摘要
分层空间是一个拓扑空间,它具有一个分层映射,是拓扑空间满足某些额外条件的分解或分割。最近,"poset-stratified space "的概念得到了推广,即拓扑空间被赋予了一个连续的映射到一个具有亚历山德罗夫拓扑的poset。这两个分层空间概念在数学中无处不在,从代数几何中对星状结构的研究到高范畴理论中对同调假说的扩展,不一而足。在本文中,我们将研究这些不同的分层空间方法之间的精确数学关系。
A stratified space is a topological space equipped with a
\emph{stratification}, which is a decomposition or partition of the topological
space satisfying certain extra conditions. More recently, the notion of
poset-stratified space, i.e., topological space endowed with a continuous map
to a poset with its Alexandrov topology, has been popularized. Both notions of
stratified spaces are ubiquitous in mathematics, ranging from investigations of
singular structures in algebraic geometry to extensions of the homotopy
hypothesis in higher category theory. In this article we study the precise
mathematical relation between these different approaches to stratified spaces.
