| Module Overview |
| The module introduces nonlinear dynamics and chaos for discrete dynamical systems focusing on maps of the interval and circle. |
|
|
| Prerequisites/Co-requisites |
| Desirable: Ordinary Differential Equations. |
|
|
| Module Aims |
|
|
|
| Learning Outcomes |
At the end of the module, a student should be able to:
(1) Analyse simple dynamics (fixed points, periodic points, and their stability) and associated bifurcations
(2) Analyse simple chaotic maps
(3) Recognise the common routes to chaos. |
|
|
| Module Content |
Fixed points and periodic orbits. Stability. Saddle-node and period-doubling bifurcations. Topological transitivity, sensitive dependence on initial conditions. Topological conjugacy and symbolic dynamics. Lyapunov exponents. Period-doubling route to chaos, universality and renormalisation. |

| Methods of Teaching/Learning |
| 3 contact hours per week for 10 weeks. Teaching is by lectures and tutorials. Learning takes place through lectures, tutorials, exercises and background reading. |
