A bound for the number of automorphisms of an arithmetic Riemann surface

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/67711We show that for every g > 1 there is a compact arithmetic Riemann surface of genus g with at least 4(g-1) automorphisms, and that this lower bound is attained by infinitely many genera, the smallest being 24.11 pages, to appear in Math.
