Following the work of Yorke and Li in 1975, the theory of discrete
dynamical systems and difference equations developed rapidly. The
applications of difference equations also grew rapidly, especially
with the introduction of graphical-interface software that can plot
trajectories, calculate Lyapunov exponents, plot bifurcation
diagrams, and find basins of attraction. Modern computer algebra
systems have opened the door to the use of symbolic calculation for
studying difference equations. This book offers an introduction to
discrete dynamical systems and difference equations and presents
the Dynamica software. Developed by the authors and based on
Mathematica, Dynamica provides an easy-to-use collection of
algebraic, numerical, and graphical tools and techniques that allow
users to quickly gain the ability to: Find and classify the
stability character of equilibrium and periodic points Perform
semicycle analysis of solutions Calculate and visualize invariants
Calculate and visualize Lyapunov functions and numbers Plot
bifurcation diagrams Visualize stable and unstable manifolds
Calculate Box Dimension While it presents the essential theoretical
concepts and results, the book's emphasis is on using the software.
The authors present two sets of Dynamica sessions: one that serves
as a tutorial of the different techniques, the other features case
studies of well-known difference equations. Dynamica and notebooks
corresponding to particular chapters are available for download
from the Internet.
