The Penrose singularity theorem, MOTS stability, and horizon topology in weighted spacetimes
Eric Ling, Argam Ohanyan, Eric Woolgar
We consider versions of the Penrose singularity theorem and the Hawking horizon topology theorem in weighted spacetimes that contain weighted versions of trapped surfaces, for arbi…

Extreme 5-dimensional black holes with SU(2)-symmetric horizons
Eric Bahuaud, Sharmila Gunasekaran, Hari K Kunduri +1
We show that the near horizon geometry of 5-dimensional extreme (i.e., degenerate) stationary vacuum black holes, with or without cosmological constant, whose event horizons exhibi…

Deformations of the Kerr-(A)dS Near Horizon Geometry
Eric Bahuaud, Sharmila Gunasekaran, Hari K Kunduri +1
We investigate deformations of the Kerr-(A)dS near horizon geometry and derive partial infinitesimal rigidity results for it. The proof comprises two parts. First, we follow the an…
