Aims
- To provide an introduction to modern analytical methods for nonlinear ordinary differential equations in real variables.
Content
- Smooth ODEs: existence and uniqueness of solutions.
- Autonomous ODEs: orbits, equilibrium and periodic solutions.
- Linearisation: Hartman-Grobman, stable-manifold theorems, phase portraits for non-linear systems, stability of equilibrium.
- Flow, Fixed points: Brouwer's Theorem, periodic solutions, Poincare-Bendixson and related theorems, orbital stability.
- Hopf and other local bifurcations from equilibrium, bifurcations from periodic solutions.
Learning Outcomes
Subject-specific Knowledge:
- By the end of the module students will: be able to solve novel and/or complex problems in Dynamical Systems.
- have a systematic and coherent understanding of theoretical mathematics in the field of Dynamical Systems.
- have acquired a coherent body of knowledge of these subjects demonstrated through one or more of the following topic areas: (mostly second-order) non-linear ODE's applied to the following:
- a smooth finite dimensional dynamical system as a direction field on a manifold.
- critical points and cycles as attractors, and their interaction via local bifurcations of co-dimension one.
- Local linearization, Lyapunov functions, the Poincare and Bendixson theorems of plane topology, and the Hopf bifurcation theorem.
Subject-specific Skills:
- In addition students will have specialised mathematical skills in the following areas which can be used with minimal guidance: Modelling.
Key Skills:
Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module
- Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
- Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
- Formatively assessed assignments provide practice in the application of logic and high level of rigour as well as feedback for the students and the lecturer on students' progress.
- The end-of-year examination assesses the knowledge acquired and the ability to solve predictable and unpredictable problems.
