In early April, the mathematics circles had an important matter. 四月初,数学界发生了一件大事。 The publication in the latest issue «Math Yearly journal» on paper, announced the solution of Collatz conjecture. 刊登在最新一期《数学年刊》上的论文,宣布了角谷猜想的解决。 So-called Collatz conjecture, then writes natural number n willfully, if an odd number, then next step turns into 3 n + 1. If an even number, then next step turns into n / 2. After having the circulation of time limit, eventually will fall into inevitably 【4, 2 and 1】 Valley. 所谓角谷猜想,便是任意写出一个自然数n,如果是个奇数,则下一步变成3n+1。如果是个偶数,则下一步变成n/2。经过有限次的循环,最终都会不可避免地跌入【四、二、一】的谷底。 This numbers game, was once fashionable for a time in North America in the 80's. 这个数字游戏,在八十年代的时候曾在北美风靡一时。 Before then, some people have checked up with the aid of Super Computer to below 1.1 trillion natural numbers, and determined, regardless during , the digit inflates to what degree, finally is unable to get rid of „421” curse. 在此之前,已经有人借助超算对11000亿以下的自然数进行过检验,并且确定无论期间数字膨胀到何种程度,最终都无法摆脱“421”的诅咒。 Because this mysterious characteristics, this suspicion was also called „hail suspicion”, because depreciation of digit is swift and violent and irresistible like the hail. 因为这种神奇的特性,这个猜想也被称之为“冰雹猜想”,因为数字的跌落就像冰雹一样迅猛而不可阻挡。 But now, Vera and the others paper, gave this proposition definite proof with the language of math- 而现在,薇拉等人的论文,用数学的语言给了这个命题一个确定的证明- Namely, Collatz conjecture establishes. 即,角谷猜想是成立的。 This paper once were published, then received the extensive attention. 这篇论文一经发表,便受到了广泛的关注。 Let in abundance the surprise, not only proof of Collatz conjecture, is this paper mainly completes the person is the Lu Zhou student. 让外界纷纷诧异的不只是角谷猜想的证明,更是这篇论文的主要完成人是陆舟的学生。 According to the convention, the proof of this significant conjecture, often is not a paper can handle. Besides the approval of authority Journal, the voucher also needs to obtain the approval of entire mathematics circles to be good. 按照惯例,这种重大的数学猜想的证明,往往不是一篇论文就能搞定的。除了权威期刊的认可之外,证明者还需要得到整个数学界的认可才行。 Under normal conditions should be Princeton arranges a public lecture for Vera and the others, reports related research results, and answered the same domain scholar's question. 通常情况下应该是普林斯顿为薇拉等人安排一场报告会,来汇报相关的研究成果,并且回答同领域学者的提问。 However happen to catches up in August is once every four years International Mathematics Congress, this public lecture then did for somebody by more authoritative International Mathematical Union . 不过正好赶上八月份是四年一度的国际数学家大会,这场报告会便由更权威的国际数学家联盟来代劳了。 In discussing the second week after Wendeng publication, the Princeton tenured professors and «Math Yearly journal» editor-in-chief Professor Peter Sagnak, found Lu Zhou, and brought an invitation from International Mathematical Union . 就在论文登刊之后的第二个星期,普林斯顿终身教授、《数学年刊》总编彼得・萨纳克教授,找到了陆舟,并且带来了一封来自国际数学家联盟的邀请函。 Few people at the same International Mathematics Congress, receive two invitations simultaneously. 很少有人在同一届国际数学家大会上,同时收到两张邀请函。 At least in Sagnak's mind does not have. 至少在萨纳克的印象中是没有的。 „...... Imu congress organizing committee chairman Professor Viane sent in a mail to me, hopes that I transmit this written communication to you. The certificate of Collatz conjecture this significant conjecture should be known by more people. The opportunity is happen to rare, immediately is the International Mathematics Congress, they arranged 45 minutes of public lectures for you specially, looked that you have the time?” “……imu大会组织委员会主席维亚纳教授向我发来了一封邮件,希望我将这封书面信件转交给你。