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]…
