Module Description

The course provides an overview of standard methods for the solution of single ordinary differential equations and systems of equations, with an introduction to some of the underlying theory.


Definitions. First-order differential equations:

linear, separable.

Second-order differential equations.

reduction of order, constant coefficients;

second-order linear equations: ordinary points and regular singular points.

Euler's equation.

Series solutions of second-order linear differential equations.

Power series, solutions about an ordinary point.

Solutions about a regular singular point.

Equal roots of indicial equation and roots differing by an integer.

Introduction to systems of first-order equations.

Two linear first-order equations.

Non-linear differential equations and stability.

Autonomous systems: trajectories in the phase plane, critical points.

Stability and asymptotic stability.

Linear and almost linear systems; classification of critical points.

Competing species and predator-prey problems.

On completion of the course students should be able to:

- use some of the standard methods for solution of first- and second-order ordinary differential equations;

- be aware of the implications of existence and uniqueness theorems;

- solve systems of linear first-order equations in two unknowns with constant coefficients;

- analyse the stability characteristics of non-linear systems in two unknowns.
