论文摘要
本文继续研究典型类固醇对应关系的生物学图中的图。我们证明,如果该图在局部紧凑且适当的情况下,则任何此类图都具有群体素模型,并且类固醇模型是局部紧凑的floge thotale groupoid。一个关键的工具是在当地紧凑的Hausdorff空间上空间的相对石材紧凑。
This article continues the study of diagrams in the bicategory of étale groupoid correspondences. We prove that any such diagram has a groupoid model and that the groupoid model is a locally compact étale groupoid if the diagram is locally compact and proper. A key tool for this is the relative Stone-Čech compactification for spaces over a locally compact Hausdorff space.
