Abstract
We consider the Navier–Stokes equations for the motion of compressible viscous flows in a halfspace mathbbRn + n = 2 3 with the noslip boundary conditions We prove the existence of a global weak solution when the initial data are close to a static equilibrium The density of the weak solution is uniformly bounded and does not contain a vacuum the velocity is Hölder continuous in x t and the material acceleration is weakly differentiable The weak solutions of this type were introduced by D Hoff in Arch Ration Mech Anal 114115–46 1991 Commun Pure and Appl Math 55111365–1407 2002 for the initialboundary value problem in Omega = mathbbRn and for the problem in Omega = mathbbRn + with the Navier boundary conditions
