String Kaluza-Klein cosmologies with RR-fields

高能物理 - 理论 2009-10-30 v2

摘要

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.
