Scale invariance generically implies conformal invariance in three dimensions
A simple proof that scale invariance in scalar models generically implies conformal invariance in three (and four) dimensions is given. It relies on the very structure of the Wilson renormalization group that we first review. If time allows, a rigorous proof will also be given for the special case of the Ising (or ɸ4) model in all dimensions.
