摘要

在本文中,设 S\mathcal{S} 表示三维Navier-Stokes方程适定弱解的可能内部奇异集。我们将该集合的已知上盒计数维数从[24]中的 360/277(1.300)360/277(\approx1.300) 改进到 975/758(1.286)975/758(\approx1.286)。此外,还证明了 Λ(S,r(log(e/r))σ)=0(0σ<27/113)\Lambda(\mathcal{S},r(\log(e/r))^{\sigma})=0(0\leq\sigma<27/113),这扩展了Choe和Lewis [3, J. Funct. Anal., 175: 348-369, 2000]以及Choe和Yang等人 [4, Comm. Math. Phys, 336: 171-198, 2015]此前关于通过对数因子改进经典Caffarelli-Kohn-Nirenberg定理的相关结果。该证明受Guevara和Phuc在[7, Calc. Var. 56:68, 2017]中证明的新 ε\varepsilon-正则性准则的启发。
