The use of geometric methods in classical mechanics has proven fruitful, with wide applications in physics and engineering. J.E. Preface to the Second Edition. In addition to the recent textbooks of Arnold, Arnold-Avez, Godbillon, Guillemin-Sternberg, Siegel-Moser, and Souriau, there have been many research articles published. Ratiu Introduction to Mechanics and Symmetry A Basic Exposition of Classical Mechanical Systems "As the name of the book implies, a consistent theme running through the book is that of symmetry. In this book, Professor Marsden concentrates on these geometric aspects, especially on symmetry techniques. Our Stores Are Open Book Annex Membership Educators Gift Cards Stores & Events Help Marsden was honoured "for his outstanding contributions to the study of differential equations in mechanics: he proved the existence of chaos in specific classical differential equations; his work on the momentum map, from abstract foundations to detailed applications, has had great impact." In this book, Professor Marsden concentrates on these geometric aspects, especially on symmetry techniques. In this book, Professor. Marsden and T.S. Publisher's description: The use of geometric methods in classical mechanics has proven fruitful, with wide applications in physics and engineering. Since the first edition of this book appeared in 1967, there has been a great deal of activity in the field of symplectic geometry and Hamiltonian systems.
