Abstract

If a Hausdorff locally compact paracompact space has a coarse structure, then there is a family of well behaved compactifications associated to it. If there are two of these spaces, XX and YY, with a good coarse equivalence, then there is a correspondence between these families of compactifications of XX and YY. On the other hand, if a group GG has a properly discontinuous cocompact action on a Hausdorff locally space XX, then there is also a correspondence between nice compactifications of GG and nice compactifications of XX. In this paper we show that when there are both concepts involved (coarse structure and group action), then both correspondences of families of compactifications agree. We also prove that these correspondences must preserve some geometric properties of the compactifications.
