报告题目：Convergence of Weak Solutions from The Landau-De-Gennes Theory to The Ericksen-Leslie Theory.

报告摘要：In this talk I will discuss the asymptotic connections between the Landau-de-Gennes theory and the Ericksen-Leslie theory for nematic liquid crystals. I will present the main results that  the weak solutions to the Beris-Edwards equations converge to the ones to the Ericksen-Leslie equations in 2-dimension as the elastic coefficient tends to zero. The key point is that the limiting weak solutions to the Ericksen-Leslie system may have singularities. The main difficulties and ideas of analysis will be discussed. This is based on  joint works with Dr. Xiaotao Zhang.
