Groups with no coarse embeddings into hyperbolic groups
We introduce an obstruction to the existence of a coarse embedding of a given group or space into a hyperbolic group, or more generally into a hyperbolic graph of bounded degree. The condition we consider is “admitting exponentially many fat bigons”, and it is pre- served by a coarse embedding betwe...
