This book was awarded the Ferran Sunyier i Balaguer Prize for 2001, and I am sure that it will be a very useful resource not only for researchers in this area but also for those who want to obtain the benefits of using this approach in applications. <p>a Bulletin of the American Mathematical Society <p> This excellent book reflects the authors' experience in [the] exploration of the role of symmetry ina ]pattern formation in nonlinear dynamics over the past fifteen years. The selection of the material, logical structure of the monograph and presentation are perfect. Numerous historical comments, carefully selected examples accompanied [by] helpful diagrams, graphs and illustrations, valuable bibliographic references combined with panoramic introductory pieces opening each chapter, and rigorous mathematical exposition make this text enjoyable reading for everyone interested in the role played by symmetries in nonlinear dynamics and equivariant bifurcation theory. Furthermore, the book can serve as a superb sample of mathematical writing. <p>a Zentralblatt Math <p> The title gives the program of this nice book: the world seen from the symmetry point of view. In the past years we have seen a great number of papers explaining experiments and other observations in science using bifurcation and dynamical systems theory in the context of symmetry breaking. The authors of this book have shaped this developmenta ]. The theory which is presenteda ]is illustrated by many diagrams and figuresa ]. Of course in this book the authors cannot give complete proofs of all relevant statements. But this reflects the spirit of the book, which is to provide experiments, describe examples and give(some) explanations of a part of modern mathematics following one central theme: symmetrya ]. <p>[The] rich collection of examples makes the booka ]extremely useful for motivation and for spreading the ideas to a large community. This [review] is far from complete and cannot reflect the authors' unique way of presenting examples, asking questions, giving answers or forming an intuition. <p>a Mathematical Reviews
