Finitely generated groups acting uniformly properly on hyperbolic space
Robert Kropholler, Vladimir Vankov
We construct an uncountable sequence of groups acting uniformly properly on hyperbolic spaces. We show that only countably many of these groups can be virtually torsion-free. This…

Virtually special non-finitely presented groups via linear characters
Vladimir Vankov
We present a new method for showing that groups are virtually special. This is done by considering finite quotients and linear characters. We use this to show that an infinite fami…
