Abstract

fetched live from OpenAlex

A system of polynomial identities is called finitely based if it is equivalent to some finite system of polynomial identities. Every system of polynomial identities in associative algebras over a field of characteristic 0 is finitely based: this is a celebrated result of Kemer. The first non-finitely based systems of polynomial identities in associative algebras over a field of a prime characteristic have been constructed recently by Belov, Grishin and Shchigolev. These systems of identities are relatively complicated. In the present paper we construct a simpler example of such a system and give a simple self-contained proof of the fact that the system is non-finitely based.

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.
