August 1, 2018.

The 28th International Congress of Mathematics officially opened in Rio de Janeiro, Brazil.

In the hotel room, Xu Chuan stood in front of the bathroom mirror in a suit to tidy up his appearance.

Outside the room, the doorbell rang 'Ding Dong' and 'Ding Dong', as if urging the people inside.

He walked over and opened the door, and there were four of his students standing outside the door.

"Are you ready, Professor? The conference is about to begin. Shahi Perez, a younger student, asked excitedly as she stood in the doorway.

Xu Chuan glanced at the several students who were all looking at him expectantly, and said with a smile: "Let's go." ”

"Professor, is this your first time attending an international mathematical conference?" In the elevator, Sha Xi, who had a lively personality, looked at the calm Xu Chuan curiously and asked.

"Of course it's the first time, what's wrong?" Xu Chuan turned his head and asked.

"But you don't look excited at all, and today is the day of the Fields Medals, don't you look forward to it?"

Xu Chuan smiled and said, "Excitement and anticipation are certain, but it is enough in my heart." ”

"It sounds like a middle-aged man or an old man." Shahi Perez muttered.

On the side, Amelia shrugged her shoulders and said, "If you can also prove a Seven Millennium Problem like the professor, maybe you can understand the professor's state of mind." ”

After a pause, she added: "But you will never be possible in this life, after all, you are twenty-four years old, and the professor proved the Hodge conjecture when he was twenty years old." ”

Hearing this, Shahi immediately stopped talking, which was too shocking.

The corners of Gu Bing and Roger Dean on the side also moved, and they stopped talking.

Amelia's wave of AOE damage is really fatal.

Xu Chuan smiled, did not speak, and walked towards the venue with a few students.

At the age of 20, he proved a millennial conundrum, and he could not have done it without the knowledge of his previous life.

Or to put it another way, probably no one in the world today can do it.

Even if Newton or Gauss were born in this era, they would not necessarily be able to do it.

Of course, he didn't say that he would definitely not be able to do it, only that it was very difficult, almost impossible.

The reason is simple, today's mathematics is no longer the mathematics of the decade.

The sheer volume of mathematical knowledge and the many branches of mathematics make it difficult for today's mathematicians to achieve great results at a young age.

Twenty years old is not even enough for a person to learn everything needed to prove a millennial problem.

This is why Poincarat has been called 'the last mathematical generalist in history' by the mathematical community.

At the beginning of the twentieth century, mathematics was already huge, and it was difficult to understand and study it comprehensively, and then study it in depth.

In the 21st century, after another hundred years, the branches of mathematics are already so large that it is difficult for ordinary people to imagine.

Not to mention the rest, there are more than a dozen major branches of geometry alone.

The algebraic geometry studied by his grandfather, Pope Grothendieck the Elder, was nothing more than a generalization of plane analytic geometry and three-dimensional spatial analytic geometry.

Nowadays, there are far fewer people who can understand all areas of mathematics than wild pandas.

Looking at the entire mathematical community today, Tao Zhexuan is the only one who can have this reputation.

The "comprehensiveness" and "comprehensiveness" of mathematicians are actually a common topic.

If there is no clear standard for this kind of issue, it will be nonsense to discuss.

If the criterion were to be "proficient in (almost) all branches of mathematics at the time, and to have a deep understanding of them," the last person would probably be Poincaré or Hilbert.

If the criterion is to be "not only proficient in (almost) all branches of mathematics of the time, but also extraordinary contributions to (almost) every branch", there is no doubt that neither Hilbert nor Poincarat were qualified.

The last such existence to "fully open up the whole frontier of mathematics" are Euler and Gauss.

Of course, "comprehensiveness" or "synthesis" is not the right way to open up the matter of "evaluating a mathematician"; Because mathematically it is clear that not everything is equally important.

A fair criterion for evaluating a mathematician is how many "important" things he does, not just how many things he does.

Riemann is far inferior to Euler and Gauss in terms of the number, scope, completeness, and length of his career, but he is far from being in a position close to them.

As for Garohua, it is a more extreme example.

