Twisted Patterson-Sullivan measures and applications to amenability and coverings
Rémi Coulon, Rhiannon Dougall, Barbara Schapira +1
Let be two discrete groups acting properly by isometries on a Gromov-hyperbolic space . We prove that their critical exponents coincide if and only if is co-amenable…

Infinite periodic groups of even exponents
Rémi Coulon
We give a new proof that free Burnside groups of sufficiently large even exponents are infinite. The method is very flexible and can also be used to study (partially) periodic quot…

A non-residually finite group acting uniformly properly on a hyperbolic space
Rémi Coulon, Denis Osin
In this article we produce an example of a non-residually finite group which admits a uniformly proper action on a Gromov hyperbolic space.
