  • Riemann surfaces and restrictively-marked hypermaps
    D'Azevedo, Antonio Breda
    If ▫$\mathcal{S}$▫ is a compact Riemann surface of genus ▫$g > 1$▫, then ▫$\mathcal{S}$▫ has at most ▫$84(g - 1)$▫ (orientation preserving) automorphisms (Hurwitz). On the other hand, if ▫$G$▫ is a ... group of automorphisms of ▫$\mathcal{S}$▫ and ▫$\vert G \vert > 24(g - 1)$▫ then ▫$G$▫ is the automorphism group of a regular oriented map (of genus ▫$g$▫) and if ▫$\vert G \vert > 12(g - 1)$▫ then ▫$G$▫ is the automorphism group of a regular oriented hypermap of genus ▫$g$▫ (Singerman). We generalise these results and prove that if ▫$\vert G \vert > g - 1$▫ then ▫$G$▫ is the automorphism group of a regular restrictedly-marked hypermap of genus ▫$g$▫. As a special case we also show that a marked finite transitive permutation group (Singerman) is a restrictedly-marked hypermap with the same genus.
