Wilson's Renormalization Group and Its Applications in Perturbation Theory
Abstract
Description
The general prescription for constructing the continuum limit of a field theory is explained using Wilson's renormalization group. We then formulate the renormalization group in perturbation theory and apply it to the four dimensional phi4 theory and QED.
