Ebook: 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
