Subgroup growth of virtually cyclic right-angled Coxeter groups and their free products

Hyungryul Baik, Bram Petri, Jean Raimbault

We determine the asymptotic number of index $n$ subgroups in virtually cyclic right-angled Coxeter groups and their free products as $n \to \infty$ .

Subgroup growth of right-angled Artin and Coxeter groups

Hyungryul Baik, Bram Petri, Jean Raimbault

We determine the factorial growth rate of the number of finite index subgroups of right-angled Artin groups as a function of the index. This turns out to depend solely on the indep…
