| Abstract | For i D 1; 2, let Gi be cocompact groups of isometries of hyperbolic space H of real dimension n, n 3. LetHi Gi be infinite index quasiconvex subgroups satisfying one of the following conditions: (1) The limit set of Hi is a codimension one topological sphere. (2) The limit set of Hi is an even dimensional topological sphere. (3) Hi is a codimension one duality group. This generalizes (1). In particular, if n D 3, Hi could be any freely indecomposable subgroup of Gi . (4) Hi is an odd-dimensional Poincaré duality group PD.2k C 1/. This generalizes (2). We prove pattern rigidity for such pairs extending work of Schwartz who proved pattern rigidity whenHi is cyclic. All this generalizes to quasiconvex subgroups of uniform lattices in rank one symmetric spaces satisfying one of the conditions (1)–(4), as well as certain special subgroups with disconnected limit sets. In particular, pattern rigidity holds for all quasiconvex subgroups of hyperbolic 3-manifolds that are not virtually free. Combining this with results of Mosher, Sageev, and Whyte, we obtain quasi-isometric rigidity results for graphs of groups where the vertex groups are uniform lattices in rank one symmetric spaces and the edge groups are of any of the above types.
