The system consists of the Navier-Stokes equations, with an extra stress tensor depending on the elastic forces of the liquid crystal, coupled with an Allen-Cahn system for the Q-tensor variable. This problem has a dissipative in time free-energy which leads, in particular, to prove the existence of global in time weak solutions. We analyze the large-time behavior of the weak solutions. By using a Lojasiewicz-Simon's result, we prove the convergence as time goes to infinity of the whole trajectory to a single equilibrium.", "revisions": [ { "version": "v1", "updated": "2018-05-07T10:57:45.000Z" } ], "analyses": { "subjects": [ "35B40", "35D30", "35K55", "35Q30", "35Q35", "76A15", "76D05" ], "keywords": [ "global weak solutions", "q-tensor problem", "convergence", "nematic liquid crystals", "time weak solutions" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable" } } }
