On stratifications and poset-stratified spaces
Abstract
A stratified space is a topological space equipped with a stratification, which is a decomposition or partition of the topological space satisfying certain extra conditions.More recently, the notion of posetstratified 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.
