A modified renormalization procedure which may avoid use of bare parameters
A new renormalization procedure is introduced via a method that assigns finite values to divergent expressions in quantum field theory. It is shown that this procedure works at the two-loop level in Feynman diagrams with overlapping divergences. Applications to λφ4 theory and quantum electrodynamics...
