Just when the person in charge was busy preparing a new whiteboard for Lin Yu, the time finally came to one o'clock.

"Jingle bell, jingle bell..."

As the crisp bell rang in the lecture hall, everyone slowly retreated from their focused flow state.

This is the bell that rings automatically in the lecture hall after each presentation.

At the same time, it also means that this morning's presentation will officially end.

And just after the bell rang, Lin Yu on the stage also happened to fill the free space of this last whiteboard.

"Given an initial velocity v0(x) and a finite time t that varies according to v0(x), the Navier-Stokes equation has a smooth solution in the range of r×(0,t)......"

"That is, the Neville-Stokes problem in two-dimensional space has a smooth and globally defined solution, and the conclusion is valid!"

After writing this conclusion, Lin Yu also recovered from the state of flow.

He looked around and found that eleven five-meter-long whiteboards had been neatly placed on the lecture table at this time, and even the free space was already very small.

It can be said that with the current situation on the reporting table, there is no longer a special tabula rasa.

Seeing this, Lin Yu looked at the clock hanging in the center again, and found that it was already past one o'clock at this time, and there was still more than an hour before the plane took off.

"Ladies and gentlemen, I think I've found a general solution to the Navier-Stokes equation in two-dimensional space."

Without much thought, Lin Yu turned off his superbrain, then turned around, glanced at the people in the audience, smiled slightly, and said: "As for the general solution of the final Navier-Stokes equation in three-dimensional space, I think that if there is time and opportunity in the future, I will continue to try, so this is the end of my report, thank you." ”

As for the solution of the Navier-Stokes equation, Lin Yu has not yet fully proved it.

He's halfway there, though.

Of course, it's not that he can't fully prove the Navier-Stokes equation, it's that time is running out.

Because just two hours is not enough time for him to fully prove the entire solution of the Navier-Stokes equation.

You must know that even the complete verification process of the Riemann conjecture took Lin Yu about five or six hours.

Therefore, it is simply impossible to solve all of these global problems in two hours.

After all, among the world's seven millennial problems, any random problem represents the top problem encountered by human civilization in a certain field.

Solving any of them will be enough to make a big step forward in the development of human civilization.

Therefore, as long as one problem is solved, it can enable any world power to go to the forefront of all developed countries directly in a certain top field.

"Oh, no! Mrlin, I don't think there's a better place to prove the solution of the Navier-Stokes equation than at the presentation. ”

As soon as Lin Yu's words were finished, Deligne in the front row stood up directly, holding the microphone in his hand, and looked at Lin Yu with sincere and fiery eyes: "Although your report meeting is over, I think everyone here is very willing to witness the moment when the Navier-Stokes equation is fully proved with you!" ”

Speaking of this, Deligne turned around, looked around, and shouted loudly with a fanatical expression: "So, ladies and gentlemen, please tell Mrlin out loud that you would like to witness the moment when the Navier-Stokes equation is fully proved today!?" ”

"Of course!"

"Yes, it's just amazing!"

"I think it's going to be historic!"

"Keep proving it, we all want to know the final answer."

"That's right, I'm willing to dedicate my time to the third talk in the afternoon, and I hope that Mrlin can continue to verify the complete general solution of the final Navier-Stokes equation!"

………

As Deligne's voice resounded throughout the lecture hall, the originally quiet lecture hall also boiled instantly.

All the mathematicians said that Lin Yu should continue to deduce the final general solution of the Navier-Stokes equation.

For this reason, they are willing to give up the time they should have eaten and rested to witness this scene that will go down in the history of mathematics.

Even if they can't understand the verification process and the final result, they are still willing to share this moment of honor with Lin Yu!

"Thank you for your kindness, but I'm sorry, I don't think I have time to continue here to prove the final solution of the Navier-Stokes equation."

After seeing the scene in front of him, Lin Yu also said apologetically, and then explained: "In about an hour, the plane from Princeton to Huaxia Modu Hongqiao Airport will take off, and I must take my students back to China before the plane takes off." ”

"Because it is now in China, it is the early morning of the New Year's Day on January 1, so I have to take this flight back to China, only in this way, I can arrive safely in the evening of January 1, and then accompany my wife to spend New Year's Day together."

"I think you should be well aware of the importance of the annual New Year's Day."

At the end of the words, Lin Yu looked at all the Mi people in the audience with a smile on his face.

The New Year's Day of the people of the United States is the New Year, and it is the main festival that is unanimously celebrated in all states of the United States.

The most lively thing for the Chinese people to celebrate the New Year is the night before the New Year, that is, tonight.

When the time comes, people will gather in churches, streets, or squares to sing, pray, bless, confess, and welcome the moment of renewal.

At 12 midnight, church bells rang in unison and bands played nostalgic songs.

In the sound of music, excited people will hug each other, with the sentiment of goodbye and the yearning for a new life.

It can be said that New Year's Day is very important to the people of the United States, just like the Chinese New Year's Eve of the lunar calendar, which is very formal and lively.

Therefore, when Lin Yu finished talking about his reasons, all the Mi people in the entire report hall also subconsciously raised a bright smile.

"Alright, Mrlin, we respect your choice."

Seeing this, Deligne couldn't help but sigh lightly, and said with deep regret in his tone: "It's a pity that we can't see the scene where the Navier-Stokes equation is fully proven today. ”

As he spoke, Deligne's eyes were firmly fixed on Lin Yu, and he shouted loudly with a fanatical expression: "However, although we can't see this historic scene today, I believe that in the near future, we will definitely be able to see with our own eyes Mr Lin, when you completely prove the Navier-Stokes equation!" ”

When the words fell, Farjans next to him couldn't help but stand up and applaud hard.

"Bang Bang Bang ......"

