摘要

We consider an initial boundary value problem for a symmetrizable mixed hyperbolic-parabolic system of conservation laws with a small viscosity epsilon, u(t)(epsilon)+F(u(epsilon))(x)=epsilon(B(u(epsilon))u(x)(epsilon))(x). When the boundary is noncharacteristic for both the viscous and the inviscid system, and the boundary condition dissipative, we show that u(epsilon) converges to a solution of the inviscid system before the formation of shocks if the amplitude of the boundary layer is sufficiently small. This generalizes previous results obtained for B invertible and the linear study of Serre and Zumbrun obtained for a pure Dirichlet's boundary condition. [References: 15]
