随机动力系统不变叶理的逼近

Approximation of invariant foliations for stochastic dynamical systems

Xu Sun, Xingye Kan, Jinqiao Duan

摘要:

不变叶理是描述和理解非线性动力系统定性行为的几何结构。然而,对于随机动力系统,这些几何结构本身就是复杂的随机集合。因此,它是可取的,有一些技术来近似随机不变叶理。本文通过渐近分析,对具有小噪声扰动的动力系统的不变叶理进行了近似。即,随机不变叶理表示为确定性不变叶理的扰动,估计偏差误差。

英文摘要:

Invariant foliations are geometric structures for describing and understanding the qualitative behaviors of nonlinear dynamical systems. For stochastic dynamical systems, however, these geometric structures themselves are complicated random sets. Thus it is desirable to have some techniques to approximate random invariant foliations. In this paper, invariant foliations are approximated for dynamical systems with small noisy perturbations, via asymptotic analysis. Namely, random invariant foliations are represented as a perturbation of the deterministic invariant foliations, with deviation errors estimated.
