Bifurcations of Travelling Wave Solutions in Three Modified Camassa-Holm Equations
Yanggeng Fu,Jibin Li
Keywords:solitary wave solution, $M$-shape-wave solution, periodic wave solution, bifurcation, modified Camassa-Holm equation.
      This paper studies traveling wave solutions of three modified Camassa-Holm equations posed by Anco and Recio in 2019. The corresponding traveling system is a singular system of second class. The bifurcations of traveling wave solutions in the parameter space are investigated from a dynamical systems theoretical point of view. The existence of solitary wave solution, periodic wave solution and so-called $M$-shape-solution are proved.
