Abstract: | Let (X,d) be a Gromov hyperbolic metric space, and let ∂X be the Gromov boundary of X. Fix a group G≤Isom(X) and a point ξ∈∂X. We consider the Diophantine approximation of a point η∈∂X by points in the set G(ξ). Our results generalize the work of many authors, in particular Patterson ('76) who proved most of our results in the case that G is a geometrically finite Fuchsian group of the first kind and ξ is a parabolic fixed point of G. |
