A world-famous mathematician responsible for solving one of the subject's most challenging problems has published his latest work as a University of Leicester research report.
Mathematically, is it possible to continuously deform a rough sphere into a perfect sphere? Under what situations can we solve the differential equations?
(AP) -- He said nyet to $1 million. Grigory Perelman, a reclusive Russian mathematics genius who made headlines earlier this year for not immediately embracing a lucrative math prize, has decided to decline the cash.
(AP) -- Who doesn't want to be a millionaire? Maybe a 43-year-old unemployed bachelor who lives with his elderly mother in Russia - and who won $1 million for solving a problem that has stumped mathematicians for a century.
