三维斯托克斯方程的一个方向导数的Prodi-Serrin条件

Prodi--Serrin condition for 3D Navier--Stokes equations via one directional derivative of velocity

Chen Hui, Le Wenjun, Qian Chenyin

摘要:

本文考虑三维Navier-斯托克斯方程弱解的条件正则性。更精确地说,我们证明了,如果一个方向导数的速度,说$\partial_3 u,$满足$\partial_3 u \in L^{p_0,1}(0,T; L^{q_0}(\mathbb{R}^3))$与$\frac{2}{p_{0}}+\frac{3}{q_{0}}=2$和$\frac{3}{2}<q_0< +\infty,$,那么弱解是正规的$(0,T].$的证明是基于新的局部能量估计介绍的Chae-Wolf(arXiv:1911.02699)和Wang-Wu-Zhang(arXiv:2005.11906)。

英文摘要:

In this paper, we consider the conditional regularity of weak solution to the 3D Navier--Stokes equations. More precisely, we prove that if one directional derivative of velocity, say $\partial_3 u,$ satisfies $\partial_3 u \in L^{p_0,1}(0,T; L^{q_0}(\mathbb{R}^3))$ with $\frac{2}{p_{0}}+\frac{3}{q_{0}}=2$ and $\frac{3}{2}<q_0< +\infty,$ then the weak solution is regular on $(0,T].$ The proof is based on the new local energy estimates introduced by Chae-Wolf (arXiv:1911.02699) and Wang-Wu-Zhang (arXiv:2005.11906).
