报告题目:Local well-posedness of the free-surface inviscid two phase flow model

报告摘要:We investigate a free boundary problem for the inviscid two-phase flow model with moving physical vacuum boundary, which is a degenerate and characteristic hyperbolic system of conservation laws. Based a suitable transformation, a special degenerate parabolic approximation and delicate uniform energy estimates, we prove the existence and uniqueness of the local weak solutions. This can be regarded as a generalization of the results in [Coutand, D., Shkoller, S.,  Commun. Pure Appl. Math., 64: 328-366, 2011] from single-phase gas model to two-phase gas-liquid model.
