We show that the boundary of a one-ended hyperbolic group that has enough codimension-1 surface subgroups and is simply connected at infinity is homeomorphic to a 2-sphere. Together with a result of Markovic, it follows that these groups are Kleinian groups.
In my talk, I will describe this result and give a sketch of the proof.
This is joint work with N. Lazarovich.
