论文摘要
在本文中，我们研究了带有一组射线的理性多面体风扇的几何形状和组合。 我们考虑的主要问题是当这样的粉丝投影，完整或简单时。为了回答这些问题，我们使用不变理论的技术来表征圆环表示中最大饱和开放式集合的商。
In this paper we study the geometry and combinatorics of the possible rational polyhedral fans with a given set of rays. The main questions we consider are when such fans are projective, complete, or simplicial. To answer these questions we use techniques of invariant theory to characterize the quotients of maximal saturated open sets in torus representations.
