"WebJan 12, 2010 · The quantitative estimates used here are the Bishop theorems of §III.4. More generally, one may relax the degree of local uniformity and nevertheless obtain similar discretizations of Riemannian manifolds. Here, for the calibration of discrete to the continuous, one must use Gromov's refinement of the Bishop theorems (see §III.4). " - Finiteness theorems for riemannian manifolds
