Riemann hypothesis |
 | | In June 2004, Louis De Branges de Bourcia claimed to have proved the Riemann hypothesis but this has not yet been confirmed (see below). |
 | | In June 2004, Louis De Branges de Bourcia of Purdue University, the same mathematician who solved the Bieberbach conjecture, claimed to have proved the Riemann hypothesis in an "Apology for the proof of the Riemann Hypothesis"[http://www.math.purdue.edu/ftp_pub/branges/apology.pdf](pdf). |
 | | De Branges de Bourcia has announced a proof a number of times, but all of his previous attempts at this proof have failed. |
