ChatGPT Sol 5.6 and Astra 6 help complete proof of Trefethen conjecture

A new paper by John Urschel claims the growth factor for Gaussian elimination with partial pivoting is about √n, and the author says AI interaction turned a hand sketch covering o(n) entries into a full proof.

🔥数学完蛋了!ChatGPT Sol 5.6 + Astra 6 破解 Trefethen 猜想! John Urschel 证明: n\times n 高斯矩阵做部分选主元高斯消元,增长因子以高概率约 \sqrt{n} ,解决数值线性代数里挂了很久的平均情形猜想。 论文自己写的分工:
🔹猜想 1.1:作者先给右下角 o(n) 条目的纯人手草图,AI 交互后补成全证明 🔹其余结果:人手想法 + AI 改进;有的章节作者认为不太需要人手
🔹全文作者本人写;该问题此前在 OpenProblemsInNLA 上仍标 open 论文:https://arxiv.org/abs/2610.06785 同一晚发生的其他AI破解数学难题:
