| 英文摘要 | Based upon Cartan's geometric formulation of differential equations, Harrison and Estabrook proposed a geometric approach for the symmetries of differential equations. In this Letter, we extend Harrison and Estabrook's approach to analyze the symmetries of differential-difference equations. The discrete exterior differential technique is applied in our approach. The Lie symmetry of (2 + 1)-dimensional Toda equation is investigated by means of our approach. (C) 2008 Elsevier B.V. All rights reserved. |
