Nonlinear Spectral Theory

In view of the eminent importance of spectral theory of linear operators in many fields of mathematics and physics, it is not surprising that various attempts have been made to define and study spectra also for nonlinear operators.

This book provides a comprehensive and self-contained treatment of the theory, methods, and applications of nonlinear spectral theory.

The only prerequisite for understanding this book is a modest background in functional analysis and operator theory.

It is addressed to non-specialists who want to get an idea of the development of spectral theory for nonlinear operators in the last 30 years, as well as a glimpse of the diversity of the directions in which current research is moving.
