The BTZ black hole, the Third Law and gravitational collapse
Aidan M. McSharry, Harvey S. Reall, Jorge E. Santos
We prove that a Third Law of black hole mechanics holds for the BTZ black hole in 3d gravity coupled to matter obeying the dominant energy condition. This law states that initial d…

On the third law of black hole mechanics for supersymmetric black holes
Aidan M. McSharry, Harvey S. Reall
Recently it has been shown that the third law of black hole mechanics can be violated: an exactly extremal Reissner-Nordstrom black hole can form in finite time in gravitational co…
