Linearized gravity on branes: from Newton's law to cosmological perturbations

Abstract

We review here how Newton's law can be approximately recovered in the simple, "paradigmatic", case of a flat Z2-symmetric brane in a 5-D anti-de Sitter bulk. We then comment on the difficulties encountered so far in extending this analysis to cosmological perturbations on a Robertson-Walker brane.
