Abstract:The compressible Navier-Stokes equation with general pressure and density dependent viscosities is investigated. We identify conditions on these quantities ensuring the compactness of weak solutions to the equation. In particular, this compactness property holds true for pressures which might not be monotone. Our arguments rely on the BD entropy and exploit the idea of renormalized weak solutions in velocity for the momentum equation. This is joint work with Quoc-Hung Nguyen.
