Perturbative series and the 1/N expansion for the QED β-function

Abstract
A comparison of the perturbative series and the 1/N expansion for the QED renormalization group β-function in the Minimal Subtraction scheme is performed. The good agreement between two expansions is found which proves that the MS β-function is under perfect perturbative control.
