## AI 摘要

Anthropic 的 Claude Fable 5 给出了一个可手工验证的反例，推翻了自 1939 年悬而未决的雅可比猜想。该猜想认为，若多项式映射的雅可比行列式为非零常数，则其必有多项式逆映射。Fable 5 在周日晚间轻松解决了这一 87 年难题。

## 正文

Claude Fable 5 has produced a hand-checkable counterexample to the Jacobian conjecture， an open problem dating to 1939.

The conjecture says that a polynomial map with a constant non-zero Jacobian determinant must have a polynomial inverse.

An 87-year-old problem was casually solved by Fable 5 on a sunday evening. Insane times to live in.
