Onsager临界正则性附近粘性消失的Kato型判据

A Kato-type criterion for vanishing viscosity near the Onsager's critical regularity

Robin Ming Chen, Zhilei Liang, Dehua Wang

摘要:

考虑有界区域上三维Navier-Stokes方程斯托克斯方程弱解的粘性消失序列。在一篇开创性的论文[25]中,加藤指出,对于充分正则解,粘性极限的消失等价于在宽度与粘性成比例的边界层中粘性耗散的消失。我们证明了加藤的标准持有Hölder连续的解决方案,通过一个新的边界层叶理和全球软化的正则性指数任意接近Onsager的临界指数。

英文摘要:

We consider a vanishing viscosity sequence of weak solutions of the three-dimensional Navier--Stokes equations on a bounded domain. In a seminal paper [25] Kato showed that for sufficiently regular solutions, the vanishing viscosity limit is equivalent to having vanishing viscous dissipation in a boundary layer of width proportional to the viscosity. We prove that Kato's criterion holds for Hölder continuous solutions with the regularity index arbitrarily close to the Onsager's critical exponent through a new boundary layer foliation and a global mollification.
