Two remarks on near-horizon geometries

Research output: Contribution to journalArticlepeer-review


We show that any extreme black hole with an orthogonally transitive abelian isometry group has a near-horizon geometry with enhanced symmetry. We also point out a simple proof of the horizon topology theorem of Galloway and Schoen for degenerate horizons.
