近日，尼日利亚教授奥派耶米•伊诺克(Opeyemi Enoch)成功解决已存在156年的数学难题----黎曼猜想，获得100万美元(约合人民币630万元)的奖金。

黎曼猜想由德国数学家黎曼(Bernard)于1859年提出，其中涉及了素数的分布，被认为是世界上最困难的数学题之一。2000年，美国克莱数学研究所(Clay MathematicsInstitute)将黎曼猜想列为七大千年数学难题之一。
自从费马大定理于20世纪90年代得以解决后，黎曼问题便成为数学界最著名、最受争议的问题。该问题中最简单的部分在于其中所有质数的分布并不遵循规律。
伊诺克博士在尼日利亚某大学任教。他表示，自己在2010年取得关键性突破，这为后来能够解决这一千年难题奠定了基础。他说，自己之所以决定解决这一著名的数学难题不是为了奖金，而是因为自己的学生。正是因为学生们相信自己，他才开始尝试解决这一数学难题。
然而，克莱数学研究所既不证实也不否认伊诺克博士正式解决了这一问题，只是简单表示对这些千年数学难题的解决办法不予评论。
Riemann Hypothesis: Nigerian professor says ''I have solved it''
Nigerian professor Opeyemi Enoch Wednesday insisted he has found a solution to the complex Riemann Hypothesis.
Following several media reports casting doubt on his claim, Enoch said: "I have a proof and the mathematics community is behind me."
The senior lecturer in mathematics at the Federal University in Oye Ekiti, Nigeria, said the project behind solving the 156-year-old math puzzle had taken "seven good years" and that comments from detractors had not dampened his sense of achievement.
"People have the privilege and the right to say whatever they want to say," he said, adding "I have not really been giving attention to some of the comments."
Enoch said he first delivered his findings on November 11 at the International Conference on Mathematics and Computer Science held in Vienna, in an oral presentation called "A Matrix That Generates the Point Spectral of the Riemann Zeta Function."
Nina Ringo, a member of the conference committee, said in an email statement: "I consider his results to be very important and confirm his discovery."
Solving the complex Riemann Hypothesis, which involves the distribution of prime numbers, comes with a $1million prize awarded by the Clay Mathematics Institute (CMI).
Enoch''s says his findings are due for publication by a journal attached to the Vienna conference on December 1. He said he would pass on his paper to the CMI then.
However , it could be years before the CMI accept his solution and award him the prize.
Naomi Kraker, from the CMI told CNN: "To our mind, [the Riemann''s Hypothesis] remains unsolved."
The Massachusetts-based Institute say there are a number of prerequisites before Enoch -- or anyone -- can claim the prize.
Any solution would need to be published in a journal "of worldwide repute" and accepted for two years within the mathematics community before it would be considered, Kraker said.
Enoch says he has received cold calls following reports he has landed the $1million prize, and is concerned about the threat of kidnapping.
"Reports saying I have won $1million have not been helpful for my security or that of my people," he said. "I''ve warned my parents and loved ones to stay away from me."
The Riemann Hypothesis is one of the CMI''s seven Millennium Problems, all of which come with a $1 million prize.
Announced in 2000, as of yet only one has been officially solved, the Poincare Conjecture by Grigoriy Perelman, to whom the prize was offered in 2010. However Perelman refused to accept the award -- as he had the Fields Prize in 2006.
