关于3D Navier-Stokes方程渐近轴对称解的解析力研究
Regularity of asymptotically axisymmetric solutions to the 3D Navier-Stokes equations with analytic forcing
这是关于流体力学中一个经典问题的数学证明,对研究3D Navier-Stokes方程的学者可能有参考价值。
本文研究了3D Navier-Stokes方程在解析力作用下的渐近轴对称解的正规性。作者假设解满足特定类型II各向异性角平均约束和轴对称性,证明了这些解在潜在奇点处是正规的。
这意味着在OpenAI的构造中,以及任何具有类似性质且力在C2空间变量上保持有界的构造中,力在奇点附近既不能恒为零,也不能局部一致地解析。
Regularity of asymptotically axisymmetric solutions to the 3D Navier-Stokes equations with analytic forcing
OpenAI~\cite{OpenAIManuscript} has recently announced a proof of finite time singularity formation for the 3D Navier-Stokes equations, in the presence of a $C^\infty$-smooth body force. The construction in~\cite{OpenAIManuscript} has a few key features, among which we single out: (i) the angular mean of the solution satisfies specific Type II bounds which are anisotropic; (ii) the solution is exactly axisymmetric in a collapsing core region. In this paper we consider solutions of the 3D Navier-Stokes equations in the presence of a real-analytic body force, and assume that these solutions satisfy properties (i) and (ii) above. We prove that such solutions are in fact regular at the putative singular point. As a consequence, in the construction of~\cite{OpenAIManuscript}, and in any construction with properties (i) and (ii) whose force remains bounded in $C^2$ up to the singular time, the force can neither vanish identically near the singular point, nor be real analytic in the space variables, locally uniformly in time. The main idea of the proof is inspired by our earlier work~\cite{CIV26} and the companion paper~\cite{CIVEulerLength}: zooming-in at the putative singularity using the anisotropic length scales provided by the a priori bounds, we arrive at ancient limits whose PDE evolution imposes additional rigidity.
