三维Navier-斯托克斯方程解能量相等的几何条件

A geometric condition implying energy equality for solutions of 3D Navier-Stokes equation

Roman Shvydkoy

摘要:

证明了三维Navier-斯托克斯方程的弱解$u$(属于$L^3L^{9/2}$类)和$\n u$(属于$L^3L^{9/5}$类)在时间上远离1/2-Hölder连续曲线的局部满足广义能量等式.特别地,每种这样的解决方案都是合适的。

英文摘要:

We prove that every weak solution $u$ to the 3D Navier-Stokes equation that belongs to the class $L^3L^{9/2}$ and $\n u$ belongs to $L^3L^{9/5}$ localy away from a 1/2-Hölder continuous curve in time satisfies the generalized energy equality. In particular every such solution is suitable.
