Cocycle superrigidity from higher rank lattices to $Out (F_{N})$

Vincent Guirardel, Camille Horbez, Jean Lécureux

We prove a rigidity result for cocycles from higher rank lattices to $Out (F_{N})$ and more generally to the outer automorphism group of a torsion-free hyperbolic group. More…

Combinatorial and group-theoretic compactifications of buildings

Pierre-Emmanuel Caprace, Jean Lecureux

Let X be a building of arbitrary type. A compactification $C_{r} (X)$ of the set Res(X) of spherical residues of X is introduced. We prove that it coincides with the horofunction comp…
