More Complicated Interactions and the General Structure of the Renormalization Group

  • Lothar Schäfer

Abstract

Having at hand the techniques of perturbation theory and the renormalization group we are prepared to consider once more a question of fundamental importance: can we justify our simple model? Are we really allowed to ignore many-body interactions or other features of a microscopically realistic description of the polymer solution? On a very superficial level we discussed this problem in Sect. 2.2. Let us critically reconsider that argument.
