| 14:00 - 15:00 Weekly Seminar HEPCo Group Barnich--Troessaert Bracket as a Dirac bracket School PHYSICS Abstract: The main goal of this seminar is to discuss how the ADM phase space for general relativity can be split into edge modes and radiative modes and how these two different components can each be understood as genuine phase spaces for themselves. Each of these smaller phase spaces is equipped with a symplectic structure. The symplectic structure on the radiative phase space defines the familiar Poisson commutation relations for the asymptotic shear. Following the argument given in arXiv:2104.08377, it will be shown that the Poisson bracket for the edge modes (obtained by formally imposing second-class constraints on th ... |
