摘要：

We prove existence of weak solutions to the compressible Navier-Stokes system in barotropic regime (adiabatic coefficient >3/2, in three dimensions, >1 in two dimensions) with large velocity prescribed at the boundary and large density prescribed at the inflow boundary of a bounded Lipschitz piecewise regular domain, without any restriction neither on the shape of the inflow/outflow boundaries nor on the shape of the domain. The result applies also to pressure laws that are non-monotone on a compact portion of the interval [0, infinity). We prove existence of weak solutions to the compressible Navier-Stokes system in barotropic regime (adiabatic coefficient >3/2, in three dimensions, >1 in two dimensions) with large velocity prescribed at the boundary and large density prescribed at the inflow boundary of a bounded Lipschitz piecewise regular domain, without any restriction neither on the shape of the inflow/outflow boundaries nor on the shape of the domain. The result applies also to pressure laws that are non-monotone on a compact portion of the interval [0, infinity).
