Query: Compactification of IIB Theory with Fluxes and Axion-Dilaton String
  Cosmology   Compactification of type IIB theory on torus, in the presence of fluxes, is
considered. The reduced effective action is expressed in manifestly S-duality
invariant form. Cosmological solutions of the model are discussed in several
cases in the Pre-Big Bang scenario.
