A bound for the number of automorphisms of an arithmetic Riemann surface
Abstract
Description
We 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.
