Abstract
We derive the 4D low energy effective field theory for a, closed string gas on a time dependent FRW background. We examine the solutions and find that although the Brandenberger-Vafa. mechanism at late times no longer leads to radion stabilization, the radion rolls slowly enough that the scenario is still of interest. In particular, we find a simple example of the string inspired dark matter recently proposed by Gubser and Peebles.
