A perturbation method and the limit-point case of even order symmetric differential expressions
Published online by Cambridge University Press: 14 November 2011
Synopsis
We give a new perturbation theorem for symmetric differential expressions (relatively bounded perturbations, with relative bound 1) and prove with this theorem a new limit-point criterion generalizing earlier results of Schultze. We also obtain some new results in the fourth-order case.