角谷猜想这种重大数学猜想的证明应该被更多人知道。正好机会难得,马上就是国际数学家大会,他们特别为你安排了一场四十五分钟的报告会,看你这边有没有时间？” Looks at Professor Sagnak, Lu Zhou shakes the head saying: „I have one hour of public lecture, moreover I was very recently busy, perhaps does not have the time to prepare the second public lecture.” 看着萨纳克教授,陆舟摇了摇头说道:“我已经有一场一小时报告会了,而且我最近很忙,恐怕没有时间准备第二场报告会。” Sagnak eyebrow selected selecting: „About the ns equation?” 萨纳克眉毛挑了挑:“关于ns方程？” „Ns” topic-based group applied to open the topic in the higher research institute officially, regarding Lu Zhou and cooperation between Professor Fefferman, in Princeton was not secret. “ns”课题组在高等研究院是正式申请了开题的,对于陆舟和费弗曼教授之间的合作,在普林斯顿并不是什么秘密。 What surprised Sagnak was, this topic opened the topic at the end of the year before last year, by present even also less than one year. 只不过令萨纳克意外的是,这个课题在前年年末才开题,到现在甚至还不到一年的时间。 Clearly, he does not think that Lu Zhou and Fefferman can in such a short time complete the proof of that millennium difficult problem. 很明显,他不认为陆舟和费弗曼能在这么短的时间里完成那个千禧难题的证明。 However the reply of Lu Zhou, actually came as a surprise to his. 然而陆舟的回答,却是出乎了他的意料。 Lu Zhou nods: „Yes.” 陆舟点头:“是的。” Heard this unexpected answer, Professor Sagnak on the face showed the surprised expression: „You had confidence that can the solution before August come out? Can the time be too short.” 听到了这个意料之外的答案,萨纳克教授脸上露出了惊讶的表情:“你这么有把握能在八月份之前解出来吗？时间会不会太短了点。” Lu Zhou smiles, continued to answer this issue relaxed. 陆舟笑了笑,语气轻松地继续回答了这个问题。 „When a tool was completed, fulfills its mission is only the time issue. I have this premonition, you should be clear about this feeling.” “当一件工具被完成,履行它的使命只是时间问题。我有这种预感,你应该清楚这种感觉吧。” Professor knits the brows slightly, later immediately then responds. 萨奈克教授微微皱眉,随后立刻便反应了过来。 „Tool that you said that is you submitted a piece of writing recently in «Math Yearly journal» on that about ‚the l manifold’ the paper?” “你所说的工具,难道是你最近投稿在《数学年刊》上的那篇关于‘l流形’的论文？” Lu Zhou nods with a smile: „, In my opinion, it is solves the ns equation the key.” 陆舟笑着点了点头:“正是,在我看来,它是解决ns方程的关键。” Hears this affirmative reply, Professor in the heart is filled with emotion. 听到这肯定的回答,萨奈克教授心中感慨万千。 Before that paper him, is to hear, because it stirred a big controversy in " Math Yearly journal » editorial department. 那篇论文他之前是听说过的,因为它在《数学年刊》编辑部引起了不小的争议。 Although the originality of this special differential manifold is without a doubt, but many academic editors cannot look, this thing has what significance, or is useful. 虽然这个特殊的微分流形的新颖性是毋庸置疑,但不少学术编辑都看不出来,这东西到底有什么意义,或者说有什么用处。 Sagnak also cannot look, even if he does not know nothing about the parital differential domain. 萨纳克同样看不出来,即便他对偏微分领域并非一无所知。 However finally, his decision received the Lu Zhou manuscript, arranging it to enter the link of peer review. 不过最终,他还是拍板接收了陆舟的稿件,安排它进入了同行评审的环节。 Now looks like, he decided initially also is really a visionary matter...... 现在看来,他当初的决定还真是一件富有远见的事情…… ...... …… After Professor said goodbye, Lu Zhou takes the invitation of imu congress, went to the office of higher research institute, called his three postgraduate candidates in the same place held the internal conference. 与萨奈克教授告别之后,陆舟拿着imu大会的邀请函,前往了高等研究院的办公室,将他的三名博士生召集在一起开了个内部会议。 „In my hand is invitation about International Mathematics Congress 45 minutes of report, although the congress organizer invited me to make the related report, but I felt compared with me, you needed this opportunity.” “我手上是一封关于国际数学家大会四十五分钟报告的邀请函,虽然大会主办方邀请我作相关报告,但我觉得比起我,你们更需要这个机会。” Stopped the moment, the line of sight of Lu Zhou stayed a while on the faces of three students respectively, then continued to say. 停顿了片刻,陆舟的视线在三名学生的脸上分别停留了一会儿,然后继续说道。 „According to the convention, the public lecture is reported by main paper completion, I will recommend Vera to International Mathematical Union as the speaker, your opinions?” “按照惯例,报告会由主要论文完成者进行汇报,我会向国际数学家联盟推荐薇拉作为报告人,你们的意见呢？” Qin Yue: „Agreement!” 秦岳:“同意！” Hardy: „Seconds the motion!” 哈迪:“附议！” The voting passes by the overwhelming advantage. 投票以压倒性的优势通过。 Looks two students who raise hand, Lu Zhou nods, said joyfully: „It seems like we reached the agreement.” 看着举手的两位学生,陆舟点了点头,欣然道:“看来我们达成了共识。” Saw itself in a flash selling by two teammates, Vera somewhat worried immediately: „Waits for, I......” 见自己一瞬间被两名队友给卖了,薇拉顿时有些着急:“等一下,我……” Hardy grins said with a smile: „You did not need to modestly decline, the main part of paper was you completes, this report naturally should go by you.” 哈迪咧嘴笑着说道:“你就不用谦让了,论文的主要部分是你完成的,这个报告自然应该由你去。” Somewhat looked at Lu Zhou one embarrassed, because Vera's voice becomes some stutter intense: „But I have not made the report...... I even simply not to participate at the imu congress.” 有些窘迫地看了陆舟一眼,薇拉的声音因为紧张变得有些结结巴巴:“可是我从来没在imu大会上做过报告……我甚至根本没参加过。” „There is nothing, I am also first participation, even the first time is went to Brazil, when the time comes perhaps must trouble Hardy to work as the guide,” Lu Zhou smiles, with encouraging the tone said that „you do at the public lecture of Berkeley Branch school is not good? I remember that you also received the certificate of best youth speaker. So long as you remember, the normal display on the stage was OK.” “这没什么,我也是第一次参加,甚至是第一次去巴西,到时候恐怕还得麻烦哈迪当向导,”陆舟笑了笑,用鼓励的口吻说道,“你在伯克利分校的报告会做的不是挺好的吗？我记得你还拿到了最佳青年报告人的证书。你只要记住,在台上正常发挥就可以了。” Hears encouragement of Lu Zhou, Vera became slightly calm, but on face tense expression, still has not relaxed thoroughly. 听到陆舟的鼓励,薇拉变得稍微冷静了一些,不过脸上紧张的表情,依然没有彻底缓和下来。 Looks at Vera that disturbed appearance, sometimes Lu Zhou really cannot bear the suspicion, is she really a Slav? 看着薇拉那副忐忑的样子,有时候陆舟真的忍不住怀疑,她真的是斯拉夫人吗？ Although he had not deeply understood other Slav are what appearances, the impression of but according to him in various movies obtaining, he is unable the timid and shy these two word and in bandit word match. 虽然他没深入了解过其它斯拉夫人是什么样子,但根据他在各种电影中得到的印象,他怎么也无法将胆小、怕生这两个单词和毛子这个单词匹配上。 , Lu Zhou continued: „In brief, too should not be serious it, regards is the ordinary public lecture prepares well. Let alone your also four months can prepare slowly.” 顿了顿,陆舟继续说:“总之,别太将它当一回事,就当成是普通的报告会去准备就好。更何况你还有四个月的时间可以慢慢准备。” The finger pinches the lower hem corner, Vera is asking low voice: „Can you help me?” 手指捏着衣角,薇拉小声问道:“你可以帮我吗？” Lu Zhou shakes the head: „This time is not perhaps good.” 陆舟摇了摇头:“这次恐怕不行。” Looks that Wei had a long face the expression that lost slightly, Lu Zhou stopped the moment, continued to say. 看着薇拉脸上略微失落的表情,陆舟停顿了片刻,继续说道。 „Has waited for today, I will continue to start to close up, this public lecture, you can depend upon, only then you.” “等过了今天,我会继续开始闭关,这次报告会,你能依靠的只有你自己。”
