论文摘要
在本文中，我们考虑了带有四个奇异性的球体上三角形半滴结构的对称性。我们表明，所有这些表面都可以通过四面体结构产生。使用此构造，我们在$ \ operatotorname {psl}（2，\ mathbb {r}）$中计算每个这样的表面对称组。
In this paper we consider the symmetries of triangulable half-dilation structures on the sphere with four singularities. We show that all such surfaces can be produced by a tetrahedral construction. Using this construction, we calculate each such surface's symmetry group in $\operatorname{PSL}(2, \mathbb{R})$ called the Veech group.
