Abstract
As a complement to our earlier study of renormalization at the Langevin regularized level, we report here on equivalent renormalization programs for regularized Schwinger-Dyson systems. Both one-loop and iterated loop renormalizations of the Green functions of QCD4 are given, and are shown to be equivalent to the Langevin results. The optional apparent ℏ-renormalization discussed in IV is shown to apply as well to Schwinger-Dyson systems as to Langevin systems.
