We will show here that, in a two-dimensional liquid crystal system where di
sclinations are present, the elastic torque cannot balance alone an externa
l torque; a hydrodynamic flow must indeed occur so that the system can reac
h a stationary state. We suggest calling such flows topological flows. We w
ill indicate how they are produced by the Ericksen forces.
