Zdzisław Brzeźniak, Gaurav Dhariwal, Mauro Mariani

摘要:

研究了二维Navier-斯托克斯方程在解的$L^2$能量上的约束.利用不动点证明了约束Navier-斯托克斯方程在$\R^2$和$\T$上整体解的存在唯一性.我们还证明了当粘性$ν$为零时,约束Navier-Stokes方程的解收敛于欧拉方程的解。

英文摘要:

We study 2D Navier-Stokes equations with a constraint on $L^2$ energy of the solution. We prove the existence and uniqueness of a global solution for the constrained Navier-Stokes equation on $\R^2$ and $\T$, by a fixed point argument. We also show that the solution of constrained Navier-Stokes converges to the solution of Euler equation as viscosity $ν$ vanishes.
