The Mazur-Tate pairing and explicit homomorphisms between Mordell-Weil groups of elliptic curves and ideal class groups
Bibliographic record
Abstract
In [Buell(1977)] and [Soleng(1994)], Buell and Soleng found explicit homomorphismsbetween the Mordell-Weil group of elliptic curves and the ideals class group of quadraticelds, which turn out to be essentially equivalent. After recalling the basic conceptsin the theories of quadratic forms, quadratic elds and elliptic curves, we prove thatSoleng's homomorphism can be obtained via a height pairing introduced by Mazur andTate [Mazur and Tate(1983)], under certain conditions. Then the technique developed inthe proof of this result is used to nd new homomorphisms. Examples of explicit computationsof the Mazur-Tate pairing are also given.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
