Add to ORKGWe describe a simple criterion for showing that a group has Serre's property FA. By exhibiting a certain pattern of finite subgroups, we show that this criterion is satisfied by Aut(F_n) and SL(n,Z) when n>=3
This thesis considers groups which act cocompactly on a product of two trees and draws on previous r...

Abstract. It is shown that a finitely generated branch group has Serre’s property (FA) if and only i...
We construct the first example of a finitely generated group which has Serre's property (FA) (i.e., ...
We establish three independent results on groups acting on trees. The first implies that a compactly...

We introduce the notion of the k-closure of a group of automorphisms of a locally finite tree, and g...
