On s’intéresse à des systèmes symétriques hyperboliques multidimensionnels en présence d’une semilinéarité. Il est bien connu que ces systèmes admettent des solutions discontinues, régulières de part et d’autre d’une hypersurface lisse caractéristique de multiplicité constante. Une telle solution étant donnée, on montre que est limite quand de solutions du système perturbé par une viscosité de taille . La preuve utilise un problème mixte parabolique et des développements de couches limites. On s’intéresse aussi à des singularités plus faibles comme des sauts de dérivées.
We are interested in some multidimensional semilinear symmetric hyperbolic systems. It is well known that these systems have some discontinuous solutions which are regular outside of a smooth hypersurface characteristic of constant multiplicity. We suppose that such a solution is given and we show that is the limit, when , of solutions of the system perturbated by a viscosity of size . The key tools of the proof are a parabolic boundary problem and boundary layers expansions. We also consider weaker singularities as derivatives jumps.
