Local commensurability graphs of solvable groups
Khalid Bou-Rabee, Chen Shi
The commensurability index between two subgroups of a group is . This gives a notion of distance amongst finite-index subgroups of , whi…
Groups with near exponential residual finiteness growth
Khalid Bou-Rabee, Aglaia Myropolska
A function is near exponential if it is bounded above and below by functions of the form for some . In this article we develop tools to…
The topology of local commensurability graphs
Khalid Bou-Rabee, Daniel Studenmund
We initiate the study of the -local commensurability graph of a group, where is a prime. This graph has vertices consisting of all finite-index subgroups of a group, where a…
Weakly maximal subgroups in regular branch groups
Khalid Bou-Rabee, Paul-Henry Leemann, Tatiana Nagnibeda
Let be a finitely generated regular branch group acting by automorphisms on a regular rooted tree . It is well-known that stabilizers of infinite rays in (aka parabolic…
