题目:Solitary wave solutions of the perturbed mKdV equation
报告人:张丽俊 教授(山东科技大学)
摘要:The solitary wave solutions of a perturbed mKdV equation is investigated by using the singular perturbation method and Melnikov's method. The two families of solitary wave solutions of the unperturbed system, having arbitrary positive wave speed and approaching a given value as time tends to infinity, persist for two specific wave speeds respectively. A new type of solitary wave solutions possessing both valley and peak with a particular wave speed appear after small perturbation, which exhibits the rich dynamical properties of the perturbed nonlinear wave equations.
