Unconventional cosmology on the (thick) brane
Ignacio Navarro, Jose Santiago
We consider the cosmology of a thick codimension 1 brane. We obtain the matching conditions leading to the cosmological evolution equations and show that when one includes matter w…
Compactifications of conformal gravity
Ignacio Navarro, Karel Van Acoleyen
We study conformal theories of gravity, i.e. those whose action is invariant under the local transformation g_{μν} -> ω^2 (x) g_{μν}. As is well known, in order to obtain Einstein…
Gravity on codimension 2 brane worlds
Ignacio Navarro, Jose Santiago
We compute the matching conditions for a general thick codimension 2 brane, a necessary previous step towards the investigation of gravitational phenomena in codimension 2 branewor…
Higher codimension braneworlds from intersecting branes
Ignacio Navarro, Jose Santiago
We study the matching conditions of intersecting brane worlds in Lovelock gravity in arbitrary dimension. We show that intersecting various codimension 1 and/or codimension 2 brane…
Einstein gravity on the codimension 2 brane?
Paul Bostock, Ruth Gregory, Ignacio Navarro +1
We look at general braneworlds in six-dimensional Einstein-Gauss-Bonnet gravity. We find the general matching conditions for the Einstein-Gauss-Bonnet braneworld, which remarkably…
Spheres, Deficit Angles and the Cosmological Constant
Ignacio Navarro
We consider compactifications of six dimensional gravity in four dimensional Minkowski or de Sitter space times a two dimensional sphere, S^2. As has been recently pointed out, it…
