Many texts teach solution methods for differential equations, but this is the first that explains how to extend these methods to difference equations. It assumes no prior knowledge of difference equations, making it ideal for newcomers, but also contains much new material that will interest researchers in the field.

This book is a straightforward introduction to symmetry methods, and is aimed at applied mathematicians, physicists, and engineers. The presentation is informal, using many worked examples to illustrate the main symmetry methods. It is designed to enable postgraduates and advanced undergraduates to master the main techniques quickly and easily.
