非阿基米德和热带几何学中的卡塔

Skeleta in non-Archimedean and tropical geometry

Andrew W. Macpherson

摘要:

我描述了代数几何理论的Eketa,它提供了一个统一的设置为研究热带品种,Eketa的非阿基米德解析空间,和仿射流形的奇异性。拓扑半环是具有拓扑半环的结构层的空间,并且局部地以拓扑半环的谱为模型。本文的主要结果是:非阿基米德解析空间的拓扑空间可以局部地从其解析函数的“逐点赋值”层恢复.

英文摘要:

I describe an algebro-geometric theory of skeleta, which provides a unified setting for the study of tropical varieties, skeleta of non-Archimedean analytic spaces, and affine manifolds with singularities. Skeleta are spaces equipped with a structure sheaf of topological semirings, and are locally modelled on the spectra of the same. The primary result of this paper is that the topological space underlying a non-Archimedean analytic space may locally be recovered from the sheaf of `pointwise valuations' of its analytic functions.
