Gravity Waves FromPrimordial Dimensional Reduction

We show that the dynamical contraction of n "internal" spacelike dimensions leads, in general, to the formation of a cosmic graviton background, similar to that produced by innation. By using a simple phenomenological model we discuss how to obtain information and constraints on the total number of extra dimensions, on their compactiication scale and on the kinematics of the dimensional reducti...

Gravitational Waves in a Codimension Two Braneworld

We consider the propagation of gravitational waves in six dimensions induced by sources living on 3-branes in the context of a recent exact solution [1]. The brane geometries are de Sitter and the bulk is a warped geometry supported by a positive cosmological constant as well as a 2-form flux. We show that at low energies ordinary gravity is reproduced, and explicitly compute the leading correc...

Braneworld Kaluza - Klein Reduction

We obtain new results for consistent braneworld Kaluza-Klein reductions, showing how we can derive four-dimensional N = 2 gauged supergravity " localised on the AdS 4 brane " as an exact embedding in five-dimensional N = 4 gauged supergravity. Similarly, we obtain five-dimensional N = 2 gauged supergravity localised on an AdS 5 brane as a consistent Kaluza-Klein reduction from six-dimensional N...
