Static vacuum metrics in (4 + 1) dimensions with Λ < 0 and squashed conformal infinity
Piotr T. Chruściel, 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…

Positivity of holographic energy
Piotr T. Chruściel, Raphaela Wutte
We prove positivity of a weighted holographic energy for four-dimensional spacetimes with negative cosmological constant whose conformal boundary at infinity is conformally static…

Holographic is Hamiltonian, relatively
Piotr T. Chruściel, Raphaela Wutte
We show that a relative holographic energy coincides with the relative Hamiltonian energy.
