Large radius Hagedorn regime in string gas cosmology

Large radius Hagedorn regime in string gas cosmology

We calculate the equation of state of a gas of strings at high density in a large toroidal universe and use it to determine the cosmological evolution of background metric and dilaton fields in the entire large radius Hagedorn regime, (lnS){sup 1/d}
