On strong solution to the 2D stochastic Ericksen-Leslie system: A Ginzburg-Landau approximation approach

Abstract

In this manuscript, we consider a highly nonlinear and constrained stochastic PDEs modelling the dynamics of 2-dimensional nematic liquid crystals under random perturbation. This system of SPDEs is also known as the stochastic Ericksen-Leslie equations (SELEs). We discuss the existence of local strong solution to the stochastic Ericksen-Leslie equations. In particular, we study the convergence the stochastic Ginzburg-Landau approximation of SELEs, and prove that the SELEs with initial data in ${\mathrm{sh}}^1\times {\mathrm{sh}}^2$ has at least a martingale, local solution which is strong in PDEs sense.
