As a … Webexample, when a (locally compact) group G acts on a locally compact Hausdorff space X, the quotient space X/G may not be well behaved, e.g. may not be even a Hausdorff space. The crossed product (C∗−) algebra C0(X) ⋉ G, however, is a good replacement for X/G [3]. In fact, if the action of G is free and proper, then

WebMay 6, 2024 · 1 Answer. Sorted by: 3. First, one can pull back the Čech cocycle to S^1 and work directly with S^1 instead of X. Any two open covers have a common refinement, so it suffices to show that the monodromy map does not change under passing to refinements. As already pointed out in the comments, the open cover must be cyclic: U0 = Un. WebOct 18, 2024 · Cocycle superrigidity for profinite actions of irreducible lattices. Let be an irreducible lattice in a product of two locally compact groups and assume that is densely embedded in a profinite group . We give necessary conditions which imply that the left translation action is "virtually" cocycle superrigid: any cocycle with values in a ... elmo covid shot
