Rank gradient and torsion groups
We construct first examples of infinite finitely generated residually finite torsion groups with positive rank gradient. In particular, these groups are non-amenable. Some applications to problems about cost and L-Betti numbers are discussed.
متن کاملKleinian groups of small Hausdorff dimension are classical Schottky groups
Let H be the hyperbolic 3-space. A subgroup Γ of PSL(2,C) = Iso(H) is called a Kleinian group if it is discrete. Let x ∈ H. The orbit of x under action of Γ is denoted by Γx. The limit set ΛΓ of Γ is definited as ΛΓ = Γx ∩ ∂H. By definition, ΛG is smallest closed Γ-invariant subset of ∂H. The group Γ is called second kind if ΛΓ 6= ∂H, otherwise it is said to be first kind. The set ΩΓ = ∂H 3 − Λ...
متن کاملPositive Operators and Hausdorff Dimension of Invariant Sets
In this paper we obtain theorems which give the Hausdorff dimension of the invariant set for a finite family of contraction mappings which are “infinitesimal similitudes” on a complete, perfect metric space. Our work generalizes the graph-directed construction of Mauldin and Williams (1988) and is related in its general setting to results of Schief (1996), but differs crucially in that the mapp...
متن کاملDimension and Rank for Mapping Class Groups
We study the large scale geometry of the mapping class group, MCG. Our main result is that for any asymptotic cone of MCG, the maximal dimension of locally compact subsets coincides with the maximal rank of free abelian subgroups of MCG. An application is a proof of Brock-Farb’s Rank Conjecture which asserts that MCG has quasi-flats of dimension N if and only if it has a rank N free abelian sub...
متن کاملAnalyticity of Hausdorff dimension of limit sets of Kleinian groups
We show that the Hausdorff dimension of the limit set is a real analytic function on the deformation space of a certain class of convex co-compact Kleinian groups, which includes all convex co-compact function groups. This extends a result of Ruelle [21] for quasifuchsian groups.
