摘要:
We consider the steady compressible Navier-Stokes equations in the isentropic regime in a bounded domain of R-3. We show that the renormalized continuity equation holds even if the density is not square integrable. We use this result to prove existence of weak solutions under the sole hypothesis gamma > 3/2 for the adiabatic constant.
