Spacetime structure near generic horizons and soft hair
Daniel Grumiller, Alfredo Pérez, M. M. Sheikh-Jabbari +2
We explore the spacetime structure near non-extremal horizons in any spacetime dimension greater than two and discover a wealth of novel results: 1. Different boundary conditions a…
Boundary conditions for General Relativity in three-dimensional spacetimes, integrable systems and the KdV/mKdV hierarchies
Emilio Ojeda, Alfredo Pérez
We present a new set of boundary conditions for General Relativity on AdS, where the dynamics of the boundary degrees of freedom are described by two independent left and right…
Bondi-Metzner-Sachs invariance and electric-magnetic duality
Claudio Bunster, Andrés Gomberoff, Alfredo Pérez
We exhibit a Hamiltonian formulation, both for electromagnetism and gravitation, in which it is not required that the Bondi "news" vanish, but only that the incoming news be equal…
