The Inflationary Energy Scale in Braneworld Cosmology
Rachael M. Hawkins, James E. Lidsey
Upper bounds on the energy scale at the end of inflation in the Randall-Sundrum type II braneworld scenario are derived. The analysis is made exact by introducing new parameters th…

The Ermakov-Pinney Equation in Scalar Field Cosmologies
Rachael M. Hawkins, James E. Lidsey
It is shown that the dynamics of cosmologies sourced by a mixture of perfect fluids and self-interacting scalar fields are described by the non-linear, Ermakov-Pinney equation. The…

Inflation on a single brane - exact solutions
Rachael M. Hawkins, James E. Lidsey
Algorithms are developed for generating a class of exact braneworld cosmologies, where a self-interacting scalar field is confined to a positive-tension brane embedded in a bulk co…
