'The classical mechanics of systems of finitely many point particles belongs to the bedrock of theoretical physics every physicist has to be familiar with. Giorgilli's book on Hamiltonian mechanics is a treasure chest. It conveys the author's profound knowledge of the history of the subject and provides a pedagogical exposition of the basic mathematical techniques. Very many important examples of systems are discussed, and the reader is guided towards fairly recent and new developments in this important subject. This book will become a classic.' Jurg Froehlich, ETH Zurich
'This is an impressive book by one of the protagonists of the modern theory of dynamical systems. It contains the basic steps of the Hamiltonian theory, but it emphasizes the modern developments of the theory that started with Poincare and Birkhoff, reaching the study of chaos. The book has two important advantages: it gives the successive steps needed by a beginner who enters this field, up to its most recent developments, and it provides a remarkable historical account of the developments of the theory. Giorgilli introduced many new ideas in the theory of dynamical systems, but he presents the new developments in a systematic way without emphasizing his own contributions. This book will be of great value for anyone interested in dynamics, and it is absolutely necessary for any library in Physics, Astronomy and related fields.' George Contopoulos, Academy of Athens
'This is a book that the reader will refer to over and over again: it provides a theoretical and practical framework for understanding Hamiltonian formalism and classical perturbation theory. It contains a readable complete proof of the most important results in the field (Kolmogorov-Arnold-Moser theorem and Nekhoroshev's theorem) as well as their applications to the fundamental problems of celestial mechanics. It also explains how small divisors are at the origin of the divergence of perturbation series and Poincare's discovery of homoclinic intersections and of chaotic behavior in near-to-integrable systems. What a remarkably useful and exciting book!' Stefano Marmi, Scuola Normale Superiore, Pisa
'This amazing book, written by a prominent master of the theory of Hamiltonian systems, is a wonderful gift for anyone interested in Classical Dynamics, from a novice student to a sophisticated expert. The author, together with the reader, goes from the definition of canonical equations to such shining peaks as the Kolmogorov theorem on invariant tori and the Nekhoroshev theorem on exponential stability (with complete proofs, and for each of these fundamental theorems two entirely different proofs are presented!). Carefully selected examples and exercises and historical digressions greatly facilitate learning the material and turn reading the book into an intellectual festivity.' Mikhail Sevryuk, Semenov Federal Research Center of Chemical Physics, Moscow
'Giorgilli builds up the whole architecture of Hamiltonian Dynamics chapter by chapter in a delightful succession of ideas with many examples. This book will certainly become an essential reference for basic and for advanced courses and it will also be a source of inspiration for experts in the field.' Angel Jorba, University of Barcelona
'This book is an excellent and exhaustive treatise on Hamiltonian systems aimed at both students and researchers, which collects in great detail the classical results and contains a very accurate description of the theory of perturbations. It is a reference book on constructive methods, which are successfully applied throughout the book in many examples, most notably those of Celestial Mechanics.' Amadeu Delshams, BarcelonaTech
