  1. theorem OAI.HyperbolicObstruction.ConeSkeleton.uniform_normal_picture_empty line 20

    Source documentation

    Unbounded normal spherical-picture vanishing. The size cutoff is in the rank EVENT, not in the picture: the theorem applies to every finite normal picture for that realization, without any assumed separator interface.

    theorem uniform_normal_picture_empty {α β δ : ℝ}
        (ha : 0 < α) (hb : 7*α < β) (hd : 0 < δ) :
        ∃ K : ℕ, 0 < K ∧ ∀ (n : ℕ)
          (w : TableModel.Entry (A := Alphabet n) rowSupport → Bool)
    …

  2. theorem OAI.HyperbolicObstruction.ConeSkeleton.uniform_closed_picture_chain_zero line 55

    Source documentation

    Every literal genus-zero closed picture carries zero chain, after the proved finite normal-form surgeries. This is not yet the topological theorem that a nonzero Hurewicz cycle admits such a picture.

    theorem uniform_closed_picture_chain_zero {α β δ : ℝ}
        (ha : 0 < α) (hb : 7*α < β) (hd : 0 < δ) :
        ∃ M : ℕ, 0 < M ∧ ∀ (n : ℕ)
          (w : TableModel.Entry (A := Alphabet n) rowSupport → Bool)
