GPT-5.6 Pro helps find a CP^5 counterexample to a long-standing bundle conjecture

- A new result shows that the conjecture “every complex topological vector bundle on projective space is algebraic” is false.
- The counterexample lives on \(CP^5\) and is not only non-algebraizable, but also has no motivic lift.
- The finding also disproves a more recent conjecture by Asok–Fasel–Hopkin, with projective space serving as a stringent test case.
