In 2000, the Clay Mathematics Institute offered a prize of $1,000,000 for each of seven unsolved problems in math. Among these are the P vs. NP problem, the Poincare Conjecture, Yang-Mills Theory, and the Riemann Hypothesis.
Now, in a strange twist (pointed out to me by J.M. Tyree), a reputable mathematician named Louis de Branges, who has previously proved the Bieberbach conjecture, claims to have proved the Riemann Hypothesis, and has posted his proof on the web. But no mathematician will look at the proof to check if it is correct because, de Branges claims, they don’t like him. Here’s the odd story from the London Review of Books.
