The ADM description of the Bondi-Metzner-Sachs group of asymptotically flat spaces
A review of asymptotic symmetries of gravity in the asymptotically flat context will be given following the Hamiltonian (ADM) approach. General features (such as the form of the symmetry generators and the structure of the algebra) will be explained. The talk will also cover logarithmic supertranslations and explain how they lead to a remarkable simplification of the infinite-dimensional BMS algebra.