In the face of the iron curtain that almost all original ideas were monopolized by Gauss, he relied on pure talent to "step on the southern sky, shatter the sky, and never return", opening up the indispensable group theory and illuminating the new world of abstract algebra.

Although this great mathematician only managed this profession in his career, he still succeeded in this and carried it forward, and the future generations do not know how many people are unknown.

......

Thinking all the way, Xu Chuan soon came to the venue where the International Mathematics Conference was held.

Although there is still more than an hour before the official opening of the conference, the venue is already very lively at this moment.

Mathematicians of all stripes were looking for their familiar friends outside the venue, or the great bulls they hoped to meet.

Inside and outside the venue, a large number of media are preparing to enter the venue under the organization of the staff to shoot and report.

Xu Chuan's arrival soon caused a sensation outside the venue.

People who recognized him crowded around, especially the astronomers and astrophysicists who had already arrived and had been squatting outside the venue. They were the first people to recognize Xu Chuan, and in comparison, scholars in the field of mathematics were much slower to react.

But this is normal, after all, people from the astronomical and astrophysical circles came here to expand the application report of Xu Chuan's xu-weyl-berry theorem.

The noisy situation outside the venue made the media who were originally entering the venue smell an unusual signal, and they didn't bother to enter the venue, so they ran over with their cameras on their shoulders.

Outside the venue, the conference personnel who were organizing work were shocked when they saw this situation, and hurriedly called for help to prevent a crowded stampede.

Surrounded by the crowd in the center, Xu Chuan also had a big head, especially the fanaticism of those astronomers and astrophysicists, which was even more of a headache.

I knew that I would not have agreed to the request of the International Mathematical Union, and there were not so many people coming to the different venues and then holding a separate report meeting.

Many of those who came here today came with the mentality of participating in the mathematics conference together and increasing their knowledge.

Fortunately, it didn't take long to be distressed, and the staff who rushed to hear the news persuaded them to separate the crowd, which allowed Xu Chuan to be freed and enter the venue.

......

Entering the venue, before Xu Chuan could sit down, someone came over again.

This time, it was a media reporter, and he was familiar with it.

"Hello, Professor Xu Chuan." The beautiful reporter with a delicate face greeted Xu Chuan in her voice like a yellow bird.

Seeing the person standing in front of him, Xu Chuan was stunned for a moment, and then greeted with a smile: "Hello, Reporter Sun, long time no see." ”

The figure in front of him is Sun Yutong, a CTV reporter who interviewed him at the Kraford Awards ceremony last year.

Hearing this, Sun Yutong was also stunned for a moment, and then a bright smile appeared on his face: "I didn't expect you to remember me." ”

Xu Chuan smiled and said, "I think my memory should be okay." ”

Sun Yutong smiled, and then said: "That's the case, Professor Xu Chuan, we CTV have applied to the International Mathematical Union for the live broadcast authorization of this mathematics conference, and while the conference has not started yet, I would like to ask you to say hello to the domestic audience, I don't know if it is inconvenient for you." ”

With a request, she quickly added, "Of course, the camera isn't on you right now, and our conversation isn't recorded in the live room, so if it's inconvenient for you, we can cancel the process without any problems." ”

Hearing this, Xu Chuan was a little surprised, CTV applied to IMU for the live broadcast rights of the conference, which is a rare thing.

But he also knew why, so he nodded and agreed to the request.

The country really bet heavily on him this time.

In the past, there has never been a live broadcast of CTV, even the one held in China in 2002, which has never been broadcast live to the whole people.

Of course, this also has something to do with the fact that the Internet in China was not fully popularized at that time.

But with the number of people in China, coupled with the particularity of CTV media, coupled with official publicity, if you start a live broadcast, there are at least five or six million people, and if you are more, tens of millions of people are normal.

With so many people watching, if he fails to win the Fields Medal at this conference, he will lose face.

However, the International Mathematical Union Committee could not have done so, and a top scholar who had demonstrated the seven millennial problems did not win the Fields Medal, thus invalidating the credibility of the medal.

