this book provides the first self-contained comprehensive
exposition of the theory of dynamical systems as a core
mathematical discipline closely intertwined with most of the main
areas of mathematics. the authors introduce and rigorously develop
the theory while providing researchers interested in applications
with fundamental tools and paradigms.
the book begins with a discussion of several elementary but
fundamental examples. these are used to formulate a program for the
general study of asymptotic properties and to introduce the
principal theoretical concepts and methods. the main theme of the
second part of the book is the interplay between local analysis
near individual orbits and the global complexity of the orbit
structure. the third and fourth parts develop in depth the theories
of !ow-dimensional dynamical systems and hyperbolic dynamical
systems.
the book is aimed at students and researchers in mathematics at
all levels from ad-vanced undergraduate up. scientists and
engineers working in applied dynamics, non-linear science, and
chaos will also find many fresh insights in this concrete and clear
presentation. it contains more than four hundred systematic
exercises.
