Abstract :
An action inspired on the low-energy effective action for heterotic string and Weyl integrable space-time theory is used to describe the radiation era in scalar-tensor cosmology. The resulting field equations for a Friedmann–Robertson–Walker geometry are written and the general solution for this system is obtained and its main properties are discussed.
