OpenAI withdraws three math papers after a sign error in one of them
OpenAI's math repository history, dated Oct. 7, lists three withdrawn manuscripts, including one on the rational Hodge conjecture for products of K3 surfaces. The stated reason is that a sign error invalidates a stabilization-trace cancellation argument and the construction two dependent papers use. The withdrawn papers carry notices linking archived copies.
