Codimension one subgroups and boundaries of hyperbolic groups
Thomas Delzant, Panos Papasoglu
We construct hyperbolic groups with the following properties: The boundary of the group has big dimension, it is separated by a Cantor set and the group does not split. This shows…
Homomorphic images of Branch groups, and Serre's property (FA)
Thomas Delzant, Rostislav Grigorchuk
It is shown that a finitely generated branch group has Serre's property (FA) if and only if it does not surject onto the infinite cyclic group or the infinite dihedral group. An ex…
Well displacing representations and orbit maps
Thomas Delzant, Olivier Guichard, François Labourie +1
We discuss in this article a property of action of groups by isometries called "well displacing". An action is said to be well displacing, if the displacement function is equivalen…
Trees, valuations and the Green-Lazrsfeld set
Thomas Delzant
The aim of this paper is the study of the relationship between two objects, the Green-Lazarsfeld set and the Bieri Neumann Strebel invariant.
