Nonlinear System Analysis

This book is devoted to the study of systems whose behavior is governed by nonlinear differential equations. As the subject is a broad one, I have chosen to simplify it and to focus attention on a few problems which play a central role in engineering and physics: illustrative examples are discussed, with applications to particle accelerators, frequency measurement, and masers; and important practical problems, such as synchronization, stability of systems with periodic coefficients, and effect of random disturbances, are analyzed from different viewpoints.
