Abstract

fetched live from OpenAlex

We introduce families of four-regular graphs consisting of chains of hourglasses which are attached to a finite kernel. We prove a formula for the c 2 invariant of these hourglass chains which only depends on the kernel. For different kernels these hourglass chains typically give rise to different c 2 invariants. An exhaustive search for the c 2 invariants of hourglass chains with kernels that have a maximum of ten vertices provides Calabi-Yau manifolds with point-counts which match the Fourier coefficients of modular forms whose weights and levels are Assuming the completion conjecture, we show that no modular form of weight 2 and level 1000 corresponds to the c 2 of such hourglass chains. This provides further evidence in favour of the conjecture that curves are absent in c 2 invariants of 4 quantum field theory.

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.
