Abstract: (Elsevier)

We extend the perturbative analysis of the two-dimensional Gross-Neveu model by cimputing within the MS scheme the three-loop renormalization functions β,γ, and γ m in a two-parameter version of the model appropriate to the discussion of the RG properties of the effective potential, whose perturbative expansion is performed to the same order.
