三维轴对称小涡Navier-Stokes方程组的整体适定性

On the global well-posedness of 3-D axi-symmetric Navier-Stokes system with small swirl component

Yanlin Liu, Ping Zhang

摘要:

本文证明了临界Lebesgue空间中三维轴对称Navier-Stokes方程组的局部适定性。在小的初始数据下,我们也得到了整体的适定性结果。此外,在几乎临界空间中,当速度的初始涡旋分量足够小时,我们仍然可以证明系统的全局适定性。

英文摘要:

In this paper, we prove the local well-posedness of 3-D axi-symmetric Navier-Stokes system with initial data in the critical Lebesgue spaces. We also obtain the global well-posedness result with small initial data. Furthermore, with the initial swirl component of the velocity being sufficiently small in the almost critical spaces, we can still prove the global well-posedness of the system.
