Download or read book Geometric Methods for Discrete Dynamical Systems written by Robert W. Easton and published by Oxford University Press. This book was released on 1998-02-26 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book looks at dynamics as an iteration process where the output of a function is fed back as an input to determine the evolution of an initial state over time. The theory examines errors which arise from round-off in numerical simulations, from the inexactness of mathematical models used to describe physical processes, and from the effects of external controls. The author provides an introduction accessible to beginning graduate students and emphasizing geometric aspects of the theory. Conley's ideas about rough orbits and chain-recurrence play a central role in the treatment. The book will be a useful reference for mathematicians, scientists, and engineers studying this field, and an ideal text for graduate courses in dynamical systems.
