Recording of a joint talk with David Prinz (University of Potsdam) in the analysis seminar of S. Paycha. In this talk we give a brief introduction to the Bondi-Metzner-Sachs (BMS) group and the Newman-Unti (NU) group for asymtotically flat space times. Then the (infinite-dimensional) Lie group structure of these groups is discussed.
