In total, the presentation lasted almost an hour and a half.

Of course, even after it was over, almost everyone in the audience did not leave.

After all, for the mathematical community, such a historic event, even if it ends, can still make everyone linger.

Everyone congratulated Li Mu on the stage.

In any case, judging from Li Mu's report alone, his proof could not find any problems at all.

Of course, for a major problem such as the millennial problem, it is impossible to be too rigorous, so probably in the future, the mathematical community will definitely focus on Li Mu's proof, down to the number and symbol.

However, for now, no one will think about this kind of future thing, not to mention, with Li Mu's past proof, will he really make a mistake?

Those fans who regard him as an idol will definitely not think so - and there are many such fans.

There are so many people in the scene, and at least more than half of them are his fans.

Just like Grothendieck back then, almost the entire mathematical community is his fan, and probably, Li Mu's age is poor.

"Congratulations, Li Mu, if it is confirmed by the mathematical community that there is no problem in the future, then you have solved an unsolved problem for the mathematical community and the physics community."

Deligne gave applause to Li Mu, who walked to the audience, and at the same time did not hesitate to send his appreciation.

Wiles also sighed: "I think back to the first time I met you, it was still at the joint mathematics conference, and at that time, you just proved the hail conjecture, but I didn't expect that so many years have passed...... Alas, it's incredible. ”

"'Just proving the hail conjecture'? Wiles, you've been with Li Mu for too long, and your vision has become a little too 'broad'. ”

Hearing Wiles's words, Drinne rolled his eyes and said angrily.

Wileston was dumbfounded.

Indeed, after staying with Li Mu for a long time, his vision did become a little too "broad".

To a certain extent, the hail conjecture that Li Mu first proved was nothing compared to his later achievements.

"Li Mu, congratulations, if nothing else, you will become the second mathematician in the world to successfully prove the millennial mathematical problem."

Everyone smiled and nodded.

"Thank you."

In the face of everyone's congratulations, Li Mu also expressed his gratitude, but at this time, he suddenly noticed a figure.

"Mr. Perelman!"

He shook his hand at the figure.

Everyone turned their heads to see that it was the world's first mathematician to prove the millennial mathematical problem, Gregory Perelman.

At this time, Perelman was walking towards the exit, apparently because the report was over, and he was going to leave.

It's just Li Mu's voice that made him stop.

Turning his head to look over, after a moment of hesitation, this great mathematician, who had been separated from the mathematical world, actually walked over.

Everyone was a little surprised, but then, everyone estimated that it was probably Li Mu's past achievements and his ability that made even Perelman willing to change his attitude for it, right?

Perelman, who has a big beard, looks like a strong man, but in fact his body is still relatively thin.

After walking over, he didn't look at the others, just stared at Li Mu alone, and asked, "Is there something wrong?" ”

Li Mu: "Uh......"

He really didn't know what he was going to ask, and he called him just because he wanted to get to know the former boss.

"If there's nothing to do, then I'll go first." Perelman said, and then he was about to turn away, but halfway through his body, he stopped and said, "Oh, yes, your proof is wonderful, you are a very good mathematician, I wish you success in the end." ”

Everyone was a little surprised, but they didn't expect Perelman to not only say so many words, but also express his appreciation, which is really a bit surprising.

Li Mu said at this time: "Thank you, Mr. Perelman. ”

"Actually, I mainly want to get to know you and discuss the math side of things."

“我在本届大会之前去过圣彼得堡国立大学，博洛尼科夫院长说你其实一直都在研究数学。”

Perelman glanced at the others, then said, "You can come to my house and discuss with me later, now I need to leave first." ”

Then, without saying anything else, he left the place directly.

It's just that for the other people present, Perelman actually invited Li Mu to his house to discuss, which directly surprised them.

"Perelman actually invited you to his house! It's really the sun hitting the west and coming out! ”

Wiles' eyes widened, and he said a Chinese colloquial saying in English, which made Li Mu feel weird.

And the other people next to him were also surprised by Perelman's invitation, and in the end they could only sigh that it was not that Perelman didn't want to deal with them, it was their ability that they couldn't make Perelman make an exception for them.

