On property (T) for automorphism groups of graph products
Nils Leder, Olga Varghese
We show that the automorphism group of a graph product of finite groups has Kazhdan's property (T) if and only if is a complete graph.

A note on locally elliptic actions on cube complexes
Nils Leder, Olga Varghese
We deduce from Sageev's results that whenever a group acts locally elliptically on a finite dimensional CAT(0) cube complex, then it must fix a point. As an application, we give an…

Serre's Property FA for automorphism groups of free products
Nils Leder
We study the automorphism group Aut(G) of a free product G of finite cyclic groups. We investigate the question in which cases Aut(G) has Serre's property FA. In the case of two or…
