  • Andrew was embarking on one of the most complex calculations in history.
  • 安德鲁要进行的是史上最为复杂的计算之一。
  • For the first two years, he did nothing but immerse himself in the problem, trying to find a strategy which might work.
  • 在头两年,他其它的事什么都没做,只是埋首于难题当中,试图找到有用的策略。
  • So it was now known that Taniyama-Shimura implied Fermat's last theorem.
  • 现在已经知道谷山-志村猜想暗示了费马最后定理。
  • What does Taniyama-Shimura say?
  • 谷山-志村猜想是怎么说的?
  • It says that all elliptic curves should be modular.
  • 它说所有的椭圆曲线都应为模形式
  • Well this was an old problem, been around for 20 years and lots of people would try to solve it.
  • 这是个老难题了,已有20年左右,许多人尝试解决它。
  • Now one way of looking at it is that you have all elliptic curves and then you have the modular elliptic curves
  • 而如今看待它的一种方式就是,你有了所有的椭圆曲线,接着你又有了模形式椭圆曲线,
  • and you want to prove that there are the same number of each.
  • 你所要证明的就是这两者有同样的数量。
  • Now of course you're talking about infinite sets, so you can't just can't count them per say,
  • 当然了,所谈及的是无限集合,因此当然不能仅靠计数,
  • but you can divide them into packets and you could try to count each packet and see how things gone
  • 但你可将它们分成一族族的,这样就可尽量来数每个族,看看会如何,
  • and this proves to be a very attractive idea for about 30 seconds
  • 头30秒这是个相当吸引人的想法
  • but you can't really get much further than that,
  • 但其实你也只能到那一地步了
  • and the big question on the subject was how you could possibly count, and in fact, Wiles introduced the correct technique.
  • 而关于这个的关键问题在于你如何来计数,实际上,怀尔斯引入了正确的方法。
  • Andrew's trick was to transform the elliptic curves into something called Galois representations which would make counting easier.
  • 安德鲁的方法是将椭圆曲线转化为称为伽罗华表示的形式,这能使计数容易些。
  • Now it was a question of comparing modular forms with Galois representations, not elliptic curves.
  • 现在是将模形式和伽罗华表示、而不是和椭圆曲线进行比较的问题了。
