The Topology of Chaos : Alice in Stretch and Squeezeland

A new approach to understanding nonlinear dynamics and strange attractors The behavior of a physical system may appear irregular or chaotic even when it is completely deterministic and predictable for short periods of time into the future. How does one model the dynamics of a system operating in a chaotic regime?

Beginning with an example of a laser that has been operated under conditions in which it behaved chaotically, the authors convey the methodology of Topological Analysis through detailed chapters on: * Discrete Dynamical Systems: Maps * Continuous Dynamical Systems: Flows * Topological Invariants * Branched Manifolds * The Topological Analysis Program * Fold Mechanisms * Tearing Mechanisms * Unfoldings * Symmetry * Flows in Higher Dimensions * A Program for Dynamical Systems Theory Suitable at the present time for analyzing "strange attractors" that can be embedded in three-dimensional spaces, this groundbreaking approach offers researchers and practitioners in the discipline a complete and satisfying resolution to the fundamental questions of chaotic systems.

Physicists Gilmore (Drexel, U., Philadelphia) and Lefrance (U. of Sciences and Technology, de Lille, France) analyze data generated by a dynamical system operating in a chaotic regime. Specifically, they describe how to extract from chaotic data topological signatures that determine the stretching and squeezing mechanisms that act on flows in phase space and are responsible for generating chaotic data. The topological methods they develop were in response to the challenge of analyzing chaotic data sets generated by a laser operating under conditions in which it behaved chaotically. Annotation c.

Presents an approach to understanding nonlinear dynamics and strange attractors. This book responds to the fundamental challenge of chaotic systems by introducing Topological Analysis which can be used to extract, from chaotic data, the topological signatures that determine the stretching and squeezing mechanisms which act on flows in phase space. Innovative methods for the analysis of chaotic systems, in this second edition completed by a broad introduction for the non expert, additional chapters on embeddings, bounding tori, and the representation theory for strange attractors, and frequently asked questions. Many physical systems displaying chaotic behavior are accurately described by mathematical models derived from well-understood physical principles.
