摘要
利用动力系统分岔方法和微分方程数值模拟的方法研究了(2+1)维Zoomeron方程,获得了系统的参数分岔集和不同拓扑结构的相图.根据这些相图确定了系统的无界行波,并通过计算复杂的椭圆积分获得了它们的解析表达式.
In this paper,the bifurcation method of dynamical system and numerical simulation method of differential equation are employed to investigate the （2＋1）-dimensional Zoomeron equation.We obtain differently qualitative phase portraits,by which all traveling waves are identified.Furthermore,by calculating some complicated integrals,we obtain the exact expressions of these unbounded traveling waves.
