摘要: In this paper, the Lie symmetry analysis and the generalized symmetry method are performed for a short wave model. The symmetries for this equation are given. The phase portraits of the traveling wave systems are analyzed by using the bifurcation theory of dynamical systems. The exact parametric representations of four types of traveling wave solutions are obtained.

关键词: Lie symmetry, short wave model, bifurcation method, loop solution
