摘要: 由Hirota方法推导出混合AKNS-CLL方程的双线性导数方程和N-孤子解, 并比较混合AKNS-CLL方程、AKNS方程和CLL方程的单孤子解|q|和|r|的图像, 可以发现混合AKNS-CLL方程的特征形状不同于经典AKNS和CLL方程解. 最后, 通过约化, 得到混合非线性Schrödinger方程的N-孤子解.

关键词: N-孤子解, Hirota方法, 混合AKNS-CLL方程, 混合非线性Schr¨odinger方程

Abstract: The bilinear form and N-soliton solutions are derived for a combined AKNSCLL equation using the Hirota approach. These solutions are novel in general. The one-soliton solutions of the combined AKNS-CLL equation, AKNS equation and CLL equation were drawn. Also, the combined AKNS-CLL equation is given a different characteristic from the classical AKNS and CLL equations. The bilinear form and N-soliton solutions of combined nonlinear Schr¨odinger equation are obtained by reduction.

Key words: N-soliton solutions, combined AKNS-CLL equation, combined nonlinear Schr¨odinger equation, Hirota approach
