Clay Institute Millennium Prize Problems
Regular Plus contributor Lewis Dartnell reports on the scramble for milliondollar prizes that made mathematical headlines at the BA Festival of Science in September 2004.

Can Dan Goldston and Cem Yalcin Yildrim repair the hole in their proof to make the biggest breakthrough in prime number theory for 80 years?

The mathematics of Grigori Perelman may earn him a million dollars, if no holes are found in his proof of the PoincarĂ© Conjecture.

One million dollars is waiting to be won by anyone who can solve one of the grand mathematical challenges of the 21st century. In the second of two articles, Chris Budd looks at the wellposedness of the NavierStokes equations.

One million dollars is waiting to be won by anyone who can solve one of the grand mathematical challenges of the 21st century. But be warned...these problems are hard. In the first of two articles, Chris Budd explains how to hit the bigtime.
