大初值下三维Navier-斯托克斯方程的整体适定性

On the global wellposedness of the 3-D Navier-Stokes equations with large initial data

Jean-Yves Chemin, Isabelle Gallagher

摘要:

本文给出了周期三维不可压Navier-斯托克斯方程整体适定的一个条件。该条件不是初始数据的小性条件,因为在尺度不变空间$ B^{-1}\_{\infty,\infty}$中允许数据任意大,该尺度不变空间包含所有已知空间,其中存在小数据的全局解。的小条件是一个非线性类型的条件,而对初始数据,这样的初始数据的一个明确的例子构造,这是任意大,但产生一个全球性的,光滑的解决方案。

英文摘要:

We give a condition for the periodic, three dimensional, incompressible Navier-Stokes equations to be globally wellposed. This condition is not a smallness condition on the initial data, as the data is allowed to be arbitrarily large in the scale invariant space $ B^{-1}\_{\infty,\infty}$, which contains all the known spaces in which there is a global solution for small data. The smallness condition is rather a nonlinear type condition on the initial data; an explicit example of such initial data is constructed, which is arbitrarily large and yet gives rise to a global, smooth solution.
