On braneworld cosmologies from six dimensions, and absence thereof
arXiv:hep-th/0506035 · doi:10.1016/j.physletb.2005.11.064
Abstract
We consider (thin) braneworlds with conical singularities in six-dimensional Einstein-Gauss-Bonnet gravity with a bulk cosmological constant. The Gauss-Bonnet term is necessary in six dimensions for including non-trivial brane matter. We show that this model for axially symmetric bulks does not possess isotropic braneworld cosmological solutions.
