具有不定常局部Lipschitz系数的快慢随机微分方程的平均原理

Averaging principle for slow-fast stochastic differential equations with time dependent locally Lipschitz coefficients

Wei Liu, Michael Röckner, Xiaobin Sun, Yingchao Xie

摘要:

研究了具有慢时标和快时标的随机微分方程的平均原理,其中漂移系数满足关于慢时标和快时标的局部利普希茨条件,慢时标方程中的系数依赖于时间$t$和$ω$ .利用时间离散和截断技术,我们证明了慢分量强收敛于相应的平均方程的解。

英文摘要:

This paper is devoted to studying the averaging principle for stochastic differential equations with slow and fast time-scales, where the drift coefficients satisfy local Lipschitz conditions with respect to the slow and fast variables, and the coefficients in the slow equation depend on time $t$ and $ω$. Making use of the techniques of time discretization and truncation, we prove that the slow component strongly converges to the solution of the corresponding averaged equation.
