Asymptotics of the Spectrum of Nonsmooth Perturbations of Differential Operators of Order $2m$
È. F. Akhmerova Bashkir State University
Abstract:
On a finite closed interval, we obtain the asymptotics of the eigenvalues of a differential operator of order $2m$ perturbed by a differential operator of order $2m-2$ given by a quasidifferential expression. We also consider the case of multiple eigenvalues.
Keywords:
perturbation of a differential operator, spectrum of perturbations, quasidifferential expression, Hilbert space, Dirichlet boundary conditions, resolvent of an operator.
