Abstract: We study the largetime behavior of discrete solutions of the LaxFriedrichs finite difference equations for hyperbolic systems of conservation laws. The initial data considered here are small and tend to a constant state at . We show that the solutions tend to the discrete diffusion waves at the rate in , , with being an arbitrarily small constant. The discrete diffusion waves can be constructed from the selfsimilar solutions of the heat equation and the Burgers equation through an averaging process.
