N2 - We consider the magnitude of string corrections to Einstein's equations to first order in the inverse string tension α′ and their importance at the "limiting" temperature implied by the exponential mass spectrum. In particular we consider both four- and ten-dimensional superstring theories with and without the inclusion of dilaton effects and the role of compactification. Cosmological applications such as inflation are also discussed. We find that a period of inflation necessarily requires a non-trivial role for the dilaton field.
