Spacetime symmetries and topology in bimetric relativity
Francesco Torsello, Mikica Kocic, Marcus Högås +1
We explore spacetime symmetries and topologies of the two metric sectors in Hassan-Rosen bimetric theory. We show that, in vacuum, the two sectors can either share or have separate…
On Birkhoff's theorem in ghost-free bimetric theory
Mikica Kocic, Marcus Högås, Francesco Torsello +1
We consider the Hassan-Rosen bimetric field equations in vacuum when the two metrics share a single common null direction in a spherically symmetric configuration. By solving these…
Algebraic Properties of Einstein Solutions in Ghost-Free Bimetric Theory
Mikica Kocic, Marcus Högås, Francesco Torsello +1
A known fact is that an Einstein solution in one sector in ghost-free bimetric theory implies an Einstein solution in the other sector. Earlier studies have also shown that some cl…
On the local structure of spacetime in ghost-free bimetric theory and massive gravity
S. F. Hassan, Mikica Kocic
The ghost-free bimetric theory describes interactions of gravity with another spin-2 field in terms of two Lorentzian metrics. However, if the two metrics do not admit compatible n…
Classification and asymptotic structure of black holes in bimetric theory
Francesco Torsello, Mikica Kocic, Edvard Mortsell
We study general properties of static and spherically symmetric bidiagonal black holes in Hassan-Rosen bimetric theory. In particular, we explore the behaviour of the black hole so…
