Samsar creatorAn Announced Counterexample to the Jacobian ConjectureThis scientific explainer examines Levent Alpöge’s announced July 19–20, 2026 counterexample in dimension three. It presents the explicit polynomial map F, verifies its constant Jacobian determinant det J_F = −2, and shows three distinct inputs mapping to the same output, proving noninjectivity and the absence of a polynomial inverse. The construction extends to every n ≥ 3, while the n = 2 case remains open. The result is directly algebraically checkable but not yet conventionally peer-reviewed.View details →The GallerySearch videosLike0Comments0ShareShare
