In Riemann surface theory and hyperbolic geometry, a Hurwitz surface, named after Adolf Hurwitz, is a compact Riemann surface with precisely 84(g − 1) automorphisms, where g is the genus of the surface. This number is maximal by virtue of Hurwitz's theorem on automorphisms (Hurwitz … Meer weergeven Only finitely many Hurwitz surfaces occur with each genus.

The second thing may indeed have been investigated by Hurwitz (I don't know), and does indeed fit into a general understanding (e.g., see Weil's "Basic Number theory", or my … Webtranslation surfaces, for which transition functions are translations. They show that a result similar to Hurwitz’s one holds, with an explicit bound being 4(g 1); they call Hurwitz translation surfaces the structures which achieve this bound, and characterise them as normal origamis, i.e. square-tiled surfaces which arise as
