Abstract

fetched live from OpenAlex

We initiate the study of circular-orderability of 3-manifold groups, motivated by the L-space conjecture.We show that a compact, connected, P 2 -irreducible 3-manifold has a circularly orderable fundamental group if and only if there exists a finite cyclic cover with left-orderable fundamental group, which naturally leads to a "circular-orderability version" of the L-space conjecture.We also show that the fundamental groups of almost all graph manifolds are circularly orderable, and contrast the behaviour of circular-orderability and left-orderability with respect to the operations of Dehn surgery and taking cyclic branched covers.03C15, 06F15, 20F60, 57M50, 57M60

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.
