作为终结余栈的基本广群
The fundamental groupoid as a terminal costack
摘要:
设$X$是一个拓扑空间。我们用$π_0(X)$表示$X$的连通分支集,用$Π_1(U)$表示基本广群。本文证明了对于好拓扑空间,赋值$U\mapstoπ_0(U)$和$U\mapstoΠ_1(U)$分别是终端余层和余栈.
英文摘要:
Let $X$ be a topological space. We denote by $π_0(X)$ the set of connected components of $X$ and by $Π_1(U)$ the fundamental groupoid. In this paper we prove that for good topological spaces the assignments $U\mapstoπ_0(U)$ and $U\mapstoΠ_1(U)$ are the terminal cosheaf and costack respectively.
