随机和随机偏微分方程的不变流形

Invariant manifolds for random and stochastic partial differential equations

Tomas Caraballo, Jinqiao Duan, Kening Lu, Bjorn Schmalfuss

摘要:

随机不变流形是理解随机影响下的复杂动力学的有用几何对象。在非一致双曲性或非一致指数二分性条件下,证明了一类\emph{random}偏微分方程和\emph{stochastic}偏微分方程的随机伪稳定和伪非稳定流形的存在性.与随机\emph{ordinary}微分方程的不变流形理论不同,不使用随机范数。然后将所得结果应用于带线性乘性噪声的非线性随机偏微分方程。

英文摘要:

Random invariant manifolds are geometric objects useful for understanding complex dynamics under stochastic influences. Under a nonuniform hyperbolicity or a nonuniform exponential dichotomy condition, the existence of random pseudo-stable and pseudo-unstable manifolds for a class of \emph{random} partial differential equations and \emph{stochastic} partial differential equations is shown. Unlike the invariant manifold theory for stochastic \emph{ordinary} differential equations, random norms are not used. The result is then applied to a nonlinear stochastic partial differential equation with linear multiplicative noise.
