单词 | Cubic Surface |
释义 | Cubic SurfaceAn Cayley Schoutte (1910) showed that the 27 lines can be put into a One-to-One correspondence with the vertices of a particularPolytope in 6-D space in such a manner that all incidence relations between the lines are mirrored in the connectivityof the Polytope and conversely (Du Val 1931). A similar correspondence can be made between the 28 bitangents of thegeneral plane Quartic Curve and a 7-D Polytope (Coxeter 1928) and between the tritangent planes of the canonicalcurve of genus 4 and an 8-D Polytope (Du Val 1933). A smooth cubic surface contains 45 Tritangents (Hunt). The Hessian of smooth cubic surface containsat least 10 Ordinary Double Points, although the Hessian of the Cayley Cubiccontains 14 (Hunt).
