俄罗斯记者葛森(Gessen)的著作。
西方数学家就像前苏联发射第一艘载人飞船“Sputnik号”一样备受打击。西方的数学界光是理解和验证佩雷尔曼的解法,就花去了3年时间。

Hamilton的Ricci flow idea虽然看上去有点意思,不过多数数学家也不相信Poincare
猜想最终会被这么ugly的方法证明,老丘虽然事后诸葛亮号称自己当时就认为这个方法
有戏,其实还是心里没底,不然他自己肯定就去拼这个问题了。现在谁也不敢说wiles

不知道某些人是不是真是做数论的,如果真是的话,有这番言论就不应该了。公平地说,
自从改革开放以后,国内媒体对陈景润和哥德巴赫猜想的宣传确实是过头的,包括对华
罗庚的宣传也有过头之嫌。但那时是时势所迫,中国百废待兴,需要一些偶像来鼓舞士
气。这个暂且不论。
至于哥德巴赫猜想的地位,这么说吧,它绝对不是数论里面的核心问题,更不是什么皇
冠上的
明珠。但是,由于它已经被提出有两百多年了,难度摆在那里,就像Fermat's Last
Theorem,
象征意义多于它的实际意义。但是倘若有机会攻克这样的问题而不取,那肯定脑子有问
题吧。
你可能说Andrew Wiles 是证明了Taniyama-Shimura, 这个比FLT有意思多了。可是歌德
巴赫,又何尝不是如此呢。想想上世纪60,70年代的时候,... 阅读全帖 |
