    Abstract

    We construct 4-dimensional cosmological FRW--models by compactifying a black 5-brane solution of type IIB supergravity, which carries both magnetic NS-NS-charge and RR-charge. The influence of nontrivial RR-fields on the dynamics of the cosmological models is investigated.Comment: 15 pages, LaTeX, psfig.sty, 5 figures. References added, version to appear in Phys.Lett.
