Abstract

fetched live from OpenAlex

We investigate the growth of the periods of periodic solutions of ordinary differential equations which are arbitrarily close to an isolated equilibrium point. More precisely, we estimate the period of periodic orbits near a completely degenerate equilibrium point (the derivative of the vector field at the equilibrium point is identically zero) and show that it tends to infinity as the amplitude of the orbits tends to zero.

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.
