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…

On abstract commensurators of surface groups

Khalid Bou-Rabee, Daniel Studenmund

Let be the fundamental group of a surface of finite type and Comm be its abstract commensurator. Then Comm contains the solvable Baumslag--Solitar groups $\langle a ,…

Commensurability growths of algebraic groups

Khalid Bou-Rabee, Tasho Kaletha, Daniel Studenmund

Fixing a subgroup in a group , the full commensurability growth function assigns to each the cardinality of the set of subgroups of with $[Γ: Γ\cap Δ][Δ: Γ\cap Δ…

Commensurability growth of branch groups

Khalid Bou-Rabee, Rachel Skipper, Daniel Studenmund

Fixing a subgroup in a group , the commensurability growth function assigns to each the cardinality of the set of subgroups of with $[Γ: Γ\cap Δ][Δ: Γ\cap Δ] = n…

Arithmetic lattices in unipotent algebraic groups

Khalid Bou-Rabee, Daniel Studenmund

Fixing an arithmetic lattice in an algebraic group , the commensurability growth function assigns to each the cardinality of the set of subgroups with $[Γ: Γ\cap Δ]…
