Abstract
Brane Gas Cosmology (BGC) is an M-theory motivated attempt to reconcile aspects of standard cosmology based on Einstein's theory of general relativity. The background in this framework is described by dilaton gravity, which introduces various moduli fields for the shape and size of the extra dimensions and the dilaton. Following previous successes in this field, we dimensionally reduce a gas of strings and branes to the d + 1-dimensional Einstein frame with the hopes of understanding late-time BGC. This procedure generates an effective potential for the moduli fields, which we analyze in the hopes of stabilizing all fields; however, with the inclusion of strings and branes alone we find one direction remains free to roll away.
