Fresh inflation from five-dimensional vacuum state

Abstract

I study fresh inflation from a five-dimensional vacuum state, where the fifth dimension is constant. In this framework, the universe can be seen as inflating in a four-dimensional FRW metric embedding in a five-dimensional metric. Finally, the experimental data $n_s=1$ are consistent with $(p+{\rho }_t)/{\rho }_t\simeq 1/3$ in the fresh inflationary scenario.
