Title
Characteristic black hole gluing in spherical symmetry and applications
Abstract
We construct examples of black hole formation from regular, one-ended asymptotically flat Cauchy data for the Einstein–Maxwell-charged-scalar field system in spherical symmetry which are exactly isometric to subextremal or extremal Reissner–Nordstrom after a finite time along the event horizon. Moreover, these can be constructed so that the apparent horizon coincides with that of a Schwarzschild solution at earlier times. This is relevant to the so-called third law of black hole thermodynamics.
The main step in the construction is C^k-characteristic gluing of a cone in Minkowski space to a Reissner–Nordström event horizon with specified charge to mass ratio e/M.
Please note that the seminar will take place in person in room 658 of Huxley Building.
