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 WebThe "Renormalization Group" Game Okay, now I want to talk about the renormalization group. I'm deliberately going to simplify things to the point where I'm verging on inaccuracy, but hopefully I won't actually say anything actually false. So, let's recall what we've got. We have a quantum field theory described by a Lagrangian with a bunch of ...
