* Phenomenology: 2000,
Carroll showed that if the number of extra dimensions n 
2,
and with some model for matter (gauge field + cosmological constant), there
are no stable models; Expects this to be true more generally; 2003, Models
seem to have difficulties
producing a reasonable inflation.
* Models: Randall-Sundrum
models have an AdS bulk; Dvali-Gabadadze-Porrati (DGP) models have a flat bulk.

* Idea: A cosmological
scenario without an initial singularity, proposed in 2001 by Steinhardt,
Khoury, Turok and Ovrut; The hot big bang is produced in an
otherwise empty, static universe by
the
collision
of a brane in the bulk with a bounding orbifold plane; Claims to solve the
horizon, flatness and monopole problems and generate a nearly scale-invariant
spectrum of perturbations without the superluminal expansion of inflation.

* Idea: The extra dimensions
are compactified; The usual spacetime is a 4D hypersurface or brane, and the
bulk spacetime is Anti-de Sitter; Need a large < 0;
First model motivated by claims that it solves the hierarchy problem; Second
model, with hidden brane pushed to infinite distance, motivated by claims that
it reproduces Newtonian gravity.
