关于具有奇异性的完全可积方程的孤立波及其性质,人们似乎知之甚少。利用动力系统的分支方法研究了一类可积方程的孤立波解。我们强调两个有趣的结果孤立波。首先,对于任意的波速,在可积方程中确实存在无穷多个孤立波,这些孤立波根据它们的表达式和运动形式进行了分类。第二,我们发现一族孤立波,其轮廓看起来像树桩。
Little seems to be known about the solitary waves and their properties of the completely integrable equations with singularity. This paper addresses the solitary waves of an integrable equation based on the bifurcation method of dynamical systems. We highlight two interesting results on the solitary waves. First, for arbitrary wave speed, there do exist infinitely many solitary waves in the integrable equation, which are classified by their expressions and forms of motion. Second, we find a family of solitary waves whose profiles seem like tree stumps.
