Non-conformally flat bulk spacetime and the 3-brane world
arXiv:hep-th/0104174 · doi:10.1016/S0370-2693(01)00679-7
Abstract
We show that for non-conformally flat bulk spacetime, there exist no bound modes for zero mass graviton on the 3-brane. The brane world model is therefore unstable for the bulk spacetime being different from the conformally flat anti - de Sitter space.
