✦ Synopsis

We present a formal calculation of the infrared singularity structure of the fermion propagator in QED based on the Faddeev-Kulish asymptotic solution. The Renormalization program is reviewed in the context of the BPHZ subtraction scheme and a refinement of the Renormalization group methods is employed to study the infrared singularities in perturbation theory.

We analyse some redefinitions of the energy-momentum tensor of Classical Electrodynamics. Usually it has been considered as a necessary and sufficient criterion for redefining the energymomentum tensor that the new tensor yields the "true" equation of motion of the electron, that is, the Lorentz-Di
