The pro-homology conjecture for cosheaf homology satellites
The pro-homology conjecture for cosheaf homology satellites
Let be a topological space, let be its standard site, and let be the site of normal open sets. Write for the cosheaf homology and for the left satellites of .
Pro-homology conjecture. On the standard site , if is Hausdorff paracompact, then
H_n\left(X,\operatorname{pro}\relax\protect\ifmmode\expandafter\text@\else\expandafter\text\fi{-}H_0(\bullet,A)\right)=H_n(X,A_{\#}):=L_nH_0(X,A_{\#})\simeq \operatorname{pro}\relax\protect\ifmmode\expandafter\text@\else\expandafter\text\fi{-}H_n(X,A).The same isomorphisms should hold on for all topological spaces. This conjecture identifies the derived cosheaf-theoretic construction with shape pro-homology under the stated hypotheses; the paper notes that general spaces may lack suitable polyhedral expansions, so the unrestricted comparison remains unavailable.
