Zero-viscosity limit of the compressible Navier-Stokes equations in the analytic setting

In this paper, we study the zero-viscosity limit of the compressible Navier-Stokes equations in a half-space with the non-slip boundary condition. We justify the Prandtl boundary layer expansion for the analytic data: the compressible Navier-Stokes equations can be approximated by the compressible Euler equations away from the boundary and by the compressible Prandtl equation near the boundary.
