摘要

在本文中,我们关注三维纳维-斯托克斯方程适当弱解的可能时空奇点集的上盒计数维数。通过充分利用方程中关于Π\nabla \Pi的压力Π\Pi,我们证明该上盒维数至多为135/104(1.30)135/104(\approx1.30),这改进了Koh等人[9, J. Differential Equations, 261: 3137--3148, 2016]中的已知上盒计数维数95/63(1.51)95/63(\approx1.51)、Kukavica等人[11, Nonlinearity 25: 2775-2783, 2012]中的45/29(1.55)45/29(\approx1.55)以及Kukavica[10, Nonlinearity 22: 2889-2900, 2009]中的135/82(1.65)135/82(\approx1.65)
