Linear orbital stability of discrete shock profiles for systems of conservation laws

Résumé

We prove the linear orbital stability of spectrally stable stationary discrete shock profiles for conservative finite difference schemes applied to systems of conservation laws. The proof relies on a precise description of the pointwise asymptotic behavior of the Green's function associated with those discrete shock profiles, improving on the result of Godillon [God03]. The main novelty of this stability result is that it applies for a fairly large family of schemes that introduce some artificial viscosity and most importantly, that we do not impose any weakness assumption on the shock.
