Abstract
In this paper we study the relationship between the homology and homotopy of a space at infinity and at its boundary. Firstly, we prove that if a locally connected, connected, -hyperbolic space that is acted upon geometrically by a group has trivial homotopy at infinity then the first \v{C}ech homotopy group is trivial. Secondly, we prove that if a hyperbolic group on a finite field has trivial homology at infinity then the boundary of the group has trivial Steenrod homology. This result turns out to be important in addressing an open problem related to Cannon's conjecture.
