研究了三维不可压Navier-Stokes方程适当弱解的空间二阶导数。我们表明,它是局部的任何,这改善了目前的结果。洛伦兹空间中的类似的改进也得到了更高的导数的涡光滑的解决方案。我们使用爆破技术,以获得非线性边界兼容的标度。局部研究工作的涡度方程,并使用De Giorgi迭代。在这种局部研究中,我们可以获得任何规律性的涡没有任何先验知识的压力。局部到全局的步骤使用最近构造的最大函数的输运方程。
We study the second spatial derivatives of suitable weak solutions to the incompressible Navier–Stokes equations in dimension three. We show that it is locallyfor any, which improves from the current result of. Similar improvements in Lorentz space are also obtained for higher derivatives of the vorticity for smooth solutions. We use a blow-up technique to obtain nonlinear bounds compatible with the scaling. The local study works on the vorticity equation and uses De Giorgi iteration. In this local study, we can obtain any regularity of the vorticity without any a priori knowledge of the pressure. The local-to-global step uses a recently constructed maximal function for transport equations.
