摘要:It is well-known that vortex sheets for incompressible Euler equations are not stable (called Kelvin-Helmholtz instability). However, in 1953, Syrovatskij derived a stability condition which indicates that when the magnetic field is sufficiently strong, current-vortex sheets for MHD equations could be probably weakly stable. In this talk, we will talk about the existence for the incompressible current-vortex sheets in Sobolev spaces, which gives a rigorously confirmation on that incompressible current-vortex sheets are non-linearly stable under Syrovatskij's stability condition.
