The Median Class and Superrigidity of Actions on CAT(0) Cube Complexes
Indira Chatterji, Talia Fernós, Alessandra Iozzi
We define a bounded cohomology class, called the {\em median class}, in the second bounded cohomology -- with appropriate coefficients --of the automorphism group of a finite dimen…
Isometric properties of relative bounded cohomology
Michelle Bucher, Marc Burger, Roberto Frigerio +3
We show that the isomorphism induced by the inclusion of pairs between the relative bounded cohomology of and the bounded cohomology of is…
A Dual Interpretation of the Gromov--Thurston Proof of Mostow Rigidity and Volume Rigidity for Representations of Hyperbolic Lattices
Michelle Bucher, Marc Burger, Alessandra Iozzi
We use bounded cohomology to define a notion of volume of an SO(n,1)-valued representation of a lattice SO(n,1) and, using this tool, we give a complete proof of the volume rigidit…
Stability properties of multiplicative representations of free groups
Alessandra Iozzi, M. Gabriella Kuhn, Tim Steger
We extend the construction of multiplicative representations for a free group G introduced by Kuhn and Steger (Isr. J., (144) 2004) in such a way that the new class Mult(G) so defi…
