The seminar is sponsored by NYU-ECNU Institute of Mathematical Sciences at NYU Shanghai.
Abstract:
In this talk, we will give a general introduction to various models for nematic liquid crystals such as Onsager's hard rod model, Landau De-Gennes Q-tensor model and Oseen-Frank model. Some analytic results concerning the relationship between these models will be discussed. For example, by means of the Bingham closure procedure, Onsager's model can be reduced to the Q-tensor model; And through the uniaxial limit, both Onsager's model and Landau De-Gennes model will lead to the Oseen-Frank model.
