三角化曲面上的几何角结构
Geometric angle structures on triangulated surfaces
摘要:
在本文中,我们描述了一个功能定义在一个三角化的表面,使有一个球面角结构的功能作为边不变量(或Delaunay不变量)的边缘上。我们还刻画了一个函数,使得有一个双曲角结构的功能作为边缘不变。
英文摘要:
In this paper we characterize a function defined on the set of edges of a triangulated surface such that there is a spherical angle structure having the function as the edge invariant (or Delaunay invariant). We also characterize a function such that there is a hyperbolic angle structure having the function as the edge invariant.
