The Transition to Chaos : In Conservative Classical Systems: Quantum Manifestations The subjects treated here are part of an active and rapidly growing field of research that touches on the foundations of physics and chemistry. Specifically the book presents in as simple and coherent a manner as possible the basic mechanisms that determine the dynamical evolution of both classical and quantum systems in sufficient generality to include nonlinear phenomena. The book begins with a discussion of Noethers Theorem integrability KAM theory and a definition of chaotic behavior; it continues with a detailed discussion of area preserving maps integrable quantum systems spectral properties path integrals and periodically driven systems; and concludes by showing how to apply the ideas to stochastic systems. Appendices fill in much of the necessary mathematical background. Based on courses given at Universities in California Texas and China the book will be useful both as a text and as a reference. The presentation is complete and there are extensive references to the current research literature. Problems at the ends of the chapters will help students clarify their understanding of the concepts
