Résumé:

I will explain a Renormalization Group approach to the study of existence and uniqueness of solutions to stochastic partial differential equations driven by space-time white noise. As an example I sketch a proof of well-posedness and independence of regularization for the $\phi^4$ model in three dimensions recently studied by Hairer and by Catellier and Chouk.
