我们研究通过在代数环面的子簇的非阿基米德 amoeba 上施加足够精细的多面体结构所定义的这些子簇的紧化。这些紧化具有许多良好的性质,例如任何\(k\)个边界除子在余维数\(k\)处相交。我们考虑一些例子,包括\(M_{0,n}\subset M_{0,n}\)(更一般地,超平面排列补集的对数典范模型)以及格拉斯曼流形被一个极大环面的紧商。
We study compactifications of subvarieties of algebraic tori defined by imposing a sufficiently fine polyhedral structure on their non-archimedean amoebas. These compactifications have many nice properties, for example any k boundary divisors intersect in codimension k. We consider some examples including M0,n ⊂ M0,n (and more generally log canonical models of complements of hyperplane arrangements) and compact quotients of Grassmannians by a maximal torus.
