Ill-posedness of incompressible Kelvin-Helmholtz problem with transverse magnetic field
Binqiang Xie, Boling Guo, Bin Zhao
In this paper, we prove the linear and nonlinear ill-posedness of the well-known Kelvin-Helmholtz problem of the incompressible ideal magnetohydrodynamics (MHD) equations with tran…

Ill-posedness of the Kelvin-Helmholtz problem for compressible Euler fluids
Binqiang Xie, Bin Zhao
In this paper, when the magnitude of the Mach number is strictly between some fixed small enough constant and , we can prove the linear and nonlinear ill-posedness of the…
