Abstract
We discuss cosmology in four dimensions within the context of a brane-world scenario. Such models can predict chaotic inflation with very low reheat temperature depending on the brane tension. We notice that the gravitino abundance is different in brane-world cosmology and by tuning the brane tension it is possible to get an extremely low abundance. We also study Affleck-Dine baryogenesis in our toy model.
