带分数布朗噪声的二维Navier-斯托克斯方程

2D Navier-Stokes equation with cylindrical fractional Brownian noise

Benedetta Ferrario, Christian Olivera

摘要:

考虑二维环面上的Navier-斯托克斯方程,随机强迫项为Hurst参数为$H$的圆柱分数Wiener噪声.继[3,8]中对$1/2$情形的讨论之后,我们证明了当$7/16< H< 1/ 2$和$ 1/2<H<1$分别满足时的局部存在唯一性和全局存在唯一性.

英文摘要:

We consider the Navier-Stokes equation on the 2D torus, with a stochastic forcing term which is a cylindrical fractional Wiener noise of Hurst parameter $H$. Following [3,8] which dealt with the case $1/2$, we prove a local existence and uniqueness result when $7/16< H< 1/ 2$ and a global existence and uniqueness result when $ 1/2<H<1$.
