Non-locality as an essential feature of brane worlds
Abstract
Weak gravity in the brane world scenario with a scalar field in the bulk between two end-of-the-world branes is investigated by using the doubly gauge invariant formalism. We review the result that Einstein gravity is restored in the low energy limit and that high-energy corrections to Einstein gravity can be mimicked by higher derivative terms. After that, it is argued that non-locality is one of essential features of brane worlds.
