摘要:

使用Heun法求解系数间断的随机微分方程, 给出了数值计算格式, 并讨论了格式的弱收敛性. 数值实验表明, 与Euler法相比, Heun法求解系数间断的随机微分方程收敛速度更快.

关键词: Heun法, 系数间断, 随机微分方程, 弱收敛

Abstract:

We studied the numerical method for stochastic differential equations with discontinuous coefficients via Heun method. The numerical computational scheme was given to solve such a type of equations. The weak convergence of the method was also discussed. The numerical examples demonstrate that the convergence rate of Heun method was faster than that of Euler method.

Key words: Heun method, discontinuous coefficient, stochastic differential equation, weak convergence
