An Anthropic mathematician utilized the Claude Fable 5 AI to find a counterexample to the Jacobian conjecture, a problem that has challenged mathematicians for decades. The discovery demonstrates the conjecture is false in higher dimensions.
A mathematician working at Anthropic says he used the AI model Claude Fable 5 to uncover a remarkably simple counterexample to the Jacobian conjecture, a famous problem that has resisted mathematicians for more than a century. The result shows that the conjecture is false in three dimensions and above, although the original two-dimensional version remains unsolved.
The Jacobian conjecture posits a relationship between the derivatives of polynomial functions and their algebraic properties. It has been a significant open problem in mathematics since it was first proposed in 1939. While mathematicians have verified the conjecture for specific cases, a general proof—or disproof—has remained elusive until now. The use of AI allowed for a novel approach to tackling this complex mathematical challenge.
The discovery doesn't resolve the entire mystery surrounding the Jacobian conjecture; it specifically demonstrates its falsehood in three dimensions and above. The two-dimensional version of the conjecture remains unproven, leaving room for further research and investigation.
We don't rate truth. We strip the spin and show you which perspectives covered the story. You decide.
