ACM30190 Dynamical Systems

Academic Year 2021/2022

This module provides an introduction to the theory of dynamical systems leading up to the concept of chaos.

The course starts by considering one-dimensional flow, identifying fixed points, classifying stability, and introducing the saddle-node, transcritical and pitchfork bifurcations.

We then progress to two-dimensional flows, and discuss classification of linear systems, methods of plotting the phase plane, and limit cycles. We will consider the behaviour of conservative systems, reversible systems and Liénard systems and discuss the Poincaré-Bedixson theorem and Hopf bifurcations.

Finally, we will look at chaotic systems, and study one-dimensional maps, fractals and strange attractors.

Learning Outcomes:

On completion of this module students should be able to:
- identify fixed points of nonlinear systems.

- identify bifurcation points.
- classify and describe different types of bifurcations.
- identify limit points and limit cycles and apply the Poincare Bendixson theorem, Liapunov functions and Liénard's theorem.
- discuss chaotic systems and give some examples.

Feedback Strategy/Strategies

• Feedback individually to students, post-assessment
• Group/class feedback, post-assessment
• Online automated feedback

How will my Feedback be Delivered?

In-class activities and weekly quizzes provide students with regular feedback. Individual feedback will be given on assignments and class tests. The assessment structure is designed such that students will receive feedback on their previous assessment prior to submitting the next.
