Periodic Analogs of Multiple Black Holes Solutions
Omar E. Ortiz, Javier Peraza
In this article, we extend the numerical studies developed in [arXiv:2210.12898] to construct periodic stationary axisymmetric solutions containing multiple horizons in each fundam…
Periodic Kerr solution as an infinite soliton chain
Dmitry Korotkin, Javier Peraza
We combine numerical analysis with the inverse scattering method to study the periodic analog of Kerr solution. The periodic analog of the Schwarzschild solution is known to be reg…
Static vacuum 3+1 black holes that cannot be put into stationary rotation
Javier Peraza, Martin Reiris
We prove that some of the static Myers/Korotkin-Nicolai (MKN) vacuum 3+1 static black holes cannot be put into stationary rotation. Namely, they cannot be deformed into axisymmetri…
Periodic analogues of the Kerr solutions: a numerical study
Javier Peraza, Martín Reiris, Omar E. Ortiz
In recent years black hole configurations with non standard topology or with non-standard asymptotic have gained considerable attention. In this article we carry out numerical inve…
Generalized BMS charge algebra
Miguel Campiglia, Javier Peraza
It has been argued that the symmetries of gravity at null infinity should include a Diff factor associated to diffeomorphisms on the celestial sphere. However, the standard…
On the classical and quantum Geroch group
Javier Peraza, Miguel Paternain, Michael Reisenberger
The Geroch group is an infinite dimensional transitive group of symmetries of classical cylindrically symmetric gravitational waves which acts by non-canonical transformations on t…
A complete classification of S1-symmetric static vacuum black holes
Martín Reiris, Javier Peraza
In a seminal paper of 1917, H. Weyl presented a remarkable reduction of the static axisymmetric vacuum Einstein equations, serving as a relatively straightforward technique to gene…
