A conformal infinity approach to asymptotically $AdS_{2} \times S^{n - 1}$ spacetimes

Gregory J. Galloway, Melanie Graf, Eric Ling

It is well known that the spacetime $AdS_{2} \times S^{2}$ arises as the `near horizon' geometry of the extremal Reisser-Nordstrom solution, and for that reason it has been studi…

Singularity theorems for $C^{1}$ -Lorentzian metrics

Melanie Graf

Continuing recent efforts in extending the classical singularity theorems of General Relativity to low regularity metrics, we give a complete proof of both the Hawking and the Penr…

Rigidity of asymptotically $A d S_{2} \times S^{2}$ spacetimes

Gregory J. Galloway, Melanie Graf

The spacetime $A d S_{2} \times S^{2}$ is well known to arise as the 'near horizon' geometry of the extremal Reissner-Nordstrom solution, and for that reason it has been studied in conne…
