dc.description.abstractIf the fundamental building blocks of matter are elementary superstrings instead of point particles, the evolution of the very early Universe will be very different than in standard big bang cosmology. String gas cosmology is based on making use of key new degrees of freedom and symmetries which distinguish string theories from point particle theories. After deriving the general equations of motion for particle geodesics, the case is specialized for a cosmological background with vanishing antisymmetric tensor field. Following these prescriptions, the paper shows the existence of a singularity-free cosmological solution.en
