Abstract

To search the infrared behaviour of the propagator in three dimensional QED ordinary perturbative method is not appropreate because of its bad infrared divergences[4].Assuming spectral representation and LSZ reduction formula,we evaluate the infrared behaviour or the mass singularity of the fermion propagator in three dimensional QED as in four dimension.In… (More)
