U(1) gauge field theory on kappa-Minkowski space

In this talk we present some results of the study of U(1) gauge field theory on the kappa-deformed Minkowski spacetime. We construct the conserved gauge current, fix part of the ambiguities in the Seiberg-Witten map and obtain an effective U(1) action invariant under the action of the undeformed Poincare group. We discuss possibilities of constructing an appropriate geometric picture.
