Postdoc Research Fellow Zhewen Feng is giving a talk in our Asia-Pacific Analysis and PDE Seminar on 

The Beris-Edwards system for nematic liquid crystal flows

Abstract:

The Landau-de Gennes theory is the most general continuum theory for nematic liquid crystals. However, Ball and Majumdar (Mol. Cryst. Liq. Cryst., '10) found an example that the original Landau-de Gennes energy functional is unbounded from below; thus, there is no global energy minimizer. In this talk, we consider a new Landau-de Gennes energy functional proposed by F. and Hong (CVPDE '22) that the new energy is bounded from below. Furthermore, we shall present our recent work in collaboration with Min-Chun Hong and Yu Mei on the existence of solutions for the uniaxial Beris-Edwards system based on the new energy with a scaling analysis.

Chair: Ben Goldys (The University of Sydney)
