| Abstract: | Traveling waves of the generalized Camassa-Holm equation are studied by exploiting qualitative theory and bifurcation method of dynamical systems, the phase portraits of corresponding planar system are obtained by the key bifurcation values, and sufficient conditions guaranteeing the existence of solitary waves and kink waves are derived. It is found that the derived solitary waves and kink waves are asymmetric, which are different from the traditional symmetric solitary waves and kink waves. |

| Keywords: | generalized Camassa-Holm equation asymmetric solitary waves asymmetric kink waves existence |
