Abstract

fetched live from OpenAlex

Abstract For p ≥ 1, one can define a generalisation of the unknotting number tu p called the p th untwisting number, which counts the number of null-homologous twists on at most 2 p strands required to convert the knot to the unknot. We show that for any p ≥ 2 the difference between the consecutive untwisting numbers tu p –1 and tu p can be arbitrarily large. We also show that torus knots exhibit arbitrarily large gaps between tu 1 and tu 2 .

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
