Abstract
Quantum field theories on non-commutative spaces do not have symmetries described by the action of a group. However it is possible to generalize the definition of action of a group to a action of a Hopf algebra. We would like to investigate examples of quantum field theories in non-commutative spaces where the usual symmetries are deformations of the usual ones. (AU)
