Toric gravitational instantons with four fixed points
Lars Andersson, Mattias Dahl, Gustav Nilsson
We classify the simply connected toric gravitational instantons whose torus action has four fixed points. They are the hyperkähler multi-Eguchi--Hanson and multi-Taub--NUT metrics…
On the Geroch conjecture for toric gravitational instantons
Lars Andersson, Mattias Dahl, Gustav Nilsson
Geroch conjectured that the local solutions of the vacuum Einstein equations with two commuting Killing fields and vanishing twist constants are generated from flat space by an inf…
Mode Stability for Gravitational Instantons of Type D
Gustav Nilsson
We study Ricci-flat perturbations of gravitational instantons of Petrov type D. Analogously to the Lorentzian case, the Weyl curvature scalars of extreme spin-weight satisfy a Riem…
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…
