Mathematics and Applications of Branes in String and M-theory

We study models of multi-field inflation in which the inflationary trajectory contains a strong bending occurring when the observable scales are still inside the Hubble radius. We discuss the impact of such a fast-tirn feature on the dynamics of the inflationary perturbations – and the traces such an event may leave in the power spectrum of curvature perturbations.
