Bounded cohomology, cross ratios and cocycles
Ursula Hamenstaedt
We use cross ratios to describe second real continuous bounded cohomology for locally compact topological groups. We also derive a rigidity result for cocycles with values in the i…

Bounded cohomology and isometry groups of hyperbolic spaces
Ursula Hamenstaedt
Let X be an arbitrary hyperbolic geodesic metric space and let G be a countable non-elementary weakly acylindrical group of isometries of X. We show that the second bounded cohomol…

Train tracks and the Gromov boundary of the complex of curves
U. Hamenstaedt
We give a combinatorial proof of an unpublished result of E. Klarreich: The Gromov boundary of the complex of curves of a non-exceptional oriented surface S of finite type can natu…
