WebSuperfície de Macbeath. Na teoria da superfície de Riemann e na geometria hiperbólica, a superfície de Macbeath, também chamada curva de Macbeath ou curva de Fricke-Macbeath, é a superfície do gênero 7 de Hurwitz. O grupo automorfismo da superfície Macbeath é o grupo simples PSL (2,8), constituído por 504 simetrias. [ 1] WebIn 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 1893). They are also referred to as Hurwitz curves, interpreting …

WebRiemann-Hurwitz Relation, which will in turn allow us to develop Hurwitz’s Inequality, an upper bound on the order of a symmetry group of a given surface. 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. WebThe group for which the maximum is reached is called the Hurwitz group, and the corresponding Riemann surface is called the Hurwitz surface. Since compact Riemann … the stationmaster\u0027s daughter
Riemann, Hurwitz, and Branched Covering Spaces
http://simonrs.com/eulercircle/rtag2024/amulya-klein.pdf Web13 mrt. 2008 · Hurwitz's paper thereby applies to show the connectedness of the moduli space of compact surfaces of genus g. Nowadays Hurwitz spaces refer more generally to moduli spaces of covers with specified Galois covering group and with precise constraints on the ramification. The data for that is a Nielsen class with an equivalence relation. 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 function $${\displaystyle h(g)}$$ mapping the genus to the number of Hurwitz surfaces with that genus is unbounded, even though most of its values … Meer weergeven • Hurwitz quaternion order Meer weergeven myth and reality of king ajisaka in ijjshi
