关于二维磁流体力学-α系统的一点注记
A remark on the two-dimensional magneto-hydrodynamics-alpha system
摘要:
研究了具有分数阶拉普拉斯算子的二维广义磁流体力学- $α$系统的耗散项和扩散项。我们表明,速度和磁场的解决方案对保持其初始的正则性在所有情况下,当功率加起来为1。这解决了一般情况下的全局正则性问题,作者在[33]中指出这是一个问题。
英文摘要:
We study the two-dimensional generalized magnetohydrodynamics-$α$ system with fractional Laplacians in the dissipative and diffusive terms. We show that the solution pair of velocity and magnetic fields preserves their initial regularity in all cases when the powers add up to one. This settles the global regularity issue in the general case which was remarked by the authors in [33] to be a problem.
