Abstract
The inflationary attractor properties of the canonical scalar field and Born–Infeld field are investigated in the Randall–Sundrum II scenario with a Gauss–Bonnet term in the bulk action. We find that the inflationary attractor property will always hold for both the canonical and Born–Infeld fields for any allowed non-negative Gauss–Bonnet coupling. We also briefly discuss the possibility of explaining the suppressed lower multiples and running a scalar spectral index simultaneously in the scenario of Gauss–Bonnet brane inflation.
