Cosmology with Branes Wrapping Curved Internal Manifolds

In this paper we first derive solutions which can be interpreted as braneswrapping nontrivial curved manifolds, and then study their cosmologicalimplications. We find that at early times the branes tend to shrink theinternal manifold, while allowing the ``unwrapped'' dimensions to expand incongruence with what has already been observed in the case when the internalmanifold is flat (tori). However, at late times the internal curvature termsbecome important leading to potentially interesting differences.Comment: Minor changes, the journal version, a few references adde
