Stationary boundary value problems for 3D compressible Navier-Stokes equations for di-atomic gases

The 3D-Navier-Stokes system for a steady compressible isentropic fluid, with a pressure law $p=\rho^\gamma$ in a bounded domain is considered. We extend the existence theory to the range $\gamma\geq 4/3$ in isomass case and to the range $\gamma>1$ in the isoenergy case.
