Strang splitting structure-preserving high-order compact difference schemes for nonlinear convection diffusion equations

Autor: Kuang, Baolin, Xie, Shusen, Fu, Hongfei

In this paper, we present a class of high-order and efficient compact difference schemes for nonlinear convection diffusion equations, which can preserve both bounds and mass. For the one-dimensional problem, we first introduce a high-order compact S

Strang Splitting for Parametric Inference in Second-order Stochastic Differential Equations

Autor: Pilipovic, Predrag, Samson, Adeline, Ditlevsen, Susanne

We address parameter estimation in second-order stochastic differential equations (SDEs), prevalent in physics, biology, and ecology. Second-order SDE is converted to a first-order system by introducing an auxiliary velocity variable raising two main

Nonadiabatic conical intersection dynamics in the local diabatic representation with Strang splitting and Fourier basis

Autor: Gu, Bing

We develop and implement an exact conical intersection nonadiabatic wave packet dynamics method that combines the local diabatic representation, Strang splitting for the total molecular propagator, and discrete variable representation with uniform gr
