Brane‐bulk matter relations for a purely conical codimension‐2 brane world Available to Purchase

We study gravity on an infinitely thin codimension‐2 brane world, with purely conical singularities and in the presence of an induced gravity term on the brane. We show that in this approximation, the energy momentum tensor of the bulk is strongly related to the energy momentum tensor of the brane and thus the gravity dynamics on the brane are induced by the bulk content. We show how this strong result is relaxed after including a Gauss‐Bonnet term in the bulk.
