split-step methodMulti-symplectic methods have recently been considered as a generalization of symplectic ODE methods to the case of Hamiltonian PDEs. The symplectic of Hamiltonian systems is well known, but for

However, simulations show that the method can become unstable on the background of a soliton. We present an analysis explaining this instability. Both this analysis and the instability itself are substantially different from those of the Fourier split-step method, which computes the spatial ...

In this paper, we construct a new split-step method for solving stochastic differential equations, namely the split-step θ-method. Under Lipschitz and linear growth conditions, we establish a mean-square convergence theory of split-step θ-approximate solutions. Moreover, the mean-square stability...
【摘要】给出随机微分方程的split-step欧拉格式的算法,并证明了当方程的偏移系数和扩散系数均满足线性增长条件和李普希兹条件的情况下,此方法用以求解随机微分方程的收敛性,并且求出强收敛的阶是1/2.同时证明了split-step近似解的均方收敛理论. 【期刊名称】《烟台大学学报(自然科学与工程版)》 【年(卷),期】2014...

As the explicit method and the semi-implicit method, Wang [14] have considered the three-stage stochastic Runge–Kutta methods for Stratonovich SDEs. As implicit methods, Wang and Liu [15] presented the split-step backward balanced Milstein methods for stiff Itô stochastic systems. In this pa...
Molecular cloning was performed inE. coliTOP10 cells using the ClonExpress Ultra One Step Cloning Kit (Vazyme Biotech) unless otherwise specified. To monitor the human cell transfection efficiency, a reporter gene encoding the red fluorescent protein mScarlet was cloned downstream of the CMV promoter,...
2) the Split-step Fourier Method 分步Fourier方法 1. Numerically simulate NLS equation through using the Split-step Fourier Method and ask out the center displacement of 1-soliton. 使用分步Fourier方法对NLS方程做数值模拟,求出1-孤子中心的位移,通过与1-孤子中心位移的解析解做比较,验证了解析解,也...
