Existence of groupoid models for diagrams of groupoid correspondences
Abstract
This article continues the study of diagrams in the bicategory of \'etale groupoid correspondences. We prove that any such diagram has a groupoid model and that the groupoid model is a locally compact \'etale groupoid if the diagram is locally compact and proper. A key tool for this is the relative Stone-Cech compactification for spaces over a locally compact Hausdorff space.
