具有水平耗散和水平磁扩散的二维MHD方程的整体正则性

Global regularity for the 2D MHD equations with horizontal dissipation and horizontal magnetic diffusion

Marius Paicu, Ning Zhu

摘要:

本文在适当的小初值条件下,建立了条形区域$\mathbb{T}\times\mathbb{R}$中仅含水平耗散和水平磁扩散的二维MHD系统经典解的整体正则性。为了证明这一点,我们结合Littlewood-Paley分解与各向异性不等式,建立一个关键的交换子估计。我们还分析了解的渐近性态。此外,还得到了具有水平耗散的二维简化热带气候模式的整体经典解的存在唯一性。

英文摘要:

This paper establishes the global regularity of classical solution to the 2D MHD system with only horizontal dissipation and horizontal magnetic diffusion in a strip domain $\mathbb{T}\times\mathbb{R}$ when the initial data is suitable small. To prove this, we combine the Littlewood-Paley decomposition with anisotropic inequalities to establish a crucial commutator estimate. We also analysis the asymptotic behavior of the solution. In addition, the global existence and uniqueness of classical solution is obtained for the 2D simplified tropical climate model with only horizontal dissipations.
