En plusieurs variables d’espace, les chocs scalaires entre deux constantes ne sont pas nécessairement des chocs plans. Nous les décrivons en détail. Puis nous prouvons leur stabilité asymptotique en distance , sous l’hypothèse qu’ils ne sont pas caractéristiques. Pour un flux général, notre résultat suppose que la donée initiale est à valeurs dans l’intervalle . Pour l’équation de Burgers multi-D, il est valable pour des perturbations arbitrairement grandes.
In several space dimensions, scalar shock waves between two constant states are not necessarily planar. We describe them in detail. Then we prove their asymptotic stability in -distance, assuming that they are uniformly non-characteristic. Our result is conditional for a general flux, while unconditional for the multi-D Burgers equation.
