中文摘要 AI 辅助
我们为 Pierce-Birkhoff 猜想提供了一个反例:一个连续函数,在划分 $\mathbb{R}^n$ 的有限个半代数集上逐段二次,但无法表示为多项式的有限格组合。该反例是在我们的多智能体、多模型设置(串联 GPT 5.6、GPT 6、Claude Opus 5 和 Claude Fable 5.1)的协助下发现的。
英文摘要
We provide a counterexample to the Pierce-Birkhoff conjecture: a continuous function that is piecewise quadratic on a finite collection of semialgebraic sets that partition $\mathbb{R}^n$ but that cannot be expressed as a finite lattice combination of polynomials. The counterexample was found with the assistance of our multi-agent, multi-model setup that chains together GPT 5.6, GPT 6, Claude Opus 5, and Claude Fable 5.1.
