On asymptotic dimension of groups
We prove a version of the countable union theorem for asymptotic dimension and we apply it to groups acting on asymptotically finite dimensional metric spaces. As a consequence we obtain the following finite dimensionality theorems. A) An amalgamated product of asymptotically finite dimensional groups has finite asymptotic dimension: asdimA ∗C B <∞. B) Suppose that G′ is an HNN extension of a g...
متن کاملDimension of Asymptotic Cones of Lie Groups
We compute the covering dimension the asymptotic cone of a connected Lie group. For simply connected solvable Lie groups, this is the codimension of the exponential radical. As an application of the proof, we give a characterization of connected Lie groups that quasi-isometrically embed into a non-positively curved metric space.
متن کاملAsymptotic Dimension of Finitely Presented Groups
We prove that if a finitely presented group is one-ended then its asymptotic dimension is bigger than 1. It follows that a finitely presented group of asymptotic dimension 1 is virtually free.
متن کاملOn Asymptotic Dimension of Countable Abelian Groups
We compute the asymptotic dimension of the rationals given with an invariant proper metric. Also we show that a countable torsion abelian group taken with an invariant proper metric has asymptotic dimension zero.
متن کاملAsymptotic Dimension of Relatively Hyperbolic Groups
Suppose that a finitely generated group G is hyperbolic relative to a collection of subgroups {H1, . . . ,Hm}. We prove that if each of the subgroups H1, . . . ,Hm has finite asymptotic dimension, then asymptotic dimension of G is also finite.
