报告内容简介：

 In this talk, we discuss a brief introduction to Landau - de Gennes theory for Liquid Crystals and   investigate the structure and stability of the isotropic-nematic interface in 1-D. In the absence of the anisotropic energy, the uniaxial solution is the only global minimizer. In the presence of the anisotropic energy, the stability of the uniaxial solution with the homeotropic anchoring depends on the elastic constants. We also present many interesting open questions, some of which are related to De Giorgi conjecture. This is a joint work with Wei Wang, Pingwen Zhang and Zhifei Zhang.
