Title: Local solutions of RG flow equations and the Nash-Moser theorem

Abstract: During this talk we shall discuss the derivation of a functional Renormalisation Group equation for the effective action of an interacting quantum field theory in the Lorentzian setting when a local regulator consisting in the addition of a mass is employed. The flow equation for mass rescalings is then studied using the renown Nash-Moser theorem and hence, a proof of existence of solutions is obtained in that context.
