OAI.HyperbolicObstruction.ConeSkeleton.uniform_normal_picture_emptyline 20Source 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) … - theorem
OAI.HyperbolicObstruction.ConeSkeleton.uniform_closed_picture_chain_zeroline 55Source 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) …
