Coarse extrinsic geometry: a survey
This paper is a survey of some of the developments in coarse extrinsic geometry since its inception in the work of Gromov.Distortion, as measured by comparing the diameter of balls relative to different metrics, can be regarded as one of the simplist extrinsic notions.Results and examples concerning distorted subgroups, especially …
