| Abstract: | We compute the quasi-isometry group of an irreducible nonuniform lattice in a semisimple Lie group with finite center and no rank one factors, and show that any two such lattices are quasi-isometric if and only if they are commensurable up to conjugation. |
| Keywords: | Lie groups discrete subgroups geometric group theory |
