balanced methodIn this paper, a new Milstein-type derivative-free numerical method is proposed for It stochastic differential equations (SDEs). The mean-square stability of the method is thoroughly analyzed, and its error estimation is rigorously examined. The method is subsequently extended twice ...
We consider the implementation of the split-step method where the linear part of the nonlinear Schr"odinger equation is solved using a finite-difference discretization of the spatial derivative. The von Neumann analysis predicts that this method is unconditionally stable on the background of a ...

The proposed method is based on a split-step method which decomposes the original equation into two parts, a linear problem and a nonlinear problem. In order to demonstrate the high accuracy and capability of the newly proposed method, a simple problem of periodic waves is presented to compare...
