Randall-Sundrum versus holographic cosmology

We consider a model of a holographic braneworld universe in which a cosmological fluid occupies a 3 + 1-dimensional brane located at the boundary of the asymptotic anti-de Sitter bulk. We combine the AdS/CFT correspondence and the second Randall-Sundrum (RSII) model to establish a relationship between the RSII braneworld cosmology and the boundary metric induced by the time dependent bulk geometry. In the framework of the Friedmann-Robertson-Walker cosmology, we discuss some physically interesting scenarios involving the RSII and holographic braneworlds.
