连续半鞅驱动的随机微分方程Milstein格式的渐近误差

Asymptotic error for the Milstein scheme for SDEs driven by continuous semimartingales

Liqing Yan

摘要:

提出了一种Milstein型格式,以提高其逼近连续半鞅向量驱动的随机微分方程解收敛速率.在有限变差部分的附加假设下,给出了当向量为连续局部鞅或连续半鞅时,该速率为$1/n$的一个充要条件.研究了归一化误差过程的渐近性态(弱收敛性)。

英文摘要:

A Milstein-type scheme was proposed to improve the rate of convergence of its approximation of the solution to a stochastic differential equation driven by a vector of continuous semimartingales. A necessary and sufficient condition was provided for this rate to be $1/n$ when the SDE is driven by a vector of continuous local martingales, or continuous semimartingales under an additional assumption on their finite variation part. The asymptotic behavior (weak convergence) of the normalized error processes was also studied.
