Introduction to Chaos and Coherence provides a clear introduction to the theory of chaotic systems, with a minimum of mathematical complexity. Used extensively in this color-illustrated book, Lyapunov exponents are convenient tools for exploring models of chaotic systems. Aimed primarily at advanced undergraduate students of physics and applied math, the book will also be of value to anyone with an interest in a mathematical approach to their subject, in particular, chemists, astronomers, and life and earth scientists.
