How to Read an AI “Counterexample” to the Jacobian Conjecture
Tao’s 2026 digestion of an AI-assisted claim about the Jacobian Conjecture highlights a crucial skill: separate local conditions (Jacobian determinant) from global ones (injectivity). This post explains what the Jacobian Conjecture really asserts and how to verify an alleged counterexample by checking the determinant and explicit collisions.
