Gravitational instantons with symmetry

Steffen Aksteiner, Lars Andersson, Mattias Dahl +2

Uniqueness results for asymptotically locally flat and asymptotically flat -symmetric gravitational instantons are proved using a divergence identity of the type used in uniqu…

Vacuum initial data on from Killing vectors

Robert Beig, Piotr Bizoń, Walter Simon

We construct compact initial data of constant mean curvature for Einstein's 4d vacuum equations with positive, where is the…

Characterization of (asymptotically) Kerr-de Sitter-like spacetimes at null infinity

Marc Mars, Tim-Torben Paetz, José M. M. Senovilla +1

We investigate solutions to Einstein's vacuum field equations with positive cosmological constant which admit a smooth past null infinity à l…

Initial data for rotating cosmologies

Piotr Bizoń, Stefan Pletka, Walter Simon

We revisit the construction of maximal initial data on compact manifolds in vacuum with positive cosmological constant via the conformal method. We discuss, extend and apply recent…

The area-angular momentum inequality for black holes in cosmological spacetimes

Maria Eugenia Gabach Clement, Martin Reiris, Walter Simon

For a stable marginally outer trapped surface (MOTS) in an axially symmetric spacetime with cosmological constant and with matter satisfying the dominant energy condition, w…

Self-gravitating Newtonian disks revisited

Patryk Mach, Edward Malec, Walter Simon

Recent analytic results concerning stationary, self-gravitating fluids in Newtonian theory are discussed. We give a theorem that forbids infinitely extended fluids, depending on th…
