摘要
该文对非线性 Schrodinger方程提出了一种新的守恒差分格式 ,并证明了该格式的收敛性与稳定性 ,通过数值计算获得如下结论 ,提出的差分格式在取适当的参数后 ,精度上好于文
In this paper, a new conservative fi nite difference scheme is proposed for nonlinear Schrdinger equation,and its convergence and stability are proved. By means of numerical computing, it is followed that the new difference scheme is better than the scheme of paper \ in precision,whensuitable parameter is adopted.
