Abstract

fetched live from OpenAlex

Given an n n -tuple of positive real numbers ( α 1 , … , α n ) (\alpha _1,\ldots ,\alpha _n) , Konno (2000) defines the hyperpolygon space X ( α ) X(\alpha ) , a hyperkähler analogue of the Kähler variety M ( α ) M(\alpha ) parametrizing polygons in R 3 \mathbb {R}^3 with edge lengths ( α 1 , … , α n ) (\alpha _1,\ldots ,\alpha _n) . The polygon space M ( α ) M(\alpha ) can be interpreted as the moduli space of stable representations of a certain quiver with fixed dimension vector; from this point of view, X ( α ) X(\alpha ) is the hyperkähler quiver variety defined by Nakajima. A quiver variety admits a natural C ∗ \mathbb {C}^* -action, and the union of the precompact orbits is called the core . We study the components of the core of X ( α ) X(\alpha )

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.
