In the auditorium, the presentation continues.

On the podium, Xu Chuan accelerated his explanation.

The paper on the phased proof of the NS equation is more than 200 pages long.

Although most of it is a quotation and a calculation of inferences, there are also a number of key proof processes, which need to be explained at the presentation.

If you don't hurry up and speed up the explanation, I'm afraid I can't finish it in the morning.

As Xu Chuan began to gradually speed up his explanation, in the auditorium, many scholars who came to listen to the report also stared intently at the podium.

After all, the paper and the explanation are two concepts, even for those top bulls in the front row, even if they have read and understood the proof paper, they still have a lot of gains from Xu Chuan's explanation.

In the auditorium, Zhang Wei, Xu Chenyang, and Yun Zhiwei, the golden generation of Peking University, sat together, listening to the report on the stage with serious faces, just like listening to the lectures in class more than ten years ago.

After outlining a knowledge point in the notebook in his hand, Zhang Wei suddenly sighed.

Xu Chenyang and Yun Zhiwei on the side cast puzzled looks.

"I thought I had hope, but I didn't expect to find out today that the gap was so far." Zhang Wei said a nonsensical word, and then stared at the figure on the stage silently.

A nonsensical word, but as friends for many years, Xu Chenyang and Yun Zhiwei know very well what Zhang Wei is talking about.

The three of them are known as the golden generation of Peking University, but the strongest is undoubtedly Zhang Wei.

If Zhang Weidu felt that he was so far away from that person's medal, let alone them.

Sure enough, only the strongest of the strong can win the Fields Medal.

......

On the stage, nearly two hours passed, and Xu Chuan finally began to wrap up.

When the last PPT manuscript came into the eyes of the audience, he didn't need to make any other explanations.

“..... Based on the above, the derivation of the ns equation has come to an end. ”

"Predictably, given a finite space, a three-dimensional incompressible OKES equation smooth solution exists when the initial value is infinitely smooth!"

"Of course, whether the solution of the three-dimensional incompressible OKES equation exists and is smooth in infinite space is still a mystery, which requires more effort and sweat on our part."

"But at least, for now, we have successfully launched a clarion call to charge towards this majestic peak, and we have climbed a long way forward."

"I hope that one day in the future, we can stand on the top of the mountain and harvest a complete answer!"

Xu Chuan's words were clearly transmitted from the stage to every corner of the stage.

The moment the sound fell, everyone in the auditorium couldn't help but stand up, and the warm applause poured like a tide, deafening like thunder, and lasting like a drum.

In the front row of the auditorium, a smile appeared on the face of Peverman, who had come from Princeton.

As he saw earlier, the phased results of the NS equation have been confirmed.

On the other side, Zhang Wei of Peking University also stood up and applauded.

Last year, he made the person in front of him his goal, hoping to catch up one day in the future.

But now that hope seems to be quite slim.

Or rather, it's not that he's not strong enough, it's just that the opponent is too strong.

This is a problem that the mathematical community may take a whole century to solve, if not necessarily.

And the other party has solved one completely, and the other has also solved most of it, only to finally advance it to the infinite three-dimensional space.

Perhaps, the Fields Medal will be awarded twice for him?

After all, no one in history has ever solved two millennial problems, if he could have done it.

Of course, for the person standing on the stage now, even the glory of the Fields Medal will be overshadowed in front of him.

Or rather, the Fields Medal is honored to have his name.

Just as the Nobel Prize is honored by the name Albert Einstein.

.......

The applause lasted for more than half a minute in the auditorium before it subsided slightly.

Waiting for the applause to slow down a little, Xu Chuan left the podium, stood on the edge of the podium, and bowed slightly to the audience to express his gratitude.

Although the report on the phased results of the NS equation has been explained, the report meeting has not ended.

The next part is the key to the presentation.

In a presentation meeting, no matter how good the speaker explains, there will still inevitably be doubts.

In the question session, it is his duty as a reporter to answer the questions raised by his peers one by one.

Whether he can successfully answer all the doubts will also determine whether his paper can be recognized by the entire academic community.

Of course, there is also the most important peer review.

......

Waiting for everyone to re-seat, Xu Chuan then spoke: "The following will be the question time, if you don't understand anything about my paper or the report just now, please feel free to ask, I will do my best to answer." ”

As soon as the words fell, some of the audience raised their hands.

Xu Chuan glanced around and saw a lot of acquaintances, from Tao Zhexuan to Qiu Chengtong, to Martin Hale, to Artur Avila......

Fields Medal winners alone have double-digit numbers in the audience.

Of course, this is also related to the ns equation, which belongs to the field of partial differential equations, and the partial differential equation is now a framework, and anything can be put into it, no matter what analysis you do, you can finally be regarded as doing partial differential equations.

Or it can be said that almost everyone who studies mathematics has been exposed to understanding and can parse partial differential equations, but the depth is different.

The question session consumed a lot more time and asked questions than Xu Chuan imagined.

Not only the big guys in the field of partial differential equations, but also many big names in other fields of mathematics raised their hands.

In addition, many scholars in the field of physics also raised their hands to ask questions and express their doubts.

For the questions raised by these elders, Xu Chuan answered them one by one.

But there were too many people asking questions, and until half past twelve at noon, there were still people in the audience raising their hands in an endless stream.

Backstage, Liu Gaojun, the president of NTU, waited anxiously, and since eleven o'clock, the staff in charge of lunch on the administrative side have come to ask again and again.

But the question session on the front desk side has not yet been completed, and the backstage side has to wait patiently.

"Headmaster, it's half past twelve here."

