Conformal Carroll groups and BMS symmetry

arXiv:1402.5894 · doi:10.1088/0264-9381/31/9/092001

Abstract

The Bondi-Metzner-Sachs (BMS) group is shown to be the conformal extension of Levy-Leblond's "Carroll" group. Further extension to the Newman-Unti (NU) group is also discussed in the Carroll framework.
