## Problèmes aux limites pour des systèmes hyperboliques non linéaires de deux équations à une dimension d’espace. (Boundary conditions for nolinear 2$$\times 2$$ hyperbolic systems of conservation laws).(French)Zbl 0632.35040

We study two types of boundary conditions for hyperbolic systems of conservation laws. The first one comes from the viscosity method, the second from the solution of the Riemann problem.
