Strong ill-posedness for the MHD system in the supercritical regime: inviscid and viscous

Zhenyu Wan, Weikui Ye, Zhaoyang Yin

This paper is concerned with the Cauchy problem for the 3D incompressible magnetohydrodynamic (MHD) equations in supercritical Sobolev spaces. It is well known that the system is l…
