizable over a neighbourhood of infinity, but not necessarily definitizable.
