Answer by pseudo-goldstone for Renormalization in quantum field theory by...
Does this work (that is, are all the regularized integrals associated with Feynman diagrams actually finite in this scheme) or is there some problem I'm not seeing?At least perturbatively (which is the...

I'm a mathematician slowly trying to learn quantum field theory and I have a small question about renormalization, which I still have a shaky understanding of.One common way to explain what's happening...
