Description
A few years ago Strominger argued that the BMS4 algebra, usually
defined at null infinity, should be regarded as a true symmetry of
gravitational evolution of asymptotically flat space-times. This
implies the existence of an infinite tower of conserved quantities
and brings new insight to various problems like gravitational
scattering or black-holes evaporation. In this talk, I will show how
BMS4 algebra arises as a symmetry at spatial infinity and prove the
associated conservation laws conjectured by Strominger
