Abstract:
Using the Seiberg-Witten map, we obtain a quantum electrodynamics on a
noncommutative space, which has arbitrary charge and keep the gauge
invariance to at the leading order in theta. The one-loop divergence and
Compton scattering are reinvestigated. The noncommutative effects are larger
than those in ordinary noncommutative quantum electrodynamics.
