Abstract

fetched live from OpenAlex

We build a parallel theory of simple Hurwitz numbers for the reflection groups G(m,1,n) . We study analogs of the cut-and-join operators. An algebraic description as well as a description of Hurwitz numbers in terms of ramified coverings is provided. An explicit formula for them in terms of Schur polynomials is given. In addition, the generating function of G(m,1,n) -Hurwitz numbers is shown to give rise to an m independent-variables \tau -function of the KP hierarchy. Finally, we provide an ELSV-type formula for these new Hurwitz numbers. These results extend the results of Fesler (2023).

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.
