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