Query: Inflationary slow-roll formalism and perturbations in the
  Randall-Sundrum Type II braneworld   We formalize the Hubble slow-roll formalism for inflationary dynamics in
Randall-Sundrum Type II braneworld cosmologies, defining Hubble slow-roll
parameters which can be used along with the Hamilton-Jacobi formalism.
Focussing on the high-energy limit, we use these to calculate the exact power
spectrum for power-law inflation, and then perturb around this solution to
derive the higher-order expression for the density perturbations (sometimes
called the Stewart-Lyth correction) of slow-roll braneworld models. Finally we
apply our result to specific examples of potentials to calculate the correction
to the amplitude of the power spectrum, and compare it with the standard
cosmology. We find that the amplitude is not changed significantly by the
higher-order correction.
