Static vacuum metrics in (4 + 1) dimensions with Î < 0 and squashed conformal infinity
Piotr T. ChruÅciel, Jiaxin Song, Raphaela Wutte +2
We construct numerically two families of static five-dimensional Lorentzian metrics, solutions of vacuum Einstein equations with a negative cosmological constant, one with and one…

Looking through the Kerr disk
Maciej Maliborski, Tobias C. Sutter
We study null geodesics that connect the two asymptotically flat regions of the maximally extended Kerr spacetime. These vortical geodesics traverse both horizons and pass through…

Multisoliton solutions for equivariant wave maps on a dimensional wormhole
Piotr BizoÅ, Jacek Jendrej, Maciej Maliborski
We study equivariant wave maps from the dimensional wormhole to the 2-sphere. This model has explicit harmonic map solutions which, in suitable coordinates, have the form of…
