Abstract: | In this paper, we consider the large perturbation around the viscous shock of the scalar conservation law with viscosity in one dimension case. We divide the time region into t ? T 0 and t > T 0 for a fixed constant T 0 when applying energy method. Since T 0 is fixed, the case t ? T 0 is easy to deal with and when t > T 0, from the decaying property of the solution, there is a priori estimate for the solution. Thus we can succeed to control the nonlinear term and get the pointwise estimate for the perturbation by the weighted energy method. |
