Abstract
We study the effect of the solitonic degrees of freedom in string cosm ology following the line of Rama. The gas of a solitonic p-brane is tr eated as a perfect fluid in a Brans-Dicke-type theory. In this paper, ne find exact cosmological solutions for any Brans-Dicke parameter ome ga and for a general parameter gamma of the equation of state and clas sify the cosmology of the solutions on a parameter space of gamma and omega.
