Abstract:
 We obtain the convergence rate estimates for singular limits of the compressible ideal magneto-hydrodynamic equations when the Mach and Alfven numbers tend to zero at different rates. Since the uniform boundedness of the first time derivative of solutions isn’t propagated for positive time in general for three-scale system, it is shown that the issue of convergence rates for three-scale singular limits is much more complicated than for the classical two-scale.This is a recent joint work with Bin Cheng from Surrey university and Steve Schochet from Tel-Aviv university.
