摘要 为了研究一类广义Camassa-Holm方程的行波解问题,通过行波变换及平面非线性动力系统的分岔理论,借助Maple符号计算软件程序,研究了一类广义Camassa-Holm方程的分岔特性,给出了该系统在不同分支参数空间中的相图构型. In order to conduct research on traveling wave solutions of a generalized Camassa-Holm equation,a bifurcations of a generalized Camassa-Holm equation is considered in this paper by using the transformation of traveling wave,bifurcation theory of planar dynamical system and the Maple symbolic computation program.Different phase portraits of the system in different regions are obtained.
