Gauge theory on the q-deformed two-dimensional Euclidean plane [Formula: see text] is studied using two different approaches. We first formulate the theory using the natural algebraic structures on [Formula: see text], such as a covariant differential calculus, a frame of one-forms and invariant integration. We then consider a suitable star product, and introduce a natural way to implement the Seiberg–Witten map. In both approaches, gauge invariance requires a suitable "measure" in the action, breaking the Eq(2)-invariance. Some possibilities to avoid this conclusion using additional terms in the action are proposed.
