In this paper, we investigate the controllability of the point vortex systemby means of a single vortex. The point vortex system is a well-known simpliedmodel for the incompressible Euler equation, where the vorticity isconcentrated in a nite number of Dirac masses. We use one of the vortices as acontrol, and prove that by suitably choosing its trajectory, we can drive allother vortices to a given prescribed position in arbitrary time.
