均匀磁场中MHD方程的整体适定性

Global well-posedness of the MHD equations in a homogeneous magnetic field

Dongyi Wei, Zhifei Zhang

摘要:

本文研究了具有小粘性系数和小电阻率系数的MHD方程,它们可能是不同的。这是高温等离子体中的典型设置。证明了在加权Hölder空间中,当初速度接近于0,初磁场接近于均匀磁场时,MHD方程组是整体适定的,且这种接近程度与耗散系数无关.

英文摘要:

In this paper, we study the MHD equations with small viscosity and resistivity coefficients, which may be different. This is a typical setting in high temperature plasmas. It was proved that the MHD equations are globally well-posed if the initial velocity is close to 0 and the initial magnetic field is close to a homogeneous magnetic field in the weighted Hölder space, where the closeness is independent of the dissipation coefficients.
