Cosmology with density dependant moduli

By Malcolm Fairbairn, Université Libre de Bruxelles

We describe some aspects of cosmology in higher dimensional theories where the size of the compact dimensions depend upon the local value of the energy density. First we describe how cosmic acceleration can be obtained in such a model and constrain the ammount of this acceleration. Secondly we comment on how the relationship between different types of stress energy may be affected in such models.
