| Bio | Ludwig Kraus was a Czech mathematician. In 1884, he published a paper giving a partial proof of the result now known as the two-variable case of the Jacobian conjecture more than half a century before Ott-Heinrich Keller proposed the conjecture in its general form in 1939. Kraus's priority went unrecognized until 2026.2 |
