[Lois de conservation scalaires avec des conditions non linéaires au bord]
Cette Note est dédiée aux résultats d'unicité des solutions du problème div sur avec la condition initiale sur Ω et les conditions non linéaires sur ; ici désigne un graphe maximal monotone sur . Nous proposons une interprétation de la condition formelle « » qui généralise celle de Bardos–LeRoux–Nédélec ; nous introduisons les notions de solutions entropiques et solutions processus entropiques. Nous montrons l'unicité et argumentons en faveur de notre interprétation de la condition au bord.
This Note deals with uniqueness and continuous dependence of solutions to the problem on with initial condition on Ω and with (formal) nonlinear boundary conditions on , where stands for a maximal monotone graph on . We suggest an interpretation of the formal boundary condition which generalizes the Bardos–LeRoux–Nédélec condition, and introduce the corresponding notions of entropy and entropy process solutions using the strong trace framework of E.Yu. Panov. We prove uniqueness and provide some support for our interpretation of the boundary condition.
