    • Lie theory for asymptotic symmetries in general relativity : The BMS group 

      Prinz, David Nicolas; Schmeding, Alexander (Peer reviewed; Journal article, 2022)
      We study the Lie group structure of asymptotic symmetry groups in General Relativity from the viewpoint of infinite-dimensional geometry. To this end, we review the geometric definition of asymptotic simplicity and emptiness ...

    • Lie theory for asymptotic symmetries in general relativity : The NU group 

      Prinz, David Nicolas; Schmeding, Alexander (Peer reviewed; Journal article, 2022)
      We study the Newman--Unti (NU) group from the viewpoint of infinite-dimensional geometry. The NU group is a topological group in a natural coarse topology, but it does not become a manifold and hence a Lie group in this ...
