报告题目：Ericksen-Leslie's hyperbolic liquid crystal model

摘要：This talk is devoted to the Ericksen-Leslie's hyperbolic system for incompressible liquid crystal model, where the direction of liquid crystal molecules satisfies a wave map equation with an acoustical metric.

I will introduce the almost global well-posedness for small and smooth initial data near the constant equilibrium in low dimensions. I will also present the main difficulties and key ingredients in the proof. Our proof relies on the idea of vector-field method and ghost weight method. This is joint work with Lifeng Zhao and Ning Jiang.
