Dehn fillings of knot manifolds containing essential once-punctured tori
Bibliographic record
Abstract
In this paper we study exceptional Dehn fillings on hyperbolic knot manifolds which contain an essential once-punctured torus. Let M M be such a knot manifold and let β \beta be the boundary slope of such an essential once-punctured torus. We prove that if Dehn filling M M with slope α \alpha produces a Seifert fibred manifold, then Δ ( α , β ) ≤ 5 \Delta (\alpha ,\beta )\leq 5 . Furthermore we classify the triples ( M ; α , β ) (M; \alpha ,\beta ) when Δ ( α , β ) ≥ 4 \Delta (\alpha ,\beta )\geq 4 . More precisely, when Δ ( α , β ) = 5 \Delta (\alpha ,\beta )=5 , then M M is the (unique) manifold W h ( − 3 / 2 ) Wh(-3/2) obtained by Dehn filling one boundary component of the Whitehead link exterior with slope − 3 /

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
