| Abstract: | A semilinear two-speed symmetric hyperbolic systems with the boundary condition which satisfies a dissipative condition, for the usual pattern of reflection of one discontinuous wave on a boundary,using prior estimate method, thefollowing conclusion is obtained:when a given bounded solution is L2-conormalwith respect to the characteristic hypersurfaces in the past time,then this solutioncan be extended as a bounded and L2-conormal solution in the future time. |
