Global structure instability of Riemann solutions for general quasilinear hyperbolic systems of conservation laws in the presence of a boundary

This work is a continuation of our previous work [Z.-Q. Shao, D.-X. Kong, Y.-C. Li, Shock reflection for general quasilinear hyperbolic systems of conservation laws, Nonlinear Anal. TMA 66 (1) (2007) 93 0-124]. In this paper, we study the global structure instability of the Riemann solution u = U(x/t) containing shocks, at least one rarefaction wave for general n x n quasilinear hyperbolic systems of conservation laws in the presence of a boundary. We prove the nonexistence of global piecewise C-1 solution to a class of the mixed initial-boundary value problem for general n x n quasilinear hyperbolic systems of conservation laws on the quarter plane. Our result indicates that this kind of Riemarm solution u = U(x/t) mentioned above for General n x n quasilinear hyperbolic systems of conservation laws in the presence of a boundary is globally structurally unstable. Some applications to quasilinear hyperbolic systems of conservation laws arising from physics and mechanics are also given. (c) 2006 Elsevier Inc. All rights reserved.
