WebAbstract: We introduce moduli spaces of stable perverse coherent systems on small crepant resolutions of Calabi–Yau 3-folds and consider their Donaldson–Thomas-type counting invariants. The stability depends on the choice of a component ( = a chamber) in the complement of finitely many lines ( = walls) in the plane. We determine all walls and … Web16. máj 2000 · Perverse coherent sheaves (after Deligne) Roman Bezrukavnikov.

WebAs a result the derived category of -modules is realized as a full subcategory of coherent sheaves on this stack, confirming expectations from strong forms of the local Langlands correspondence (including recent conjectures of Hellmann and Zhu). ... in terms of categories of perverse sheaves (as previously observed in local Langlands over ℝ). WebIn the proof we use the theory of perverse coherent sheaves in order to glue local pieces of the rigid dualizing complex into a global complex.
