L[sup 1]-stability of stationary discrete shocks

OSTI ID:6655216
The nonlinear stability in the L[sup p]-norm, p [ge] 1, of stationary weak discrete shocks for the Lax-Friedrichs scheme approximating general m [times] m systems of nonlinear hyperbolic conservation laws is proved, provided that the summations of the initial perturbations equal zero. The result is proved by using a both weighted estimate and characteristic energy method based on the internal structures of the discrete shocks and the essential monotonicity of the Lax-Friedrichs scheme. 13 refs.