And Li Mu's ability ......

Putting aside the other conjectures he has proved before, let's not talk about the existence and smoothness of the solution of the Neville-Stokes equation that we have proved today.

From the initial internalization of the space by the external force source, and then by rewriting the Boltzmann equation, and then establishing the integral space, and finally solving the explosion time problem in the NS equation, and finally completing the proof.

This whole process was done by Li Mu alone, and it was not like Perelman who used Richard Hamilton's Rich flow in proving Poincaré's conjecture.

When Richstream was first born, the mathematical community knew that this tool was very important in proving the Poincaré conjecture, and it was proved in the end.

So, to some extent, the proof of Poincaré's conjecture was finally completed by the joint efforts of many people in the mathematical community.

The proof of the existence and smoothness of the solution of the NS equation was almost entirely completed by Li Mu alone.

Such mathematical ability......

Although no one will openly admit it, they all know in their hearts that this young man's ability has surpassed that of each and every one of them.

【数学最难问题之一，已被破解！ 】

All kinds of news spread all over the world.

Professional stuff generally doesn't attract much attention, but if you add the words "the hardest", it suddenly becomes a gimmick.

All of a sudden, all kinds of media around the world began to report on this matter, and even some media close to lace news also reported on this matter, so that the readers of these lace news were very surprised that the newspaper they read would report such a tall thing, and the sun really came out in the west.

Of course, compared with foreign countries, China is even more crazy at home.

Nine days ago, Li Mu's popularity of winning the Fields Medal had not completely subsided, and now he actually proved such an important mathematical conjecture, which made domestic netizens not crazy?

顿时间，什么微博、贴吧、知乎之类的平台热搜榜上，关于这件事情的话题都直接登上了榜首。

On video sites like station b, the top two on the hot search list are also related to it, one is the live video of Li Mu winning the Fields Medal, and the other is Li Mu's three reports.

And CCTV News also published relevant news specifically on this matter.

[In three-dimensional space and time, given a starting velocity field, there is a one-vector velocity field and a pure pressure field, which are the solutions of the Neville-Stokes equation, in which the velocity field and the pressure field need to meet the characteristics of smoothness and global definition.

This is a complete statement of the existence and smoothness of the solution of the Neville-Stokes equation among the seven mathematical puzzles of the millennium.

The Neville-Stokes equation is the most important mathematical tool of fluid mechanics, and it is also the main research object, fluid mechanics exists in all aspects of life, whether it is aerospace or ship engineering, and even in the practical application of water pipelines, etc., the Neville-Stokes equation can be seen everywhere.

If it can be proved that there is a smooth solution to the Neville-Stokes equation, it will be of great help to the research of relevant researchers, because it will lead to a deeper understanding of how fluids move.

However, since the invention of the Neville-Stokes equation in the 19th century, this problem has been present in academia and has not been solved for a hundred years, and research on this problem has been difficult to make progress in academia.

Until this year, China's famous mathematician, physicist, Professor Li Mu through the creation of the external force source internalization space (the academic community generally calls it Lee's space), and after the space to improve, and finally completed the proof, although the proof process is rigorous and flawless, still to be verified by the mathematical community, but in terms of the current general evaluation of the mathematical community, mathematicians are basically optimistic about Li Mu's proof. 】

Then at the bottom of this article, there are also a few photos taken by CCTV reporters at the scene, which were taken by the three CCTV reporters in Russia.

And at the end, there's even a video of them interviewing several famous mathematicians.

This included an interview with Faltins.

In the video, Tu Chengyu, the director of the Russian correspondent station, asked Xiang Faltins: "Hello Professor Faltins, I first want to ask, what is the status of the existence and smoothness of the solution of the NS equation in the academic world?" ”

Hearing this, Faltins smiled: "I think there have been many people who have explained this in the past. ”

"Maybe you don't know too well what criteria the Seven Millennium Math Problems were based on."

