We show that the viscous resistive magnetohydrodynamics system with Hall effect is locally well-posed in Hs(R3)×Hs+1ε(R3) with s>12 and any small enough ε>0 such that sε>12. This space is to date the largest local well-posedness space in the class of Sobolev spaces for the system. It is also optimal according to the predominant scalings of the two equations in the system.

最佳Sobolev空间中Hall-MHD系统的局部适定性

我们表明,具有霍尔效应的粘性电阻磁流体动力学系统在局部位置良好。 Hs[R3×Hs+1个-ε[R3s>1个2个 还有足够小的 ε>0 这样 s-ε>1个2个。迄今为止,该空间是该系统Sobolev空间类别中最大的局部适定性空间。根据系统中两个方程的主要比例,它也是最佳的。
