报告摘要：In this talk, we will introduce some of our results on the large-time behaviors of solutions to the one-dimensional compressible two-phase model with free boundaries. Specifically, for both the case of constant viscosity and the case of degenerate viscosity, we prove the decay estimates for the solutions of the model in both the vacuum free boundary setting and non-vacuum free boundary setting. In particular, we derive the optimal pointwise decay estimates of the mass-related function of the two-phase flow for the case of vacuum free boundary.
