Selecting good sampled sheets for an entire horizontal segment

  1. theorem OAI.PolycyclicRecognition.exists_good_profiles_along_segment line 19

    Source documentation

    A supported weak profile limit gives one slowly improving family of good sheets on a compact neighborhood of the entire actual late segment. The endpoint scheme can be fixed before this selection.
