摘要：The compressible MHD equations model electrically conducting fluids. The simplest model are the ideal MHD equations, where one assumes an infinite electric conductivity. This model is widely studied in the mathematical literature. From a physical point of view, the conditions for the ideal MHD approximation break down at current sheets. The resistive MHD equations having finite electric conductivity and thus introducing magnetic diffusivity to the model, no matter how small, are then still a good approximation.Mathematically, the resistive MHD equations form a hyperbolic-parabolic system, we prove local in time well-posedness.
