(2+1)-维色散长波方程新的精确行波解

摘要

By using the method of dynamical systems to the (2 + 1) -dimensional dispersive long wave equation , the existence of exact traveling wave solutions was proved. Under different parametric conditions, explicit exact parametric representations for the new solitary wave solutions and periodic wave solutions were obtained.%应用平面动力系统方法研究了(2+1)-维色散长波方程的精确行波解,在不同的参数条件下获得了该方程的新孤立波解和周期波解的精确的显式参数表达式.
