Abstract

fetched live from OpenAlex

Given a prime number p , we study topological analogues of Iwasawa invariants associated to \mathbb{Z}_p -covers of the 3 -sphere that are branched along a link. We prove explicit criteria to detect these Iwasawa invariants, and apply them to the study of links consisting of 2 component knots. Fixing the prime p , we prove statistical results for the average behaviour of p -primary Iwasawa invariants for 2 -bridge links that are in Schubert normal form. Our main result, which is entirely unconditional, shows that the density of 2 -bridge links for which the \mu -invariant vanishes, and the \lambda -invariant is equal to 1 , is (1-\frac{1}{p}) . We also conjecture that the density of 2 -bridge links for which the \mu -invariant vanishes is 1 , and this is significantly backed by computational evidence. Our results are proven in a topological setting, yet have arithmetic significance, as we set out new directions in arithmetic statistics and arithmetic topology.

Not 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.
