Summary. This paper is concerned with polynomial decay rates of perturbations to stationary discrete shocks for the Lax-Friedrichs
scheme approximating non-convex scalar conservation laws. We assume that the discrete initial data tend to constant states
as , respectively, and that the Riemann problem for the corresponding hyperbolic equation admits a stationary shock wave. If
the summation of the initial perturbation over is small and decays with an algebraic rate as , then the perturbations to discrete shocks are shown to decay with the corresponding rate as . The proof is given by applying weighted energy estimates. A discrete weight function, which depends on the space-time variables
for the decay rate and the state of the discrete shocks in order to treat the non-convexity, plays a crucial role.
