AI总结:

本文提出了一种适用于压缩纳维-斯托克斯方程的申比罗特型准则,通过新的弱型交换子估计,实现了弱解的能量守恒条件,且比先前工作更弱。

摘要:

我们证明了压缩纳维-斯托克斯方程的弱解在申比罗特型正则性准则下满足能量等式。我们的方法适用于具有常数和退化粘性系数的流体,并依赖于一种新的弱型交换子估计。这些准则严格弱于先前工作中[Arch. Ration. Mech. Anal., 225 (2017)]和[SIAM J. Math. Anal. 52 (2020)]所要求的准则。

英文摘要:

We prove that weak solutions to the compressible Navier-Stokes equations satisfy the energy equality under a Shinbrot-type regularity criterion. Our method applies to the fluids with both constant and degenerate viscosity and relies on a novel weak-type commutator estimate. These criterion are strictly weaker than those required in prior works [Arch. Ration. Mech. Anal., 225 (2017)] and [SIAM J. Math. Anal. 52 (2020)].
