Title:  Quasi-isometry invariant commensurizer subgroups

Abstract:  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.
