Asymptotically flat spacetimes in 3D bigravity
arXiv:1207.0882 · doi:10.1103/PhysRevD.86.084045
Abstract
We report that a class of three-dimensional bimetric theories contain asymptotically flat solutions. These spacetimes can be cast in a set of asymptotic conditions at null infinity which are preserved under the infinite dimensional BMS group. Moreover, the algebra of the canonical generators exhibits a central extension. The possibility that these solutions describe regular black holes is also discussed.
