Supported Cartan sheets agree above an interior generator switch

  1. theorem OAI.PolycyclicRecognition.rescaledMapProfile_suffix_dist_le line 17

    Source documentation

    At a fixed chart point, changing the suffix changes the profile by at most the normalized distance between the two right-positioned sheets.
