An interesting problem in gas and fluid dynamics is to understand the behavior of vacuum states, namely the behavior of the system in the presence of vacuum. A particular interest is so called physical vacuum which naturally arises in physical problems. The main difficulty lies in the fact that the physical systems become degenerate along the boundary.  I'll present the well- posedness result of 3D compressible Euler equations for polytropic gases. This is a joint work with Nader Masmoudi.
