摘要
本文研究一类立方非线性Schrdinger方程的对称约化和精确解问题。首先,利用直接对称方法,得到非线性Schrdinger方程的对称;其次,根据求解相应的特征方程获得非线性Schrdinger方程的相似约化;最后,结合辅助方程获得非线性Schrdinger方程的精确解。这些解包括孤立波解、Jacobi椭圆函数解以及三角函数解。
Symmetry of nonlinear Schrdinger equation was investigated. Applying direct symmetry method,symmetry of nonlinear Schrdinger equation was derived. By solving corresponding characteristic equation associated with the symmetry equation,symmetry reduction of nonlinear Schrdinger were obtained based on a fourth- order auxiliary equation,these solutions include solitary wave solutions,Jacobi elliptic function solutions and trigonometric function solutions.
