摘要：

By considering corrections to the asymptotic scaling functions of the photon and electron in quantum electrodynamics with N(f) flavors, we solve the skeleton Dyson equations at O(1/N(f)) in the large N(f) expansion at the d-dimensional critical point of the theory and deduce the critical exponent beta'(g(c)), in arbitrary dimensions, and subsequently present a method for computing higher order corrections to beta(g).
