We prove some general results about quasi-actions on trees and define Property (QFA), which is analogous to Serre's Property (FA), but in the coarse setting. This property is shown to hold for a class of groups, including SL(n, Z) for n ≥ 3. We also give a way of thinking about Property (QFA) by breaking it down into statements about particular classes of trees. 
Constructing group actions on quasi-trees and applications to mapping class groups
A quasi-tree is a geodesic metric space quasi-isometric to a tree. We give a general construction of many actions of groups on quasi-trees. The groups we can handle include non-elementaryExpand
Bushy pseudocharacters and group actions on quasitrees
Given a group acting on a graph quasi-isometric to a tree, we give sufficent conditions for a pseudocharacter to be bushy. We relate this with the conditions studied by M. Bestvina and K. Fujiwara onExpand

Groups acting purely loxodromically on products of hyperbolic graphs
We consider the class of countable groups possessing an action on a finite product of hyperbolic graphs where every infinite order element acts loxodromically. When the graphs are locally finite, weExpand

Proper cocycles for uniformly bounded representations on subspaces of $L^1$
We show that if a countable group acts properly and isometrically on a finite product of quasi-trees, then it admits a proper 1-cocycle for a uniformly bounded representation on a subspace of an LExpand
Hyperbolic structures on wreath products
The study of the poset of hyperbolic structures on a group $G$ was initiated in a paper by C.Abbott, S.Balasubramanya and D.Osin. However, this poset is still very far from being understood andExpand
Property (QT) of 3-manifold groups
Introduced by Bestvina-Bromberg-Fujiwara, a finitely generated group is said to have property (QT) if it acts isometrically on a finite product of quasi-trees so that orbital maps are quasi-isometricExpand
Rank-One Isometries of Buildings and Quasi-Morphisms of Kac–Moody Groups
Given an irreducible non-spherical non-affine (possibly non-proper) building X, we give sufficient conditions for a group G < Aut(X) to admit an infinite-dimensional space of non-trivialExpand

Cocycle superrigidity and bounded cohomology for negatively curved spaces
We introduce new techniques to extend superrigidity theory beyond the scope of Lie or algebraic groups. We construct a cohomological invariant which accounts for, and generalizes, all knownExpand
Geometry of pseudocharacters
If G is a group, a pseudocharacter f : G → R is a function which is “almost” a homomorphism. If G admits a nontrivial pseudocharacter f, we define the space of ends of G relative to f and show thatExpand
