Abstract

fetched live from OpenAlex

Let G be a group with involution * and σ : G → {±1} a group homomorphism. The map ♯ that sends α = ∑ α g g in a group ring RG to α ♯ = ∑ σ(g)α g g* is an involution of RG called an oriented group involution. An element α ∈ RG is symmetric if α ♯ = α and skew-symmetric if α ♯ = -α. The sets of symmetric and skew-symmetric elements have received a lot of attention in the special cases that * is the inverse map on G or σ is identically 1, while the general case has been almost ignored. In this paper, we determine the conditions under which the set of elements that are skew-symmetric relative to a general oriented involution form a subring of RG. This is the sequel to another paper where the analogous problem for the symmetric elements was studied, with a small oversight that is corrected here.

Full frame distilled prediction

Teacher imitation

Not 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.
