Spherical and geodesic growth rates of right-angled Coxeter and Artin groups are Perron numbers

Alexander Kolpakov, Alexey Talambutsa

We prove that for any infinite right-angled Coxeter or Artin group, its spherical and geodesic growth rates (with respect to the standard generating set) either take values in the…
