理想可压缩MHD方程熵守恒解的非唯一性

Non-uniqueness of entropy-conserving solutions to the ideal compressible MHD equations

Christian Klingenberg, Simon Markfelder

摘要:

本文研究了二维理想可压缩磁流体动力学(MHD)方程。我们表明,存在特定的初始数据,其中一个获得无穷多个熵守恒弱解使用凸积分技术。我们的结果对于等熵情况也是正确的。

英文摘要:

In this note we consider the ideal compressible magneto-hydrodynamics (MHD) equations in a special two dimensional setting. We show that there exist particular initial data for which one obtains infinitely many entropy-conserving weak solutions by using the convex integration technique. Our result is also true for the isentropic case.
