摘要

摘要: 对于某些非线性波方程,动力系统方法的分析说明所谓的圈孤子解和反圈孤子解实际上是人为的现象．所谓的圈孤子解由3个解合成,不是1个真解．是否存在非线性波方程,使得该方程的行波系统存在真正的1个圈解? 若这样的解存在,它们有怎样的精确参数表示?该文回答这些问题．

Abstract: Dynamical analysis revealed that for some nonlinear wave equations, loop-and inverted loop-soliton solutions are merely visual artifacts. So called loop-soliton solution consists of three solutions which is not one real solution. Whether or not there exist some nonlinear wave equations for which there exists a/real0 loop-solution? If yes, what are their precise parametric representations of these loop traveling wave solutions? These problems are answered.
- breaking wave solution /
- loop-solution /
- no nlinear wave equation /
- planar dynamical system
