E. Godlewski et Pa. Raviart, The linearized stability of solutions of nonlinear hyperbolic systems of conservation laws - A general numerical approach, MATH COMP S, 50(1-4), 1999, pp. 77-95
We study the linearized stability of a discontinuous solution of a multidim
ensional hyperbolic system of conservation laws by linearizing the system a
round the basic solution; the resulting linearized system has discontinuous
coefficients and involves nonconservative products. We propose a direct ap
proach of the problem which introduces measure solutions and gives a natura
l meaning to the nonconservative product. This approach leads to simple num
erical schemes. (C) 1999 IMACS/Elsevier Science B.V. All rights reserved.
