We assume that Ω is either the whole space or a half-space or a smooth bounded or exterior domain in , and is a suitable weak solution of the MHD equations in . We show that is a regular point of the solution if the limit inferior (for ) of the sum of the –norms of u and b over an arbitrarily small ball is less than infinity.

我们假设Ω是整个空间 或位于 , 和 是MHD方程的适当弱解 。我们证明 是解决方案的常规点 如果极限低于 )的总和 –在任意小的球上的u和b的范数 小于无穷大。
