Commensurability and quasi-isometric classification of hyperbolic surface group amalgams
Let CS denote the class of groups isomorphic to the fundamental group of two closed hyperbolic surfaces identified along an essential simple closed curve in each. We construct a bi-Lipschitz map between the universal covers of these spaces equipped with a CAT(−1) metric, proving all groups in CS are quasi-isometric. The class CS has infinitely many abstract commensurability classes, which we ch...
متن کاملGroups quasi-isometric to H² x R
The most powerful geometric tools are those of differential geometry, but to apply such techniques to finitely generated groups seems hopeless at first glance since the natural metric on a finitely generated group is discrete. However Gromov recognized that a group can metrically resemble a manifold in such a way that geometric results about that manifold carry over to the group [18, 20]. This ...
متن کاملGroups Quasi-isometric to Complex Hyperbolic Space
We show that any finitely generated group quasi-isometric to complex hyperbolic space is a finite extension of a properly discontinuous, cocompact subgroup of the isometry group.
متن کاملQuasi-isometric rigidity of solvable groups
In this article we survey recent progress on quasi-isometric rigidity of polycyclic groups. These results are contributions to Gromov’s program for classifying finitely generated groups up to quasi-isometry [Gr2]. The results discussed here rely on a new technique for studying quasi-isometries of finitely generated groups, which we refer to as coarse differentiation. We include a discussion of ...
متن کاملQuasi-isometric Classification of Graph Manifolds Groups
We show that the fundamental groups of any two closed irreducible non-geometric graph-manifolds are quasi-isometric. This answers a question of Kapovich and Leeb. We also classify the quasi-isometry types of fundamental groups of graph-manifolds with boundary in terms of certain finite two-colored graphs. A corollary is a quasi-isometry classification of Artin groups whose presentation graphs a...
