三维可压缩粘性无阻MHD系统的整体适定性

Global well-posedness for the three-dimensional full compressible viscous non-resistive MHD system

Yang Li

摘要:

本文研究了三维全可压缩粘性无阻磁流体系统。证明了强背景磁场下初边值问题解的整体适定性。它也表明,唯一的解决方案收敛到稳定状态,几乎指数率的时间趋于无穷大。该证明基于著名的两层能量方法,由Guo和Tice [ \emph{Arch. Ration. Mech. Anal.},207(2013),pp. 459- 531; \emph{Anal. PDE.},6(2013),pp. 287--369],在拉格朗日坐标中重新表述。所得结果可视为Tan和Wang [ \emph{SIAM J. Math. Anal.},50(2018),pp. 1432--1470]到导热流体的上下文。这特别验证了垂直磁场在完全可压缩无阻流体中的稳定作用。

英文摘要:

In this paper, we consider the three-dimensional full compressible viscous non-resistive MHD system. Global well-posedness is proved for an initial-boundary value problem around a strong background magnetic field. It is also shown that the unique solution converges to the steady state at an almost exponential rate as time tends to infinity. The proof is based on the celebrated two-tier energy method, due to Guo and Tice [\emph{Arch. Ration. Mech. Anal.}, 207 (2013), pp. 459--531; \emph{Anal. PDE.}, 6 (2013), pp. 287--369], reformulated in Lagrangian coordinates. The obtained result may be viewed as an extension of Tan and Wang [\emph{SIAM J. Math. Anal.}, 50 (2018), pp. 1432--1470] to the context of heat-conductive fluids. This in particular verifies the stabilization effects of vertical magnetic field in the full compressible non-resistive fluids.
