Abstract :
We study bouncing and cyclic universes from an (n + 1)-dimensional brane in the (n + 2)dimensional charged AdS bulk background. In the moving domain wall (MDW) approach, this picture is clearly realized with a specified bulk configuration, the 5D charged topological AdS (CTAdS5) black hole with mass M and charge Q. The bulk gravitational dynamics induces the 4D Friedmann equations with CFT radiation and exotic stiff matter for a dynamic brane. This provides bouncing universes for k = 0, -1 and cyclic universe for k = 1, even though it has an exotic stiff matter from the charge Q. In this work we use the other Binetruy-Deffayet-Langlos (BDL) approach with the bulk Maxwell field. In this case, we are free to determine the corresponding mass M and charge Q because the mass term is usually included as an initial condition and the charge is given by an unspecified solution to the Maxwell equation under the BDL metric. Here we obtain only bouncing universes if one does not choose two CTAdS5 black holes as the bulk spacetime. We provide a way of avoiding the exotic matter on the brane by introducing an appropriate local matter. Finally, we discuss an important relation between the exotic holographic matter and Lorentz invariance violation.
