旋转斑块模型的平凡解

On the trivial solutions for the rotating patch model

Taoufik Hmidi

摘要:

本文研究了欧拉方程顺时针单连通旋转曲面。利用移动平面方法证明了在{ \it slightly}凸区域类中Rankine涡是该问题的唯一解。在第二部分中,我们讨论了角速度为$Ω=\frac12$的情况,并且在没有任何几何条件的情况下,我们证明了V-态的集合是平凡的,并且简化为Rankine涡旋。

英文摘要:

In this paper we study the clockwise simply connected rotating patches for Euler equations. By using the moving plane method we prove that Rankine vortices are the only solutions to this problem in the class of {\it slightly} convex domains. We discuss in the second part of the paper the case where the angular velocity $Ω=\frac12$ and we show without any geometric condition that the set of the V-states is trivial and reduced to the Rankine vortices.
