Undercompressive Shock Waves and the Dafermos Regularization

Abstract: For a system of conservation laws in one space dimension, we identify all structurally stable Riemann solutions that include only shock waves. Shock waves are required to satisfy the viscous profile criterion for a given viscosity $(B(u)u_ x)_x$. Undercompressive shock waves are allowed. We also show that all such Riemann solutions have nearby smooth solutions of the Dafermos regularization with the given viscosity.
