On completion of this module, a student should be able to:
1. describe the properties of limit sets;
2. define a flow and determine the limit sets of orbits in certain circumstances;
3. use the Poincare-Bendixson theorem to study the existence of limit cycles of two-dimensional systems and obtaining information about their location;
4. construct possible global phase-portraits of two-dimensional systems including those with limit cycles;
5. describe the concept of stability and use the technique of Liapunov functions to determine the stability properties of a critical point;
6. construct the phase-portrait of some three-dimensional systems.
This module is a sequel to MA31210 and develops the ideas to a more advanced level. The Poincare-Bendixson theory for two-dimensional systems is explained in detail, with emphasis on examples. Stability in the sense of Liapunov is studied and used in the investigation of three-dimensional systems.
To develop the fundamental ideas of the qualitative theory of differential equations introduced in MA31210. Particular emphasis will be placed on Poincare-Bendixson theory, Liapunov stability and the investigation of examples which arise in applications.
