Description

The brane-world cosmological model in higher-dimensional spacetime with a bulk scalar field is investigated. We derive the (4+n)-dimensional gravitational field equations for the scalar field on the (3+n)-brane in a (5+n)-dimensional bulk with Einstein gravity plus a self-interacting scalar field. The (4+n)-dimensional gravitational field equations can be formulated to standard form with the extra component. Using this formalism we study the Kaluza-Klein brane cosmology. We derive the Friedmann equation and a possible energy leak out of the brane into the bulk. We present some exact solutions corresponding to vacuum brane and matter on the brane.
