The BMS group at spatial infinity
Dr. Marc Henneaux de la Université de Bruxelles


Previous investigations of gravity at spatial infinity in the asymptotically flat context gave no sign of the BMS group. A similar situation arises with electromagnetism concerning angle-dependent u(1)-transformations.  The talk will indicate how to solve this somewhat uncomfortable situation through a suitable choice of boundary conditions.  While the ideas apply to both gravity and electromagnetism, the analysis will be mostly carried out in the more familiar electromagnetic context.
