AI helps mathematician crack 80-year-old Jacobian conjecture with verified counterexample

The Jacobian conjecture, which had stumped mathematicians for over 80 years, has been disproved by Levent Alpöge working alongside AI model Claude Sonnet 5. Alpöge published a simple, independently verifiable counterexample, sending shockwaves through the mathematics community. It is one of the first instances of AI playing a decisive role in resolving a major, long-standing mathematical problem.
