| Abstract: | Lie algorithm combined with differential form Wu's method is used to complete the symmetry classification of partial differential equations(PDEs) containing arbitrary parameter. This process can be reduced to solve a large system of determining equations, which seems rather difficult to solve, then the differential form Wu's method is used to decompose the determining equations into a series of equations, which are easy to solve. To illustrate the usefulness of this method, we apply it to some test problems, and the results show the performance of the present work. |
