Symmetries of Discrete Systems

Abstract

In this series of lectures presented at the CIMPA Winter School on Discrete Integrable Systems in Pondicherry, India, in February, 2003 we give a review of the application of Lie point symmetries, and their generalizations to the study of difference equations. The overall theme of these lectures could be called "continuous symmetries of discrete equations".Comment: 58 pages, 5 figures, Lectures presented at the Winter School on Discrete Integrable Systems in Pondicherry, India, February 200
