Groupoid C*-algebras with Hausdorff Spectrum
... Suppose that the maps of H/Hx onto H · x are homeomorphisms for each x ∈ X . The spectrum C ∗ (H n X )∧ is Hausdorff if and only if the map x 7→ Hx is continuous with respect to the Fell topology and X /H is Hausdorff. Note: We can use [Orloff Clark; 07] and [Ramsay; 90] to show that if either X /H ...
