Yanjie Zhang, Xiao Wang, Zibo Wang, Jinqiao Duan

摘要:

本文首先分析了由$α$ -稳定过程驱动的多尺度随机动力系统的投影积分方法的强收敛性和弱收敛性,该方法用于估计快分量对慢分量的影响。在此基础上,给出了投影积分法求解慢分量与用$p \in \left(1, α\right)$求解有效系统的$p$阶矩误差界。最后,我们通过一个具体的数值例子证实了我们的分析结果。

英文摘要:

In this paper, we first analyze the strong and weak convergence of projective integration methods for multiscale stochastic dynamical systems driven by $α$-stable processes, which are used to estimate the effect that the fast components have on slow ones. Then we obtain the $p$th moment error bounds between the solution of slow component produced by projective integration method and the solution of effective system with $p \in \left(1, α\right)$. Finally, we corroborate our analytical results through a specific numerical example.
