Strong Jordan separation and applications to rigidity
J. -F. Lafont
We prove that simple, thick hyperbolic P-manifolds of dimension >2 exhibit Mostow rigidity. We also prove a quasi-isometry rigidity result for the fundamental groups of simple, thi…

EZ-structures and topological applications
F. T. Farrell, J. -F. Lafont
We introduce the notion of an EZ-structure on a group. Delta-hyperbolic groups and CAT(0)-groups have EZ-structures. We show torsion-free groups having an EZ-structure automaticall…
