Hurwitz group
WebA Riemann surface of genus g is called a Hurwitz surface if it has an automorphism group with the maximal order among all Riemann surfaces of a genus g.The corresponding … WebHere then was Hurwitz's strength -- in developing Klein's ideas [1]:- Klein's new view on modular functions, uniting geometrical aspects such as the fundamental domain with group theory tools such as the congruence subgroups and with topological notions such as the genus of the Riemann surface, was fully exploited by Hurwitz.

We then follow Kulkarni and use the Riemann-Hurwitz Relation to construct a congruence relating the genus g of a surface to the cyclic deficiencies of the symmetry groups that can act on it.
