Abstract
Two equivalent metrics can be compared, with respect to their uniform properties, in several different ways. We present some of them, and then use one of these conditions to characterize which metrics on a space induce the same lower Hausdorff topology on the hyperspace. Finally, we focus our attention to complete metrics.
Key words and phrases.: Metrizable space; hyperspace; lower Hausdorff topology; Hausdorff metric topology; equivalent metrics; uniformly equivalent metrics; gap; totally bounded set; complete subspace; uniformly discrete set; wide family of sets
