Title: Stability of a hydrodynamic discontinuity

Abstract: While looking from a far field at a discontinuous front separating incompressible ideal fluids of different densities, we identify two qualitatively different behaviors of the front - unstable and stable - depending upon whether the energy flux produced by the perturbed front is large or small compared to the flux of kinetic energy across the planar front. Landau's solution for the Landau - Darrieus instability is consistent with one of these cases.
