| contents | In this article, we investigate monotonicity of limit wave speed of periodic traveling wave solutions for a perturbed generalized KdV equation via Abelian integral. We have answered an open problem outlined by Yan et al. (2014) and the conjecture proposed by Ouyang et al. (2022). Geometric singular perturbation theory allows for the reduction of a three-dimensional dynamical system to a near-Hamiltonian planar system. Furthermore, utilizing the monotonic behavior of the ratio of Abelian integrals, we develop a method to show the existence of at most one isolated periodic traveling wave which is much simpler proof than that in Yan et al.(2014). Finally, we present numerical simulations that perfectly match the theoretical outcomes. |
