Operator Theory in Krein Spaces and Nonlinear Eigenvalue Problems

This volume contains a collection of recent original research papers in operator theory in Krein spaces, on generalized Nevanlinna functions, which are closely connected with this theory, and on nonlinear eigenvalue problems.Key topics:- spectral theory for normal operators in Krein spaces- perturbation theory for selfadjoint operators in Krein spaces- models for generalized Nevanlinna functions
