Abstract
Starting from their generating functional, we investigate the structure of the finite and divergent parts of propagators in quantum electrodynamics. A renormalizability condition is expressed by means of a set of recursion formulas between the finite parts of radiative corrections of the generating functional; this condition is the algebraic formulation of Salam's rule for the extraction of finite parts from divergent integrals. The former sets of equation should finally allow the actual computation of the radiative correction of higher orders.Keywords
