Quasi-isometric Co-hopficity of Non-uniform Lattices in Rank-one Semi-simple Lie Groups

چکیده
We prove that if G is a non-uniform lattice in a rank-one semisimple Lie group = Isom(H2 R ), then G is quasi-isometrically co-Hopf. This means that every quasi-isometric embedding G → G is coarsely surjective and thus is a quasi-isometry.

Let G and G be simple Lie groups of equal real rank and real rank at least 2. Let Γ < G and Λ < G be non-uniform lattices. We prove a theorem that often implies that any quasi-isometric embedding of Γ into Λ is at bounded distance from a homomorphism. For example, any quasiisometric embedding of SL(n,Z) into SL(n,Z[i]) is at bounded distance from a homomorphism. We also include a discussion of ...
متن کاملMOSTOW - MARGULIS RIGIDITY WITH LOCALLY COMPACT TARGETS 3 Construction
Let ? be a lattice in a simple higher rank Lie group G. We describe all locally compact (not necessarily Lie) groups H in which ? can be embedded as a lattice. For lattices ? in rank one groups G (with the only exception of non-uniform lattices in G ' SL 2 (R), which are virtually free groups) we give a similar description of all possible locally compact groups H, in which ? can be embedded as ...

We show that S-arithmetic lattices in semisimple Lie groups with no rank one factors are quasi-isometrically rigid.
متن کاملQuasi-isometries of rank one S-arithmetic lattices
We complete the quasi-isometric classification of irreducible lattices in semisimple Lie groups over nondiscrete locally compact fields of characteristic zero by showing that any quasi-isometry of a rank one S-arithmetic lattice in a semisimple Lie group over nondiscrete locally compact fields of characteristic zero is a finite distance in the sup-norm from a commensurator.
متن کاملSome Remarks on the co-volume of Lattices Acting on a Product of Trees
Many of the works concerning the automorphism group of a regular tree Aut(T ) and its uniform lattices suggest a strong resemblance between Aut(T ) and simple rank one real Lie groups, and even more so between Aut(T ) and the p-adic points of a rank one algebraic group G. Under this analogy the automorphism group of a product of two trees A = Aut(T n × T) = Aut(∆) corresponds to a product of tw...
