分层空间上的栈

Stacks on stratified space

Delphine Dupont

摘要:

本文研究了可构造栈的2-范畴SSS_n.可构造栈的概念是由D.特雷曼它是可构造层的自然推广。D. Treumann还介绍了出口路径2范畴,这是一个分层版本的基本2广群,他表明,这两个2范畴是等价的。我们的方法不同。证明了SSS_n与以2-表示的组合数据、2-表示的函子和函子的同构为对象的2-范畴之间的2-等价性。

英文摘要:

In this paper, we go into the study of the 2-category SSS_Σof Σ-constructible stacks. The notions of constructible stack was introduced by D. Treumann. It is a natural generalization of constructible sheaf. D. Treumann has also introduced the exit-path 2-category, which is a stratified version of the fundamental 2-groupoid and he has showed that these two 2-categories are equivalent. Our approach is different. We show the 2-equivalence between SSS_Σand a 2-category whose objects are combinatoric data of 2-representations, functors of 2-representations and isomorphisms of functors.