Backstage, the administrative staff in charge of lunch came over again to urge, after all, it was already noon, and dining was also a big deal.

Liu Gaojun nodded, took a deep breath, and said, "I know." You get ready, and I'll go up and communicate with Professor Xu. ”

It's half past twelve, and there's no other way, even if it's time to postpone the question session.

After all, if you don't eat something to fill your stomach, what should you do if you are hungry and someone has low blood sugar when you are hungry.

Thinking about it, he personally ran to the stage and discussed with Xu Chuan in a whisper, suggesting that the unfinished questions be postponed until the afternoon.

Xu Chuan nodded and agreed to the suggestion.

It's not just the audience and scholars in the audience, he also has to take a break.

From half past eight in the morning to half past twelve, he has been standing on the stage for more than four hours.

After discussing the proposal, Liu Gaojun took over the stage from Xu Chuan, quickly announced an intermission, and invited everyone to the restaurant for dinner.

Xu Chuan walked away from the backstage, avoiding the media reporters who were squatting outside.

Although the interview is unavoidable, it can be said later.

Come once now, and I'll definitely come again after the afternoon question session, trouble. So this kind of thing, if you can do less, you can do less.

Although science does require a certain degree of exposure, at his level, it doesn't matter.

And there was a question session in the afternoon, and his time was precious, so he hurried to eat something and then rest for a while, so he didn't have much time to waste on these media reporters.

If you want to interview or something, you have to wait until the report is completed.

......

For the first time to hold such a world-class report meeting, NTU still adopted the self-service form commonly used in international report meetings, so that you can eat and communicate at the same time.

In the hotel's restaurant, Xu Chuan took the plate, picked some food, and then found a corner to sit down in a low-key manner.

But not long after he sat down, a sharp-eyed scholar noticed him.

After all, he is the protagonist this year, and the dazzling light is dazzling even when he sits in the corner.

"Professor Xu, your presentation just now is really wonderful! It was just perfect! ”

In the corner, a young scholar who noticed this side quickly walked over with a dinner plate and greeted Xu Chuan with a smile on his face.

Hearing the voice, Xu Chuan raised his head and responded with a polite smile: "Thank you." Who are you? ”

"Gacepe López, currently studying with William Timothy Gowers."

The young man quickly signed himself and continued, "Professor Goles told you that he was busy with some things at the moment, and he was sorry that he couldn't come to the meeting, although he would like to. ”

Hearing this familiar name, Xu Chuan's mind suddenly appeared an elegant and handsome old man, the proof paper of the weak Weyl-Berry conjecture was reviewed by him, and among the mathematicians, this is probably the only one who can compare with him.

He smiled and spoke, "It turned out to be a student of Sir Gowers, and it was a pleasure to meet you. Thank you, Mr. Sir for your memorization, and if you have time, I welcome him to come to China for an exchange visit. ”

Gacepe López nodded quickly and said, "I'll tell the professor, besides, what ..... Prof. Xu, can I ask for your contact information? Mailboxes are also available. ”

Xu Chuan nodded with a smile and said, "Of course." ”

"Thank you so much."

After exchanging contact information with the young man in front of him, Xu Chuan continued to eat.

But after a while, someone came to the front again, and this time sat directly in front of him.

"Congratulations, another century of problems solved."

The voice sounded in his ears, Xu Chuan raised his head, and an acquaintance met him.

"Long time no see, Feverman." Xu Chuan smiled and greeted the person sitting across from him with a plate in front of him, who was none other than Princeton's Feverman.

"Yes, it's been almost half a year since you separated in Brazil last year, and it seems that you have been doing well since you returned home, and you have taken a step forward in mathematics. Before, Deligne was worried that you would waste your talent when you returned home. Feverman laughs.

Xu Chuan said with a smile: "It's just a phased achievement, and there is still a long way to go from the top of the mountain." ”

Feverman made an exaggerated expression and teased, "That's it? This is something that many mathematicians will never be able to do in their lifetime. ”

After a pause, he continued, "You're one step ahead of me, and the NS equation is the goal I've been working on. ”

Xu Chuan smiled and said, "It's just lucky, and I also stepped on the shoulders of my predecessors." ”

Peverman: "Why don't we have a competition?" Now it's up to you to figure out who solves the rest of the NS equation first! ”

Although he can be said to be an old man in terms of age, he is not old, he will always maintain his love and challenge for mathematics, and it is rare to meet a like-minded friend in life.

Xu Chuan shook his head with a smile and politely declined this suggestion: "I'm sorry, I may not focus on the NS equation in the next time." ”

“why？”

Feverman looked at Xu Chuan in surprise and confusion, in his opinion, it is necessary to strike while the iron is hot and take advantage of the victory, maybe it is very likely to solve the rest of the ns equation, after all, this should be the most thoughtful time.

Xu Chuan thought for a while and said, "In many ways." ”

"On the one hand, I have a lot of other things to do, such as the collision experiment on inert neutrinos in the second half of the year."

"On the other hand....."

After a pause, Xu Chuan looked at Ffeifferman: "I feel that the NS equation is a difficult problem that I can't solve now." ”

Before Peverman could speak, he continued, "I know what you're trying to say, but I've thought about it, and I don't feel anything. ”

"Even ......., I have a vague feeling that the method of proving the phased results of the NS equation will not work in the future."

Hearing this, Peverman was stunned for a moment, and quickly asked with interest: "What do you say?" ”

Xu Chuan said with a smile: "If you are interested, let's talk about it tomorrow, now I have to fill my stomach first and then go to rest, after all, there is still a question session to pass in the afternoon." ”

........

ps: There is one more chapter in the evening, ask for a monthly pass!
