Abstract
A general method for solving the two-dimensional time-dependent ideal MHD equations is developed when the Alfven-Mach number is small and th e Mach number large in comparison with unity. The method is applied to the problem of the time-dependent nonlinear collapse of an X-type neu tral point. A current sheet is formed which grows in a self-similar ma nner.
