Failure of quasi-isometric rigidity for infinite-ended groups
Nir Lazarovich, Emily Stark
We prove that an infinite-ended group whose one-ended factors have finite-index subgroups and are in a family of groups with a nonzero multiplicative invariant is not quasi-isometr…

Commensurated hyperbolic subgroups
Nir Lazarovich, Alex Margolis, Mahan Mj
We show that if H is a non-elementary hyperbolic commensurated subgroup of infinite index in a hyperbolic group G, then H is virtually a free product of hyperbolic surface groups a…

Finite index rigidity of hyperbolic groups
Nir Lazarovich
We prove that the topological complexity of a finite index subgroup of a hyperbolic group is linear in its index. This follows from a more general result relating the size of the q…
