From the reviews of the second edition: This is a very substantial revision of the author's original textbook published in 1990. It does not only contain much new material, for instance on invariant manifold theory and normal forms, it has also been restructured. ... The presentation is intended for advanced undergraduates ... ... Read more. This second edition ... will serve as one of the most eminent introductions to the geometric theory of dynamical systems. (R. Burger, Monatshefte fur Mathematik, Vol. 145 (4), 2005) This is an extensively rewritten version of the first edition which appeared in 1990, taking into account the many changes in the subject during the intervening time period. ... The book is suitable for use as a textbook for graduate courses in applied mathematics or cognate fields. It is written in a readable style, with considerable motivation and many insightful examples. ... Overall, the book provides a very accessible, up-to-date and comprehensive introduction to applied dynamical systems. (P.E. Kloeden, ZAMM-Zeitschrift fur Angewandte Mathematik und Mechanik, Vol. 85 (1), 2005) The second edition of this popular text ... is an encyclopedic introduction to dynamical systems theory and applications that includes substantial revisions and new material. It should be on the reading list of every student of the subject ... . Also, the new organization makes the book more suitable as a textbook that can be used in graduate courses. This book will also be a useful reference for applied scientists ... as well as a guide to the literature. (Carmen Chicone, Mathematical Reviews, 2004h) This volume includes a significant amount of new material. ... Each chapter starts with a narrative ... and ends with a large collection of excellent exercises. ... An extensive bibliography ... provide a useful guide for future study. ... This is a highly recommended book for advanced undergraduate and first-year graduate students. It contains most of the necessary mathematical tools ... to apply the results of the subject to problems in the physical and engineering sciences. (Tibor Krisztin, Acta Scientiarum Mathematicarum, Vol. 75, 2009) It is certainly one of the most complete introductory textbooks about dynamical systems, though no single book can be really complete. ... Some chapters can certainly be used as a course text for a master's course, but the whole book is to thick for a single course. ... a suitable first text for Ph.D. students who want to do research in dynamical systems, and a useful reference work for more experienced people. I definitely enjoyed reading this book and can only recommend it. (Kurt Lust, Bulletin of the Belgian Mathematical Society, Vol. 15 (1), 2008) Show Less
