Nonlinear eigenvalue approximation for compact operators
arXiv:1408.3289 · doi:10.1063/1.4936304
Abstract
In \cite{Os} a general spectral approximation theory was developed for compact operators on a Banach space which does not require that the operators be self-adjoint and also provides a first order correction term. Here we extend some of the results of that paper to nonlinear eigenvalue problems. We present examples of its application that arise in electromagnetics.
