具有大垂向粘性系数的三维各向异性Navier-Stokes方程组的整体适定性

Global well-posedness of 3-D anisotropic Navier-Stokes system with large vertical viscous coefficient

Yanlin Liu, Ping Zhang

摘要:

本文首先证明了三维各向异性Navier-Stokes方程组的整体适定性,条件是方程组的垂向粘性系数足够大.然后我们将构造一族初始数据,$u_{0,ν},$,它们在垂直变量上变化足够快,并且在空间上不小,$BMO^{-1}.$。然而,如果$ν$足够大,则$u_{0,ν}$产生经典3-D Navier-Stokes系统的唯一整体解。

英文摘要:

In this paper, we first prove the global well-posedness of 3-D anisotropic Navier-Stokes system provided that the vertical viscous coefficient of the system is sufficiently large compared to some critical norm of the initial data. Then we shall construct a family of initial data, $u_{0,ν},$ which vary fast enough in the vertical variable and which are not small in the space, $BMO^{-1}.$ Yet $u_{0,ν}$ generates a unique global solution to the classical 3-D Navier-Stokes system provided that $ν$ is sufficiently large.
