Abstract: In this expository talk, we present a theorem due to Fr´ed´eric Paulin which states that a hyperbolic group with infinite outer automorphism group acts non- trivially on anR-tree. In particular, the outer automorphism group of a hyperbolic group with Kazhdan’s property (T) is finite.

We give an example of a pure group that does not have the independence property, whose Fitting subgroup is neither nilpotent nor definable and whose soluble radical is neither
In this expository note, we present a result due to Frédéric Paulin which implies that a finitely generated hyperbolic group with Kazhdan’s property (T) has finite outer
This involves the interplay between the large scale geometry of relatively hyper- bolic groups and analytic properties of their boundaries.. We apply this to study the same question
Abstract: I will discuss an infinite group of geometric origin very much related to the symmetric group, in a way which is somewhat similar to the braid group. The group (and
