May 23, 2017 at 14:45	comment	added	Adam		Ok, I've found the book. What they are doing here is a dirty way of setting up a RG procedure (that is, they know what to do because they know RG, and cook up some rules to find the correct result). In principle, one could also do that for standard QFT... If you don't want to just accept their rules, set up a RG procedure from the equivalent FT for KPZ, it will be much more satisfying.

May 23, 2017 at 14:22	comment	added	Victor Buendía		Thanks for the detailed answer. However, the KPZ equation is a model for a non-equilibrium process, so I cannot define a partition function. Still I could translate my stochastic PDE to a field theory and define an action, but I would have to add an auxiliar field. Any clue your method with the non-equilibrium process?
