Examples of hyperlinear groups without factorization property
Andreas Thom
In this note we give an example of a group which is locally embeddable into finite groups (in particular it is initially subamenable, sofic and hence hyperlinear) but does not have…

Low degree bounded cohomology and l^2-invariants for negatively curved groups
Andreas Thom
We study the subgroup structure of discrete groups which share cohomological properties which resemble non-negative curvature. Examples include all Gromov hyperbolic groups. We pro…
