Lie transformation group approach is to study the symmetry of differential equations and find an effective analytical tool. Harrison and Estabrook gives a geometric method is used to get the symmetry of differential equations , the method is the use of exterior differential forms and Lie derivatives for research . How to solve differential - difference equations symmetry in recent years has been much concern , in this paper, we will help put discrete Harrison and Estabrook exterior differential geometric methods to promote applied to 21 -dimensional Toda equations and non- Toda equations , etc. homogeneous differential - differential equations Lee symmetry analysis .
