Abstract

A system of Whitham equations for the derivative nonlinear Schrödinger equation in the Riemann form was used to analyze possible types of decay of discontinuities which accompany the overturning of the simplest quasilongitudinal nonlinear Alfvén wave. A whole class of structures is found which are formed when the discontinuities decay into two simple collisionless shock waves without forming a plateau between them. Different types of decay of the initial discontinuities are considered for cases when the overturning of the Alfvén wave is modulationally stable.
