String Theory seminar - Perseas Christodoulidis Seminar

Abstract: Recent years have seen the introduction of various multi-field inflationary scenarios in which the curvature and geodesics of the scalar manifold play a crucial role. I will outline a simple description that unifies these different proposals and discuss their stability criteria. It will be shown that the underlying dynamics is governed by an effective potential, whose critical points and bifurcations determine the late-time behaviour of the system, thus unifying all different models of this type in the literature. I will also comment on the domain walls analogue of these solutions.
