Asymptotic symmetries: from low to high spins

Abstract:
Assigning the asymptotic behaviour of physical observables is part of the definition of a theory that, for gauge theories, may enforce a non-trivial structure of the corresponding asymptotic symmetry group. We shall review the basic feature of the latter for spin-one gauge theories and for asymptotically flat gravity, while also exploring its relevance in some less customary scenarios, like higher-spin gauge theories and dual formulations.
