Pach's Tangency Conjecture: Improved Bounds

partialconfidence 70%

VibeMathed reports this item as partial. VibeMath preserves that report as a source assertion and has not independently authored a plain-language mathematical explanation.

Precise statement

Pach conjectured that $n$ Jordan arcs, pairwise crossing exactly once with no triple points, have $O(n)$ tangent pairs. The best known bound stood at $O(n^{7/4})$; the paper improves it to $O(n^{3/2})$ (and $O(n^{5/3})$ in the at-most-one-crossing relaxation), plus a tight $\Theta(n^{4/3})$ for a grounded x-monotone variant.

The source statement is reproduced for indexing with attribution. Mathematical correctness requires domain-expert or mechanical review. VibeMath has not independently audited statement fidelity, correctness, priority, or novelty.

What AI did

Gemini

"For the proof of Theorem 9 we used some back and forth interaction with Google's Large Language Model Gemini." One theorem of the paper, attributed plainly.
