Error estimates for a Galerkin method with perturbations for spectral problems of the theory of dielectric waveguides

Abstract

© 2016, Pleiades Publishing, Ltd.We obtain error estimates for a Galerkin method with perturbations for approximating eigenvalues and eigenfunctions of one class of abstract spectral problems. Using these results, we get the justification of applying the method for spectral problems of the theory of dielectric waveguides.
