> A team led by Xu Disheng worked with Shanghai AI Lab’s Intern-S2 model to produce a rigorous proof of the 3D Ghys conjecture. A Peking University team independently verified the core theorems and the proof’s logical completeness using formal machine verification. The paper is on an international preprint platform, and the verification code is open-source.
