Self-accelerating Solutions in Massive Gravity on Isotropic Reference
Metric [PDF]
Hayato Motohashi, Teruaki SuyamaWithin the framework of recently proposed ghost-free massive gravity, cosmological constant type self-accelerating solution has been obtained for Minkowski and de Sitter reference metrics. We ease the assumption on the reference metric and find the self-accelerating solution for the reference metric respecting only isotropy, thus considerably extending the range of known solutions.View original: http://arxiv.org/abs/1208.3019
