Abstract

fetched live from OpenAlex

In this paper, we consider N, a simply connected two-step nilpotent Lie group with N , its corresponding (two-step nilpotent) Lie algebra, and we study Newton's method for solving the equation f (x) = 0, where f : N → N is a mapping.Under certain generalized Lipschitz condition, we obtain the convergence radius of Newton's method and the estimation of the uniqueness ball of the zero point of f .Some applications to special cases including Kantorovich's condition and γ-condition are provided.The determination of an approximate zero point of an analytic mapping is also presented.

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.