Who will think that the Fields Medal is the highest honor in mathematics in the future? I'm afraid no one thinks so, and even the many mathematicians in the field of mathematics themselves will not pursue this medal anymore.

Hearing Xu Chuan's agreement, Sun Yutong also breathed a sigh of relief, and quickly said with a smile: "Wait a minute, I'll let people come over." ”

After that, he trotted over and called the camera brother.

After a while, the little brother with the camera on his shoulder trotted over.

"Hello everyone, before the opening of this mathematics conference, we are honored to invite the young mathematician Professor Xu Chuan."

Standing beside Xu Chuan, Sun Yutong looked at the camera with a smile with a strong affinity, and after saying hello to the audience in the CTV live broadcast room, he quickly moved out of the C position and let Xu Chuan stand in the center.

"Hello everyone, I am Xu Chuan, a tour guide, and welcome everyone to watch this International Mathematical Conference."

Looking at the camera, Xu Chuan smiled and said hello to the audience in the live broadcast room and made a joke.

And with his entry, the live broadcast room of CTV instantly went crazy. In the live broadcast room where you can't brush gifts, what you can brush is the barrage.

For a while, the barrage in the live broadcast room surged like a tide.

[, it's the god of Sichuan! ] 】

[The elder with his own golden light! ] 】

[The god of Sichuan is awesome! Broken Voice! 】

[Take a bite of the wisdom of the Sichuan God, I just ask that the high generation will not make up the exam this semester! ] 】

[Kawajin won the Fei Award this time, right? ] 】

[Definitely, Hodge's conjecture has been solved, if the Fei Award doesn't have him, I'll still see a p.] 】

[Chuanshen's voice is so warm, I love it, I really want to give Chuanshen a monkey. 】

[Hehe, witty as me, I have applied to the Department of Mathematics of NTU after the college entrance examination this year, and I can be an alumnus with Chuanshen in one month! ] 】

The barrage in the live broadcast room was crazy, but Xu Chuan couldn't see it, under the leadership of Sun Yutong, the two exchanged a few simple questions, and quickly ended the conversation.

On the one hand, even if there is a live broadcast authorization, CTV will not be able to disturb Xu Chuan for too long, and it is already good to ask him to show his face before the opening.

On the other hand, the Fields Medal has not yet been awarded, and some questions are not easy to ask.

Of course, the more important thing is that the math conference is about to begin, and they have to go back to their places to record the next precious award ceremony.

......

With the mathematicians and astronomers participating in the Mathematics Congress, the 28th International Mathematical Congress officially kicked off.

At nine o'clock, the conference officially began.

Marcelo, the director of the Organizing Committee of the Congress? Professor Viana began with his opening remarks.

He also thanked the local organizations and sponsors of the conference, and thanked the new and old friends who came to attend the conference, and announced the opening of the 28th International Congress of Mathematics.

Subsequently, Professor Shigefumi Mori, President of the International Mathematical Union and Fields Medal winner, delivered a speech and reviewed the development of the mathematical community in the past four years.

After the two hosts finished their speeches, the opening ceremony of the next Mathematics Conference entered the most exciting part--- "Announcing and awarding the four major awards of the International Mathematical Union." ”

The first to be announced was the Gauss Prize, which in 2018 was awarded to Stanford University professor David Donohue; The award was given "for his fundamental contributions to the mathematical, statistical, and computational analysis of important problems in signal processing." ”

The Chern Prize was awarded to Mathematician Masaki Kashiwahara of the small island nation for his outstanding and fundamental contributions to algebraic analysis and representation theory over the past 50 years.

The Naivan Linna Prize was awarded to Turkish mathematician Ali Neshin for his outstanding contribution to influencing the Turkish public and helping them to raise awareness of mathematics.

According to the International Mathematical Union, Professor Nehin has worked tirelessly to create "math villages" with the intention of providing a peaceful place for all to educate and discover mathematics, which is of great significance to developing countries.

When the three awards have been awarded, the rest is the top priority of this International Mathematical Congress, which is known as the 'Fields Medal' of the Nobel Prize in mathematics.
