DESCRIPTION - summary of the module content
Dynamical systems are mathematical models of real systems (for example, climate, brain, electronic circuits and lasers) that evolve in time according to definite (deterministic) rules expressed as nonlinear differential equations or iterated maps. Given the set of rules, the purpose of this module is to explain the resulting behaviour. The main questions that dynamical systems theory addresses are: What are the possible long-term behaviours of such systems? How do these depend on initial conditions? How do these depend on system parameters (bifurcations)? In particular, we highlight how seemingly random behaviour (chaos) is possible even in such deterministic systems.
 
Pre-requisite Module: MTH2003 Differential Equations or equivalent
AIMS - intentions of the module

The aim of this module is to expose you to qualitative and quantitative methods for dynamical systems, including nonlinear ordinary differential equations, maps, bifurcations and chaos. The phenomena you will study occur in many physical systems of interest.

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

On successful completion of this module, you should be able to:

Module Specific Skills and Knowledge:

1 Understand the asymptotic behaviour of nonlinear dynamics, including an introduction to important areas of current research in dynamical systems theory, including bifurcations and deterministic chaos;

Discipline Specific Skills and Knowledge:

2 Comprehend mathematical methods that can be used to analyse physical and biological problems.

Personal and Key Transferable/ Employment Skills and  Knowledge:

3 Demonstrate enhanced modelling, problem-solving and computing skills, and will have acquired tools that are widely used in scientific research and modelling;

4 Demonstrate appropriate use of learning resources;

5 Demonstrate self-management and time-management skills.

RE-ASSESSMENT NOTES

If a module is normally assessed entirely by coursework, all referred/deferred assessments will normally be by assignment.

If a module is normally assessed by examination or examination plus coursework, referred and deferred assessment will normally be by examination. For referrals, only the examination will count, a mark of 50% being awarded if the examination is passed. For deferrals, candidates will be awarded the higher of the deferred examination mark or the deferred examination mark combined with the original coursework mark.
