Evolution of cosmological models in the brane-world scenario - art. no. 104012

In this work we consider Randall-Sundrum brane-world type scenarios, in whi ch the spacetime is described by a five-dimensional manifold with matter fi elds confined in a domain wall or three-brane. We present the results of a systematic analysis, using dynamical systems techniques, of the qualitative behavior of the Friedmann-Lemaitre-Robertson-Walker and the Bianchi type I and V cosmological models in these scenarios. We construct the state space s for these models and discuss how their structure changes with respect to the general-relativistic case, in particular, what new critical points appe ar and their nature, the occurrence of bifurcations and the dynamics of ani sotropy.
