论文摘要

在本文中,我们研究了二维缩放的各向异性MHD系统的全局良好性,也研究了静水压MHD,没有滑带中没有滑动边界条件,用于较小的初始数据,这是水平变量中分析性的。我们还证明MHD系统的限制(当$ε\至0 $时,其中$ε$表示初始条的高度)是由几个prandtl类似于速度的prandtl系统给出的,而初始数据很小且分析性。

In this paper, we study the global well-posedness of the two dimensional rescaled anisotropic MHD system and also to the hydrostatic MHD with no slip boundary condition in a strip, for small initial data, which are analytic in the horizontal variable. We also justify the limit of the MHD system (when $ε\to 0$ where $ε$ denotes the height of the initial strip) is given by a couple of a Prandtl like system for the velocity and a magnetic field equation when the initial data are small and analytic.
