Free field theory at null infinity and white noise calculus: a BMS invariant dynamical system

Abstract

In the context of asymptotically flat spacetimes we exploit techniques proper either of white noise analysis either of dynamical systems in order to develop the Lagrangian and the Hamiltonian approach to a BMS invariant field theory at null infinity.
