Abstract

fetched live from OpenAlex

Abstract Using known operator-valued Fourier multiplier results on vector-valued Hölder continuous function spaces C α (ℝ; X ), we completely characterize the C α -well-posedness of the first order degenerate differential equations with finite delay ( Mu )′( t ) = Au ( t ) + Fu t + f(t) for t ∊ ℝ by the boundedness of the ( M, F )-resolvent of A under suitable assumption on the delay operator F , where A, M are closed linear operators on a Banach space X satisfying D(A) İ D(M) ≠ = ﹛0﹜, the delay operator F is a bounded linear operator from C ([ −r , 0]; X ) to X , and r > 0 is fixed.

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.
