Description:  Aims: To provide an accessible but rigorous treatment of initialvalue problems for nonlinear systems of ordinary differential equations, including existence and uniqueness of maximal solutions and Lyapunov stability theory, illustrated by examples. Foundations will be laid for advanced studies in dynamical systems, mechanics and control. The material is also useful in mathematical biology and numerical analysis. Learning Outcomes: After taking this unit, students should be able to: * Demonstrate understanding of and prove basic results in the theory of ordinary differential equations including: existence and uniqueness for the initialvalue problem, basic properties of flows and limit sets, Lyapunov's stability theorem and LaSalle's invariance principle. * Apply the theory to analyse the behaviour of simple examples. Skills: Numeracy T/F, A Problem Solving T/F, A Written Communication F (on problem sheets) Content: General definition of an ODE. Examples from diverse areas. Elementary methods: separation of variables, variation of constant, estimates using Gronwall's lemma. Existence and uniqueness for maximal solutions for ODEs with sufficiently regular coefficients (via contraction mapping theorem), continuous dependence on initial conditions. Autonomous ODEs: introduction to local and global flows, orbits, limit sets, integral invariance principle, stability, Lyapunov functions, Lyapunov stability theorem, LaSalle's invariance principle, application to examples.
