WebRenormalization Group Methods Porter Williams It is a truism, in physics if not in philosophy, that in order to study phys-ical behavior at a particular scale one is best served by using degrees of free-dom de ned at (or suitably near) that scale. If one wants to study the classi-cal behavior of a simple Web1 The Concept of the Renormalization Group The key idea of the renormalization group results from comparing phenomena at different length/energy scales. A QFT is defined by an action functional of the fields S[φ;gi] which depends a priori on an infinite number of parameters: the coupling constants in a general sense so including mass ...
