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…

Rigidity of quasi-Einstein metrics: The incompressible case
Eric Bahuaud, Sharmila Gunasekaran, Hari K Kunduri +1
As part of a programme to classify quasi-Einstein metrics on closed manifolds and near-horizon geometries of extreme black holes, we study such spaces when the vector fie…
