Subject Knowledge
Aims
This module aims to present an overview of the exciting area of
nonlinear dynamical systems at a level accessible to first
year undergraduates.
Learning Outcomes
Students should understand basic concepts of the
theory of dynamical systems and know typical mechanisms by which
simple systems generate complicated dynamics and fractal structures.
Methods
Class sessions, computer labs, and problem classes
Assessment
Marked problem sheets and lab reports
Subject Skills
Aims
Students should develop skills for modelling simple dynamical
systems and studying their properties.
Learning Outcomes
Students will learn to use the scientific computing environment
MATLAB and to model simple dynamical system within this
environment. In addition to the problem solving skills, the
students will also learn to write a report of the
outcome of their computer experiments. Of the general IT skills,
the students will have the opportunity to learn file creation,
management and storage; use of electronic resourses, such as
internet, email and library catalogues; word processing.
Methods
Class sessions, computer lab sessions, and problem classes
Assessment
Marked problem sheets and lab reports
Explanation of Pre-requisites
From the module MA1002, students should be familiar with
the concepts of vectors and differential equations.
Course Description
The extraordinary visual beauty of fractal images and their
applications in chaos theory have made these endlessly repeating
geometric figures widely familiar. Yet they are more than just
appealing visual patterns and have proved to have wide range of uses.
Chaos dynamics and fractal geometry are important and exciting topics
in contemporary mathematics. This course introduces these topics
using a combination of hands-on computer experimentation and simple
mathematics. Students are led through a series of experiments that
produce fascinating images of Julia sets, Mandelbrot sets, and
fractals. The basic ideas of dynamics - iteration, stability, and
chaos - are illustrated via computer projects.
Syllabus
Dynamical systems. Orbits. Fixed and periodic points.
Graphical analysis. The logistic function.
Stable and unstable orbits. Chaotic orbits. Sensitive dependence on
initial conditions. Lyapunov exponent.
Period doubling bifurcation. Bifurcation diagrams.
Self-similarity and fractals. Cantor sets. Constructing fractals.
Fractal dimension. Julia sets. Parameter spaces and Mandelbrot sets.
Fractal basins of the Newton-Raphson method.
