Abstract

fetched live from OpenAlex

Abstract Travelling wave solutions to the vortex filament flow generated by elastica produce surfaces in ℝ 3 that carry mutually orthogonal foliations by geodesics and by helices. These surfaces are classified in the special cases where the helices are all congruent or are all generated by a single screw motion. The first case yields a new characterization for the Bäcklund transformation for constant torsion curves in R 3 , previously derived fromthe well-known transformation for pseudospherical surfaces. A similar investigation for surfaces in H 3 or S 3 leads to a new transformation for constant torsion curves in those spaces that is also derived from pseudospherical surfaces.

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.
