摘要
主要利用直接截断法来讨论非线性薛定谔微分方程:iut+uxx+α0|u|2u+i[γ1uxxx+γ2|u|2ux+γ3(|u|2)xu]=0(1)的精确解。借助于符号计算软件Maple,得到了此方程一些新的含Jacobi椭圆函数的精确解。
Using the direct truncation method, some new exact solutions including Jacobi elliptic function of the higher order nonlinear Schrodinger equation:
iu1+uxx+α0|u|^2u+i[γ1uxx+γ2|u|^2ux+γ3(|u|^2)xu]=0
were solved with the help of Maple soft of symbol computation.
