二维Navier-Stokes运动周期解的稳定性

Stability of two-dimensional Navier-Stokes motions in the periodic case

Wojciech Zajączkowski, Ewa Zadrzyńska

摘要:

本文考虑了在具有周期边界条件的盒子中由斯托克斯方程描述的运动.首先证明了整体强二维解的存在性。接下来,我们证明了存在的整体强三维解的假设下,初始数据和外力是足够接近的初始数据和外力的二维问题在适当的空间。第二个结果可视为强二维解在适当强三维运动集合中的稳定性。

英文摘要:

We consider the motion described by the Navier-Stokes equations in a box with periodic boundary conditions. First we prove the existence of global strong two-dimensional solutions. Next we show the existence of global strong three-dimensional solutions under the assumption that the initial data and the external force are sufficiently close to the initial data and the external force of the two-dimensional problem in appropriate spaces. The second result can be treated as stability of strong two-dimensional solutions in the set of suitably strong three-dimensional motions.
