Jabin, arXiv:1507.04629, (2015)]) which concerns the resolution of two longstanding problems: Global existence of weak solutions for compressible Navier-Stokes equations with thermodynamically unstable pressure and with anisotropic stress tensor. We focus here on a Stokes-like system which can for instance model flows in a compressible tissue in biology or in a compressible porous media in petroleum engineering. This allows us to explain, on a simpler but still relevant and important system, the tools recently introduced by the authors and to discuss the important results that have been obtained on the compressible Navier--Stokes equations. It is finally a real pleasure to dedicate this paper to G. Metivier for his 65's Birthday.", "revisions": [ { "version": "v1", "updated": "2016-02-13T20:02:41.000Z" } ], "analyses": { "keywords": [ "global weak solutions", "compactness criterion", "compressible media", "physical situations", "compressible navier-stokes equations" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2016arXiv160204373B" } } }
