Baumslag-Solitar relations in abstract commensurators of free groups
Khalid Bou-Rabee, Samuel Young
Any non-residually finite Baumslag-Solitar group has a non-residually finite image in the abstract commensuration of a nonabelian free group. This gives a new proof (avoiding Britt…
Residual finiteness growths of Lamplighter groups
Khalid Bou-Rabee, Junjie Chen, Anastasiia Timashova
Residual finiteness growth gives an invariant that indicates how well-approximated a finitely generated group is by its finite quotients. We briefly survey the state of the subject…
Arbitrarily Large Residual Finiteness Growth
Khalid Bou-Rabee, Brandon Seward
The residual finiteness growth of a group quantifies how well approximated the group is by its finite quotients. In this paper, we construct groups with arbitrarily large residual…
Approximating a group by its solvable quotients
Khalid Bou-Rabee
The solvable Farb growth of a group quantifies how well-approximated the group is by its finite solvable quotients. In this note we present a new characterization of polycyclic gro…
