| Abstract: | For Burgers-KdV travelling wave equation,which satisfies secons nonlinear order ordinary differntial equation,We will apply the classical Lie group theory to show that the corresponding travelling wave equation admits a double parameter Lie group if and only if parameter is satisfied in particular case.Under this condition,based on a method different to the traditional one,its two independent first integrals are given. |
| Keywords: | Burgers-KdV travelling wave equation Lie group first integral |
