Quasi-isometry invariant commensurizer subgroups

I will present results about the quasi-isometry invariance of the existence and location of certain infinite cyclic subgroups and their commensurizers in one-ended finitely presented groups. An application of this is the quasi-isometry invariance of certain vertex groups of the Scott-Swarup JSJ decomposition for groups.
