摘要翻译:
给定一个(n-1)维环面对一个n维正规仿射簇的有效作用,Mumford构造了一个环面嵌入,而Altmann和Hausen则用曲线上的多面体因子来描述。我们将环面嵌入的扇形与此多面体因子进行了比较。

英文摘要:
Given an effective action of an (n-1)-dimensional torus on an n-dimensional normal affine variety, Mumford constructs a toroidal embedding, while Altmann and Hausen give a description in terms of a polyhedral divisor on a curve. We compare the fan of the toroidal embedding with this polyhedral divisor.
