The compactification conjecture for constructible sheaf data on Alexandrov spaces
The compactification conjecture for constructible sheaf data on Alexandrov spaces
Fix a finite field and let consist of pairs , where is an Alexandrov space of Hausdorff dimension at most , diameter at most , curvature at least , and is a constructible object of . The sheaf-moduli topology conjecture. There should exist a Hausdorff topology on this set satisfying the stated sequential compatibility with Gromov–Hausdorff convergence and stabilization of pushforward objects, continuity of the map to constructible-function data and to Alexandrov spaces, closedness under enlargement of , compactness of the closure of smooth manifolds with rank-one constant sheaf, and finiteness of the fibers of the map from that closure to the Alexandrov-space moduli. The source gives no proof of these properties; they are proposed as a framework for compactifying sheaf-theoretic data.
