Cosmic scenario with Einstein–Gauss–Bonnet gravity

By taking into account the Einstein–Gauss–Bonnet dilaton-coupled interaction in the background of the Robertson–Walker metric, we provide some bouncing solutions of the early universe from analytic solutions of the field equations for vanishing three space curvature. For a few potentials, the solutions involving the slow-roll-type approximation produce results that are very same to those of the early era’s bouncing solutions. Considering a different approach of slow-roll approximation, the universe goes through much faster initially than standard inflation, but at a later stage, the universe enters into standard exponential inflation.
