Resumen de Nonlinear eigenvalue problems and contour integrals

Marc van Barel, Peter Kravanja

• In this paper Beyn’s algorithm for solving nonlinear eigenvalue problems is given a new interpretation and a variant is designed in which the required information is extracted via the canonical polyadic decomposition of a Hankel tensor. A numerical example shows that the choice of the filter function is very important, particularly with respect to where it is positioned in the complex plane.