"Strictly speaking, these seven problems are the seven most difficult problems faced by the mathematical community, and their solutions will have a very great impact on related fields, just like the significance of the NS equation for the application of fluid mechanics."

At the same time, the Nobel laureate in physics, Feynman, once said that the NS equation is the last problem of classical physics, which is even more important for the academic community. ”

"All in all, the place of this issue in academia is, in the simplest terms, irreplaceable."

The math master's answer made Tu Chengyu nod again and again: "Thank you!" So, what do you think of the second question, Professor Li Mu's proof? ”

Faltingston smiled: "What I don't think is important, but what is recognized by the mathematical community is important." ”

“但我想说的是，李牧是我认为这个世界上最好的数学家之一，他的证明，我一直都十分喜欢反复欣赏。”

"Mathematics is a realist science, and his proof can also make me feel that kind of real wonderful."

Tu Chengyu laughed, "Although I can't read it, I can really see that his proof is wonderful." ”

"Really?"

法尔廷斯笑了笑，“那就很好了。 ”

“那么，最后一个问题，最近我们能够在舆论界以及网络上，看到一些评价说，李牧是有史以来最优秀的数学家，请问您对这件事情有什么看法呢？ ”

This question caused Faltins to fall silent for a moment.

The question of whether it is the "best" is never so simple to be judged.

However, Faltins eventually gave an answer: "I will give this answer before I die." ”

"Of course, when I leave this world, with Li Mu's achievements at that time, I think I will give a positive answer."

"He's the best."

Faltins was a strict man, and rarely praised a person publicly, and now, he has such a high opinion of Li Mu, and he is still "the best in history", which can be said to be extremely rare.

Surprisingly, however, no one in the mathematical community has criticized this.

After all, no one knows that by the day of Faltins' death decades later, how many more great results Li Mu would have made than prove the NS equation, or even greater than that?

……

Compared with the hot theories of the outside world, Li Mu, who is in the center of public opinion, is particularly leisurely because of the complete conclusion of the International Congress of Mathematicians.

On such a big occasion as the International Congress of Mathematicians, it is indeed quite tiring to hold three presentations in a row, except for the first two sessions that are an hour, and the third session is even an hour and a half long.

After three and a half hours on stage at an international congress of mathematicians, it is estimated that Carlos Kenig, president of the International Mathematical Union, and Provsky, chairman of the organizing committee of this conference, did not stay on the stage for long.

Holding a mobile phone, swiping through various group chats.

In the past few days, basically as long as he is in the group, he has posted news similar to [This year's Fields Medal winners list has come out, I am very relieved, there is a person in this group who is ...... in the list of winners].

Who let him really win the award?

Even his college and high school classes didn't know where to attract a bunch of people to join.

Shaking his head with a smirk, he nodded again.

"Look at Weibo again. ”

When you enter Weibo, it's even more explosive.

Looking at those enthusiastic netizens, he touched his face, then took the Fields Medal medal from the side, took a group photo with it in his hand, and then posted a Weibo message.

[I was invited by the International Congress of Mathematicians, I came here to give a few reports, proved a math problem, and won a prize by the way, which is really enthusiastic. 】

After sending it out, it didn't take long for the background comments to reply, as well as the message notification of likes and forwards, which immediately rose rapidly.

99+？

999+！

[Faun, how did you say such a powerful paragraph in such a calm tone. 】

[Okay, good, so pretending to be forced, right? ] Won't I kneel for you? 】

[I'm a student, can you give me this medal?] I hope you don't know what to do. 】

[Your medal is fake, please mail it to me, I'll handle it for you for free]

[I grass, this is the medal of the Fields Medal?] 】

[Got a math problem? The Big 7 Math Problems: Is this a math problem for you? I also won a prize...... MD, the god of faun has to be the god of faun]

[Faun, how can I be as awesome as you? 】

……

Looking at the replies of sand sculpture netizens, Li Mu shook his head with a smile, and then replied under the last comment: [Read more books and read more newspapers, eat less snacks and sleep more. 】

After replying, he looked at the time.

"It's time to visit Perelman."

Then he got up and left the hotel.
