After Vera’s report ended, it not only caused a warm response at the conference, but also attracted the attention of the media at the International Congress of Mathematicians.

For a long time, the mathematics community has always been considered a male field, and few women can make outstanding achievements in this field. And this means that the impact of any outcome will be magnified.

What's more, as a digital game that has been popular in North America, the difficulty of the proposition of Kakutani is not low.

However, what regrets the media is that the young female mathematician does not seem to like being interviewed, or some fear of being touched by the camera.

Fortunately, although she did not interview Vera herself, her tutor was better able to speak.

The third day after the end of the report, the fourth day of the International Congress of Mathematicians.

The reporters of the bbc science column made an appointment with Lu Zhou for a brief interview in a cafe near the Barra da Tijuca hotel.

Bbc reporter: "...we all know that there are two reports that will be relevant to you. The proof of the Kakuya guess is a report completed by your student, Ms. Vera Puyui. How do you rate your students? ?"

Lu Zhou: "Weila is a very good student, including her two other collaborators, Qin Yue and Hardy. The talent in number theory is also very good. I think that gender is not a problem that needs to be paid attention to. Among the scholars I know, there are also very good women."

Bbc reporter: "I heard that she got your guidance while studying the Gu Gu Guxiang. Many people think that this conjecture is actually solved by you. How do you think about these remarks or rumors?"

Lu Zhou smiled and said: "What I have provided is only the solution to the problem, and the methodological guidance to them, and the whole proof is indeed done by themselves. This is beyond doubt. Moreover, it turns out that the group structure method It is also an excellent number theory method that can be used to solve many problems in additive number theory."

Reporter: "So, with regard to group formation, what is the most optimistic about which problem it is used to solve? Or, which field is the proposition?"

Lu Zhou said with a smile: "Do you really want me to say it? Actually, I think even if I don't say it, my colleagues can probably see it."

The reporter grinned and said: "You still have to talk about it, take care of our laymen."

Lu Zhou thought for a moment and replied briefly: "Hua Lin."

Among many additive number theory issues, the Hualin problem can be said to be one of the classic propositions.

This proposition originated from the "Algebra Meditation" published by Hualin in 1770. In the writing, Edward Hualin himself guessed that for each non-one positive integer k, there is a positive integer g(k), so that each A positive integer can be expressed as the sum of up to g(k) k-th powers.

As a classic problem in additive number theory, there are not many people who are engaged in research on this issue.

The existence of g(k) has been proved by Hilbert in a complicated way, and the case of g(2)=4 is the quadratic sum theorem, which was proved by Lagrange in the eighteenth century.

Among the later researchers, Weiyfreich, Balasubra Manian, and Chen Jingrun proved g(3), g(4), and g(5), respectively.

If you want to ask Lu Zhou what is the most optimistic about which problem to solve, then there is no doubt that it is Hualin.

"That is really amazing..." The reporter looked at Lu Zhou with surprise. Although she is not a scholar in the academic world, she is a journalist in the science field. She still has a good understanding of the status of this issue in the field of mathematics.

After a pause, the BBC reporter continued to ask: "So, for your other report, we all know that you have proved that the solution to the ns equation exists, and the academic community generally recognizes your proof...but If, I am saying, the proposition is not proven, but is falsified, what impact will it have on our lives?"

The ten fingers crossed on the knees, and the boat on the chair smiled and said with a relaxed tone: "In fact, if this proposition is falsified, the meaning will be even greater. Take the smoothness as an example, if we find it in one At a particular point in time, our equations are no longer smooth, which may mean that we not only solve an unanswered mathematical problem, but also that we have discovered new physics."

Reporter: "Do you feel sorry?"

Lu Zhou sighed: "It's a pity... In fact, when we worked with Professor Fefferman on this topic, we thought we found this special time. The result is regrettable to prove that it is just an illusion."

"What made you discover?"

"When jogging around the lake, as for the more specific ideas..." Lu Zhou looked around and asked, "Is there a blackboard here? If there is, I can explain this question in detail."

Reporter Khan said: "This... no need."

Relevant reports were released on the second day after the interview. After the editing of the bbc science column, interspersed with some fragments of the report, it was considered to restore the original appearance of the interview.

After Lu Zhou saw the news video on the oily soil, he looked at the comment area by the way.

However, unfortunately, foreign netizens seem to be not very interested in the two things of mathematics and learning. The focus of attention is all on Vera.

The most praised comments, the translations are basically "Miss sister is so beautiful!", "Want to organize a group to travel to Ukraine", "Do you have a boyfriend?", "Want to find a girlfriend?" Content.

He admits that trying to overcome the weakness of his heart, Vera, who stood on the stage and bravely made a report, did look at some dazzling. But the place that really deserves attention is not at all these boring things.

It is too superficial!

Shaking his head, Lu Zhou closed the video, and he was ignored by the foreign netizens, and did not want to talk...

......

The core of the International Congress of Mathematicians is still in academic exchanges, and many wonderful papers and reports have indeed emerged during the conference. In all senses, Lu Zhou can be said to have gained a lot in this conference.

After spending a full day in academic exchanges, the nine-day International Congress of Mathematicians finally came to a close in the singing and dancing of a group of South American artists.

After the closing ceremony, the logo of the conference outside the Barra da Tijuca Hotel was withdrawn, and scholars from all over the world took the return flight.

It is worth mentioning that in the end, Bill Carol did not find his lost medal.

However, the organizer held a special award ceremony in a generous manner, and made up for the lost medals. It did not make the conference unrecoverable regret.

"... Rio's law and order is disappointing, and there are even participants who have been robbed on the beach. There is no doubt that this is definitely the worst Icm conference in history. There has never been a theft of the Fields Prize. Things, and even within half an hour just after the award ceremony.” Sitting on the returning plane, Professor Fefferman shook his head.

The South American mathematics community is unique in the direction of the power system, which is headed by Brazil, and this is one of the reasons why this number of conferences chose to be held in Rio de Janeiro.

Although the International Union of Mathematicians had some concerns about the security situation in Rio de Janeiro, I did not expect it to be so serious, and I did not expect such awkward things to happen.

In particular, the attitude of the local police in Rio de Janeiro is even more disappointing.

If it weren’t for the excellent reports in the conference, this session of the icm conference can only be described as bad...

Lu Zhou said with a smile: "Why don't you come to Beijing to hold it? I can guarantee that even if you dig three feet, lost medals will be found."

Of course, Lu Zhou feels that the greater possibility is that the thief will be stared at the time he has not shot, and he will be killed when he reaches out.

After staying outside for so long, except for those friends and family, what most missed him was the domestic security environment.

Professor Fefferman smiled.

"This is a good idea, and I believe that there must be this opportunity in the future!"
