摘要

本文建立了反射随机演化方程的平均原理。为此，我们首先构建了与原方程相对应的平均方程，然后利用时间离散化方法证明，当参数归零时，原方程在概率上收敛于相应的平均方程。我们的模型以随机纳维-斯托克斯方程为例。

Averaging principle for reflected stochastic evolution equations

An averaging principle for reflected stochastic evolution equations is established in this paper. To this end, we firstly construct the averaged equations corresponding to the original equations and then demonstrate, by utilizing the time discretization method, that the original equations converge to the corresponding averaged equations in probability, as the parameter goes to zero. Our model includes stochastic Navier–Stokes equations as a special example.
