Using group-theoretical methods and numerical simulations we show how to act
on the topological charge of individual vortices in Bose-Einstein condensates
by using control potentials with appropriate discrete symmetries. As examples
of our methodology we study charge inversion and vortex erasing by acting on a
set of control laser gaussian beams generating optical dipole traps.
