    Description / Table of Contents: This book is an in-depth and broad text on the subject of chaos in dynamical systems. It is intended to serve both as a graduate course text for science and engineering students, and as a reference and introduction to the subject for researchers. Within the past decades scientists, mathematicians and engineers have realized that a large variety of systems exhibit complicated evolution with time. This complicated behavior, called chaos, occurs so frequently that it has become important for the workers in many disciplines to have a good grasp of the fundamentals and basic tools of the emerging science of chaotic dynamics. Topics in the book include: attractors; basins of attraction; one-dimensional maps; fractals; natural measure; strange attractors; delay coordinate embedding; fat fractals; Hausdorff dimension; symbolic dynamics; stable and unstable manifolds; Lyapunov exponents; metric and topological entropy; controlling chaos; chaotic transients; fractal basin boundaries; chaotic scattering; quasiperiodicity; Hamiltonian systems; KAM tori; period doubling cascades; the intermittency transition to chaos; crises; bifurcations to chaos in scattering problems and in fractal basin boundaries; the characterization of dynamics by unstable periodic orbits; and quantum chaos in time-independent bounded systems, as well as in temporally kicked and scattering problems. Homework problems are also included throughout the book. - This book will be of value to advanced undergraduates and graduate students in science, engineering and mathematics taking courses in chaotic dynamics, as well as to researchers interested in the subject.

    Notes: This paper numerically investigates the magnetohydrodynamic equations in three dimensions with periodic boundary conditions in a parameter range where a forced fluid flow is chaotic. It is found that the transition to dynamo action, whereby the magnetic field is sustained by interaction with the forced flow, is a blowout bifurcation. The blowout bifurcation is typified by bursting behavior, or "on-off intermittency." In particular, near the transition there are short, intermittently occurring bursts of strong magnetic field activity where the total magnetic energy is comparable to the total flow kinetic energy. Between these bursts the magnetic energy is very small. As one approaches the transition from the dynamo-active side, the time between bursts becomes longer and longer, approaching infinity at the transition. Numerical verification is given for the presence of signature scaling laws in numerical computations utilizing a pseudospectral model with triply periodic boundary conditions. This work implies specific testable predictions for experimental dynamos. © 2001 American Institute of Physics.

    Notes: [Auszug] In chaotic scattering, an initially freely moving orbit (such as that of an atom or a star) enters a scattering region and evolves chaotically for a period of time before it escapes and returns to free motion. We have looked at cases in which escape can occur in three or more distinct ways. ...

    Notes: [Auszug] Soon after the crowd streamed on to London's Millennium Bridge on the day it opened, the bridge started to sway from side to side: many pedestrians fell spontaneously into step with the bridge's vibrations, inadvertently amplifying them. Here we model this unexpected and now notorious ...

    Notes: This paper reviews results on fast kinematic dynamo theory, emphasizing the recent realization that Lagrangian chaos of the underlying flow is the key element for understanding of the problem. Simple models for singular behavior of the magnetic field in the large magnetic Reynolds number limit are described and used to illustrate the tendency for fractal magnetic field distributions with extreme cancellation properties. The relation of ergodic properties of the chaotic flow to properties of the dynamo (e.g., growth rate, fractal dimension) are also discussed. © 1998 American Institute of Physics.

    Notes: This paper tests previous heuristically derived general theoretical results for the fast kinematic dynamo instability of a smooth, chaotic flow by comparison of the theoretical results with numerical computations on a particular class of model flows. The class of chaotic flows studied allows very efficient high resolution computation. It is shown that an initial spatially uniform magnetic field undergoes two phases of growth, one before and one after the diffusion scale has been reached. Fast dynamo action is obtained for large magnetic Reynolds number Rm. The initial exponential growth rate of moments of the magnetic field, the long time dynamo growth rate, and multifractal dimension spectra of the magnetic fields are calculated from theory using the numerically determined finite time Lyapunov exponent probability distribution of the flow and the cancellation exponent. All these results are numerically tested by generating a quasi-two-dimensional dynamo at magnetic Reynolds number Rm of order up to 105. © 1996 American Institute of Physics.

    Notes: The problem of directing a trajectory of a chaotic dynamical system to a target has been previously considered, and it has been shown that chaos allows targeting using only small controls. In this paper we consider targeting in a Hamiltonian system, whose phase space contains a mixture of regular quasi-periodic and chaotic regions. A multistep forward–backward method targeting strategic intermediate points is found to be efficient and robust. It takes full advantage of the phase space structure and is believed to yield optimal transport times. It is robust under the influence of small noise and small modeling errors and recovers from temporary loss of control. Two illustrative examples, the standard map and the restricted circular three body problem, are presented. (The latter corresponds to motion of a space probe in the presence of the earth and the moon.) Comparisons are made of our method to other targeting strategies. © 1997 American Institute of Physics.
