On five-dimensional non-extremal charged black holes and FRW cosmology

Understand

We consider static non-extremal charged black hole solutions in the context of N=2 gauged supergravity theories in five dimensions, and we show that they satisfy first-order flow equations.

• Then we analyze the motion of the dual brane in these black hole backgrounds.
• We express the entropy in terms of a Cardy-Verlinde-type formula, and we show that the equations describing the FRW cosmology on the brane have a form that is similar to the equations for the entropy and for the Casimir energy on the brane.
• We also briefly comment on the inclusion of a Gauss-Bonnet term in the analysis.
