Large-scale cosmological perturbations on the brane
David Langlois, Roy Maartens, Misao Sasaki +1
In brane-world cosmologies of Randall-Sundrum type, we show that evolution of large-scale curvature perturbations may be determined on the brane, without solving the bulk perturbat…
Cosmic vorticity on the brane
Helen A. Bridgman, Karim A. Malik, David Wands
We study vector perturbations about four-dimensional brane-world cosmologies embedded in a five-dimensional vacuum bulk. Even in the absence of matter perturbations, vector perturb…
Dilaton-gravity on the brane
Kei-ichi Maeda, David Wands
We derive the four-dimensional field equations for the induced metric and scalar field on the world-volume of a 3-brane in a five-dimensional bulk with Einstein gravity plus a self…
Gravitational waves from inflation on the brane
David Langlois, Roy Maartens, David Wands
We discuss the evolution of gravitational waves in a brane-world cosmology embedded in five-dimensional anti-de Sitter spacetime. We show that during slow-roll inflation, modelled…
Cosmological perturbation spectra from SL(4,R)-invariant effective actions
Helen A. Bridgman, David Wands
We investigate four-dimensional cosmological vacuum solutions derived from an effective action invariant under global SL(n,R) transformations. We find the general solutions for lin…
