Asymptotia of Kerr-de Sitter Black Holes
Samuel Blitz, Jarosław Kopiński
Exterior geometries of physical black holes are believed to asymptotically approach the Kerr--de Sitter spacetime at late times. A characteristic feature of that vacuum Einstein so…

Boundary Curvature Scalars on Conformally Compact Manifolds
A. Rod Gover, Jarosław Kopiński, Andrew Waldron
We introduce a sequence of conformally invariant scalar curvature quantities, defined along the conformal infinity of a conformally compact (CC) manifold, that measure the failure…
