Late time evolution of brane gas cosmology and compact internal dimensions
arXiv:hep-th/0403096 · doi:10.1103/PhysRevD.70.104024
Abstract
We study the late-time behavior of a universe in the framework of brane gas cosmology. We investigate the evolution of a universe with a gas of supergravity particles and a gas of branes. Considering the case when different dimensions are anisotropically wrapped by various branes, we have derived Friedman-like equations governing the dynamics of wrapped and unwrapped subvolumes. We point out that the compact internal dimensions are wrapped by three or higher dimensional branes.
