摘要

摘要本文考虑了具有库德里亚肖夫折射率定律的非线性薛定谔方程。通过使用动力系统方法，我们得到了行波系统在不同参数条件下的相位肖像分岔。对应于一些特殊的水平曲线，我们推导出了不同参数条件下可能的精确显式参数表示解（包括峰子、周期峰子、孤波解和紧凑子）。

Peakon, Periodic Peakons, Compactons and Bifurcations of nonlinear Schrödinger’s Equation with Kudryashov’s Law of Refractive Index

Abstract

In this paper, we consider the nonlinear Schrödinger’s equation with Kudryashov’s law of refractive index. By using the method of dynamical systems, we obtain bifurcations of the phase portraits of the traveling wave system under different parameter conditions. Corresponding to some special level curves, we derive possible exact explicit parametric representations of solutions (including peakon, periodic peakon, solitary wave solutions and compactons) under different parameter conditions.
