三维Navier-斯托克斯方程一类大初值问题的整体适定性

Global wellposedness for a certain class of large initial data for the 3D Navier-Stokes Equations

Percy Wong

摘要:

本文考虑了环面上三维Navier-斯托克斯方程的一类特殊的初值问题,其中初值分量具有一定的正交性。我们证明了,在这样的条件下,Navier-斯托克斯方程是整体适定的。我们还表明,在满足我们考虑的条件的临界规范$B^{-1}_{\infty,\infty}$的意义上,存在大量初始数据。

英文摘要:

In this article, we consider a special class of initial data to the 3D Navier-Stokes equations on the torus, in which there is a certain degree of orthogonality in the components of the initial data. We showed that, under such conditions, the Navier-Stokes equations are globally wellposed. We also showed that there exists large initial data, in the sense of the critical norm $B^{-1}_{\infty,\infty}$ that satisfies the conditions that we considered.
