摘要: In this talk, we will discuss a recent global existence result on the Poiseuille flow of nematic
liquid crystals via full Ericksen-Leslie model. The existing results on the Ericksen Leslie model for
the liquid crystals mainly focused on the parabolic and elliptic type models by omitting the kinetic
energy term. In this recent progress, we established a new method to study the full model. A singularity
formation result will also be discussed, together with the global existence result showing that the
solution will in general live in the Holder continuous space. The earlier related result on the stability of
variational wave equation using the optimal transport method, and the future work on other wave
equations will also be discussed. The talk is on the joint work with Tao Huang & Weishi Liu.
