The Jacobian conjecture was (very) recently disproved by a counterexample found by Anthropic's Fable 5. This blog post demonstrates that counterexample using some of the built-in Wolfram Language (WL) functions and entries in Wolfram Function Repository (WFR). We show how to use WL's FindInstance to find three different points which the counterexample polynomial 3-dimensional (3D) transformation…
