Abstract
We consider a -dimensional cosmological model with a dilaton field and two -form field strengths which have nonvanishing fluxes in extra dimensions. Exact solutions for the model with a certain set of couplings are obtained by separation of three variables. Some of the solutions describe accelerating expansion of the -dimensional space. Quantum cosmological aspects of the model are also briefly mentioned.
