«Asymptotic Symmetries in gauge theories with emphasis on gravity»

Abstract: Asymptotic symmetries, sometimes also known as «large gauge transformations», provide important dynamical information on theories with a gauge freedom formulated on spacetimes having a «boundary at infinity».   A review of asymptotic symmetries will be given following the Hamiltonian approach. General features (such as the form of the symmetry generators and the structure of the algebra) as well as specific examples will be covered.  A particular focus will be paid to gravity in the asymptotically flat context, where the relevant asymptotic symmetry algebra is the infinite-dimensional BMS algebra.
