abstract = {In this note we consider the notion of rate of vanishing of the simple connectivity at infinity, a (growth) function that estimates metrically the topology at infinity of metric spaces. In particular we provide a different (geometric) proof of the linearity of the sci-growth for hyperbolic groups.}
