| Abstract: | By means of maximum principle for nonlinear hyperbolic systems, the results given by HSIAO Ling and D. Serre was improved for Cauchy problem of compressible adiabatic flow through porous media, and a complete result on the global existence and the blow_up phenomena of classical solutions of these systems. These results show that the dissipation is strong enough to preserve the smoothness of 'small' solution. |
