Betti numbers of Shimura curves and arithmetic three--orbifolds
Mikołaj Frączyk, Jean Raimbault
We show that asymptotically the first Betti number, or the arithmetic genus, of a Shimura curve satisfies the Gauss--Bonnet equality. We also show that the first Betti number of a…
On distinct finite covers of 3-manifolds
Stefan Friedl, JungHwan Park, Bram Petri +2
Every closed orientable surface S has the following property: any two connected covers of S of the same degree are homeomorphic (as spaces). In this, paper we give a complete class…
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 subgroups in virtually cyclic right-angled Coxeter groups and their free products as .
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…
