This self-contained introduction to the topic is suitable for graduate students and researchers entering the field for the first time and provides a guide to challenging open problems.In the past several decades the classical PerronFrobenius theory for nonnegative matrices has been extended to obtain remarkably precise and beautiful results for classes of nonlinear maps. This nonlinear PerronFrobenius theory has found significant uses in computer science, mathematical biology, game theory and the study of dynamical systems. This is the first comprehensive and unified introduction to nonlinear PerronFrobenius theory suitable for graduate students and researchers entering the field for the first time. It acquaints the reader with recent developments and provides a guide to challenging open problems. To enhance accessibility, the focus is on finite dimensional nonlinear PerronFrobenius theory, but pointers are provided to infinite dimensional results. Prerequisites are little more than basic real analysis and topology.Preface; 1. What is nonlinear PerronFrobenius theory?; 2. Non-expansiveness and nonlinear PerronFrobenius theory; 3.
