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
