三维Navier-Stokes方程组的局部能量界和$ε$正则性准则

Local energy bounds and $ε$-regularity criteria for the 3D Navier-Stokes system

Cristi Guevara, Nguyen Cong Phuc

摘要:

考虑三维Navier-斯托克斯方程系统。我们得到了一些新的局部能量界,使我们能够改进几个$ε$ -正则性准则。这里的关键思想是把“水头压力”看作是属于某个负阶分数索伯列夫空间的有符号分布。这使我们能够在我们的标准中捕获压力的振荡。

英文摘要:

The system of three dimensional Navier-Stokes equations is considered. We obtain some new local energy bounds that enable us to improve several $ε$-regularity criteria. They key idea here is to view the `head pressure' as a signed distribution belonging to certain fractional Sobolev space of negative order. This allows us to capture the oscillation of the pressure in our criteria.
