A uniqueness and regularity criterion for Q-tensor models with Neumann boundary conditions. Differential and integral equations, 28 (5-6), 537-552.0893-4983http://hdl.handle.net/11441/40264We give a regularity criterion for a Q-tensor system modeling a nematic Liquid Crystal, under homogeneous Neumann boundary conditions for the tensor Q. Starting of a criterion only imposed on the velocity field u two results are proved; the uniqueness of weak solutions and the global in time weak regularity for the time derivative (∂tu, ∂tQ). This paper extends the work done in [8] for a nematic Liquid Crystal model formulated in (u, d), where d denotes the orientation vector of the liquid crystal molecules.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Nematic liquid crystalQ-tensor modelregularity criteriauniqueness criteriaNeumann boundary conditionsinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
