Analysis and Numerics on a 2D Dynamic Q-Tensor Model
Prof. Xiang Xu
Department of Mathematics and Statistics, Old Dominion University, USA

We consider a four-elastic-constant Landau-de Gennes energy characterizing nematic liquid crystal configurations described using the Q-tensor formalism. The energy contains a cubic term and is unbounded from below. We study dynamical effects produced by the presence of this cubic term by considering an L^2 gradient flow generated by this energy. We work in two dimensions and make analysis in both the PDE and numeric aspects.
