Recent years have seen the introduction of various multi-field inflationary scenarios, in which the scalar curvature plays a crucial role. We outline a simple description that unifies these different proposals. Moreover, one can easily see which dynamical attractors will dominate the late-time behaviour of the system. We demonstrate which bifurcations govern the underlying dynamics.Non UBCUnreviewedAuthor affiliation: University of GroningenResearche
