Scientific paper

We consider the dynamics of moduli fields in brane gas cosmology. By calculating the effective potentials from brane gas and bulk RR field, we found an attractor behavior that can fix both the radion and the dilaton. The potentials for radion and dilaton show global minima that can provide the stabilizing forces so that they can be stabilized dynamically. The effective potential for the three-dimensional volume is runaway-type so that it can inflate.
