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.
