Abstract |
Conserved charges associated with large gauge symmetries and Bondi-Metzer-Sachs symmetries of
asymptotically Minkowski spacetime have been recently shown to give new "soft hair" for black holes --
beyond mass, charge and angular momentum. In this talk, I will outline a study of the constraint on dynamics
due to these new symmetries. I will prove that they only constrain long-time, infrared dynamics, in a way that
is completely factorizable. Factorization implies in particular that soft hair does not constrain the ``hard"
physical processes that account for black hole microstates. |
