Morse lemma for quasi-geodesics
= Morse lemma for quasi-geodesics
{c}
In a Gromov-hyperbolic geodesic metric space, every quasigeodesic segment stays within a uniformly bounded Hausdorff distance of a geodesic segment with the same endpoints. The bound depends only on the hyperbolicity and quasigeodesic constants.
The bounded-distance conclusion is a property of a <Gromov-hyperbolic metric space>, under the geodesic and quasigeodesic hypotheses stated here.
