| Abstract: |
| In this paper we study a system of nonlinear partial differential equations mod- elling the electrokinetics of a nematic electrolyte material consisting of various ions species contained in a nematic liquid crystal. [The system coupling a Nernst-Planck system for the ions concentrations with a Maxwell's equation of electrostatics governing the evolution of the electrostatic potential, an incompressible Navier-Stokes equation for the velocity field and a non-smooth Allen-Cahn type equation for the nematic director field.] We use energy method to prove the local existence of classical solutions with large initial data and the global existence of classical solutions with small initial data. |
