报告摘要:In 1992, Hsiao and Liu (CMP, 1992) showed that the solution to the p-system with damping (PSD) time-asymptotically converges to the diffusion wave of the porous media equation (PME). Recently, we proposed a time asymptotic expansion around the diffusion wave. In this talk, we rigorously justify the expansion by the approximate Green function method. Moreover, the large time behavior of the solution to PSD is accurately characterized by the time asymptotic expansion.
