Abstract

. In this paper, we aim to establish a strong averaging principle for stochastic tidal dynamics equations. The averaging principle is an effective method for studying the qualitative analysis of nonlinear dynamical systems. Under suitable assumptions, utilizing Khasminkii’s time discretization approach, we derive a strong averaging principle showing that the solution of stochastic tidal dynamics equations can be approximated by solutions of the system of averaged stochastic equations in the sense of convergence in mean square.

随机潮汐动力学方程的平均原理
。本文旨在建立随机潮汐动力学方程的强平均原理。平均原理是研究非线性动力系统定性分析的一种有效方法。在适当的假设条件下,利用Khasminkii的时间离散化方法,导出了一个强平均原理,表明随机潮汐动力学方程的解可以用平均随机方程组的解在均方收敛意义上逼近。
