A Subspace Iteration Algorithm for Fredholm Valued Functions

Engström, Christian LU and Grubišić, Luka (2015) In Mathematical Problems in Engineering 2015.
Abstract

We present an algorithm for approximating an eigensubspace of a spectral component of an analytic Fredholm valued function. Our approach is based on numerical contour integration and the analytic Fredholm theorem. The presented method can be seen as a variant of the FEAST algorithm for infinite dimensional nonlinear eigenvalue problems. Numerical experiments illustrate the performance of the algorithm for polynomial and rational eigenvalue problems.
