Lensed Density Perturbations in Braneworlds: An Alternative to Perturbations from Inflation
We consider a scenario in which our observable universe is a 3-dimensional surface (3-brane) living in extra dimensions with a warped geometry. We show that ``lensed'' density perturbations from other branes serve as possible seeds for structure formation on our observable brane (without i...
