Add to ORKGUsing the method of perturbative renormalization developed by Epstein and Glaser (ibid., vol.XIX, no.3, p.211 (1973)) it is shown that Green's functions exist for theories with massless particles such as QED, and lambda : phi /sup 2n/ theories. Growth properties are given in momentum space. In the case of QED, it is also shown that one can perform the physical mass renormalization. (6 refs)
