Abstract

fetched live from OpenAlex

The Leray-Hopf solutions to the Navier-Stokes equation are known to be unique on R 2 . We show the uniqueness of the Leray-Hopf solutions breaks down on H 2 (-a 2 ), the two dimensional hyperbolic space with constant sectional curvature -a 2 . We also obtain a corresponding result on a more general negatively curved manifold for a modified geometric version of the Navier-Stokes equation. Finally, as a corollary we also show a lack of the Liouville theorem in the hyperbolic setting both in two and three dimensions. Contents 1. Introduction 43 Acknowledgements 54 2. Preliminaries 54 3.

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.
