We investigate certain geometric characterizations of Gromov hyperbolicity for punctured metric spaces. We show that for such spaces, uniformity, annular quasiconvexity with respect to the punctured point, and Gromov hyperbolicity respecting the quasihyperbolic metric are mutually quantitatively equivalent. As an application, we obtain a sufficient and necessary condition for an interior point in a uniform metric space to be removable. © 2021...
