Abstract

fetched live from OpenAlex

Let H o m 0 ( Γ<!-- Γ --> , G ) \mathsf {Hom}^{0}(\Gamma ,G) be the connected component of the identity of the variety of representations of a finitely generated nilpotent group Γ<!-- Γ --> \Gamma into a connected compact Lie group G G , and let X 0 ( Γ<!-- Γ --> , G ) \mathsf {X}^0(\Gamma ,G) be the corresponding moduli space. We show that there exists a natural O u t ( Γ<!-- Γ --> ) \mathsf {Out}(\Gamma ) -invariant measure on X 0 ( Γ<!-- Γ --> , G ) \mathsf {X}^0(\Gamma ,G) and that whenever O u t ( Γ<!-- Γ --> ) \mathsf {Out}(\Gamma ) has at least one hyperbolic element, the action of O u t ( Γ<!-- Γ --> ) \mathsf {Out}(\Gamma ) on X 0 ( Γ<!-- Γ --> , G ) \mathsf {X}^0(\Gamma , G) is mixing with respect to this measure.

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.
