Homogeneous anisotropic solutions of topologically massive gravity with cosmological constant and their homogeneous deformations
arXiv:1211.2581 · doi:10.1088/0264-9381/30/12/125014
Abstract
We solve the equations of topologically massive gravity with potentially non-vanishing cosmological constant for homogeneous metrics without isotropy. We only reproduce known solutions. We also discuss their homogeneous deformations, possibly with isotropy. We show that de Sitter space and hyperbolic space cannot be infinitesimally homogeneously deformed in TMG. We clarify some of their Segre-Petrov types and discuss the warped de Sitter spacetime.
