Relative Hyperbolicity and Bounded Cohomology
Let Γ be a finitely generated group and Γ′ = {Γi | i ∈ I} be a family of its subgroups. We utilize the notion of tuple (Γ,Γ′, X,V ′) that makes the statements and arguments for the pair (Γ,Γ′) parallel to the non-relative case, and define the snake metric dς on the set of edges of a simplicial complex. The language of tuples and snake metrics seems to be convenient for dealing with relative hyp...
متن کاملB-Bounded Cohomology and Applications
A discrete group with word-length (G,L) is B -isocohomological for a bounding classes B if the comparison map from B -bounded cohomology to ordinary cohomology (with coefficients in C) is an isomorphism; it is strongly B isocohomological if the same is true with arbitrary coefficients. In this paper we establish some basic conditions guaranteeing strong B -isocohomologicality. In particular, we...
متن کاملOn Transfer in Bounded Cohomology
We define a transfer map in the setting of bounded cohomology with certain metric G-module coefficients. As an application, we extend a theorem on the comparison map from Borelbounded to Borel cohomology (cf. [1]), to cover the case of Lie groups with finitely many connected components.
متن کاملBounded Cohomology Characterizes Hyperbolic Groups
A finitely presentable group G is hyperbolic if and only if the map H2 b (G, V ) → H2(G, V ) is surjective for any bounded G-module. The ‘only if’ direction is known and here we prove the ‘if’ direction. We also consider several ways to define a linear homological isoperimetric inequality.
