  1. def OAI.HyperbolicObstruction.ConeSkeleton.indexingTarget line 19

    Source documentation

    Zero coefficients specify the base indexing target only: the cover has arbitrary independent weights for each lifted step.

  3. theorem OAI.HyperbolicObstruction.ConeSkeleton.uniform_lifted_picture_chain_zero line 30

    Source documentation

    Normal-form vanishing holds in every regular voltage cover, with each signed lifted cell retained separately. This is stronger than vanishing of the projected base-cell chain.
