摘要
研究在量子场理论、弱非线性色散水波、非线性光学等领域中出现的Gerdjikov-Ivanov方程.对Gerdjikov-Ivanov方程的研究会导出具有高次非线性项的非线性数学物理方程.选取Liénard方程作为辅助常微分方程,借助于它并根据齐次平衡原则,求解了Gerdjikov-Ivanov方程,得到了该方程的包络孤立波解和包络正弦波解.
The C, erdjikov-Ivanov equation which appears, in the fields of quanta field theory, weak nonlinear dispersive water wave, nonlinear optics, etc., has been discussed. Nonlinear mathematical physics equation with higher order nonlinear terms is educed in the discussion of Gerdjikov-Ivanov equation. The Lienard equation is chosen as subsidiary ordinary differential equation, with the help of which and according to homogeneous balance principle, the Gerdjikov-Ivanov equation has been solved, and the envelope solitary wave solutions and envelope sinusoidal wave solutions have been obtained.
