Abstract

fetched live from OpenAlex

Abstract Let A θ be the universal C * -algebra generated by two unitaries U, V satisfying VU = e 2πiθ UV and let Φ be the antiautomorphism of A θ interchanging U and V . The K -theory of R θ = { a ∈ A θ : Φ( a ) = a * } is computed. When θ is irrational, an inductive limit of algebras of the form is constructed which has complexification A θ and the same K -theory as R θ .

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.
