Convergence of the Ginzburg-Landau approximation for the Ericksen-Leslie system

Abstract

We establish the local well-posedness of the general Ericksen-Leslie system in liquid crystals with the initial velocity and director field in $H^1\times H_b^2$. In particular, we prove that the solutions of the Ginzburg-Landau approximation system converge smoothly to the solution of the Ericksen-Leslie system for any $t\in (0,T^{\ast })$ with a maximal existence time $T^{\ast }$ of the Ericksen- Leslie system.