And with the applause of Faljans, in an instant, the enthusiastic applause suddenly spread from the first row to the last row.

Soon, everyone in the entire lecture hall stood up and gave the warmest applause to Lin Yu, who was surrounded by eleven special whiteboards on the lecture platform.

For a moment, the entire lecture hall was filled with thunderous applause.

At this moment, the whole Princeton was boiling!

Lin Yu's report is over, and what awaits him will be the verification of the entire mathematical community for half a year, or even longer.

It can be said that as long as Lin Yu's verification process does not have any mistakes.

In addition, he will be able to successfully prove the final general solution of the Navier-Stokes equation in the future.

In the future, his status in the modern mathematics community will be the same as the status of the four major mathematical giants such as Euler and Gauss in the mathematics world!

The reason is very simple, because the Navier-Stokes equation, one of the world's seven millennial problems that have plagued human civilization for hundreds of years, will be gently wiped away by Lin Yu in the near future!

In the lively applause, Lin Yu bowed slightly and left the report table.

"Good boy, you can be regarded as giving us a long face for Huaxia today." Looking at Lin Yu who came over, the old man Chern showed a relieved smile on his face.

In today's presentation, Lin Yu not only wrote a new sieve method, but also successfully proved the general solution of the Navier-Stokes equation in two-dimensional space.

This can be said to be a double happiness for the two old men!

"That's right, from today onwards, we Huaxia can finally puff up our chests and answer Qian Xuesen's previous questions in a dignified manner." The old man Qiu Chengtong next to him also said proudly.

Qian Xuesen's question is a question raised by Qian Lao when the chief visited Qian Lao at the beginning of the 21st century in China.

"After so many years of training, there is no academic achievement that can be compared with the masters cultivated during the Republic of China, why does our school always fail to cultivate outstanding talents?"

It can be said that since Qian Lao's question was raised, the situation in Huaxia in the mathematical community has been somewhat sluggish.

The reason is simple, because they lack exceptional talent.

However, now the appearance of Lin Yu has completely made up for this vacancy!

"It's okay, it's just a normal performance."

Facing the praise of the two old men, Lin Yu smiled modestly, immediately looked at the time that had been half past one, and said: "Let's go, it's not too early, if you don't catch the plane, it will be over." ”

With that, he took the lead and walked quickly outside.

Seeing this, the two old men couldn't help but glance at each other, and after smiling helplessly, they also followed quickly.

Because of the planned plan in advance, Lin Yu's luggage had already been prepared.

Therefore, they only need to get back to the Princeton Hotel, where they can take the prepared bus directly to the airport.

It's just that before Lin Yu and the others walked out of Princeton University, a group of math bigwigs from the Princeton Department of Mathematics caught up.

"Mrlin, I don't know if you remember our previous agreement." Walking in front of Lin Yu, Deligne said with a serious expression.

Conventions?

What conventions?

Lin Yu was confused, when did he have an agreement with Delinee?

As if seeing Lin Yu's doubts, Deligne smiled helplessly and said, "Have you forgotten that I told you that if you perform well in the report meeting, I will join all the professors in the Princeton Department of Mathematics to nominate you for the Crawford Prize?" ”

"Uh......"

Hearing this, Lin Yu suddenly had a knowing smile on his face.

He thought it was some kind of agreement, but it turned out to be this thing.

To be honest, at that time, he thought that Deligne was also joking like him, but he didn't expect him to say the truth.

"Thank you for your kindness, Professor Deligne, but I think it might be better to leave the nomination for the Crawford Prize to someone who comes after me." Lin Yu thought about it carefully, and finally said politely.

After returning to China, his energy should be focused on the first-generation planetary-level civilization mecha, and he will rarely have the time and energy to be busy with other things.

Even in math, there should be no such thing.

Not to mention spending time and energy to go to Sweden in person, and then go out of his way to get the 4.4 million yuan and the certificate.

This is simply a thankless task for Lin Yu, who is not bad for money and honor, and it is completely unnecessary.

"No, Mrlin, although I know that you may not be bad for the money and honor, but the agreement is the agreement, whether you accept it or not, whether the final result is successful or not, I will fulfill my promise." After hearing Lin Yu's words, Deligne said with a serious expression.

"That's right, young man, just by your performance today, you are enough to be nominated for the Crawford Award."

"Yes, not only that, but we will also nominate you for the next Fields Medal."

"Although the general solution of the Navier-Stokes equation in today's two-dimensional space is enough to nominate for the Fields Medal, if you can find the final solution in three-dimensional space, then the next International Congress of Mathematicians will be unprecedented and the most lively!"

"Oh! Rafe, you're absolutely right! ”

………

Just as Deligne finished speaking, the math bigwigs next to him were also discussing.

And listening to everyone's words, the corners of the mouths of the two old men, Chern Shiingshen and Qiu Chengtong, couldn't help but raise a smug arc.

The Fields Medal is an international mathematics award established by Canadian mathematician John Charles Fields.

First awarded in 1936, it is awarded every four years and is often regarded as the Nobel Prize in mathematics.

It holds an award ceremony at the International Congress of Mathematicians of the International Mathematical Union, and awards are given to two to four young mathematicians who have made outstanding contributions at each time.

Winners must be under the age of 40 by New Year's Day of that year.

Each person will receive a prize of 70,000 RMB and a gold medal.

Of course, although its rewards are few, the meaning and honor it represents are supreme!

Even, in a sense, the Fields Medal is more difficult than the Nobel Prize!

"Well, then thank you, Professor Deligne and the professors."

Looking at these stubborn old men in front of him, Lin Yu also said with a smile.

"Nothing, that's what I'm supposed to do."

Deligne waved his hand, and immediately seemed to remember something, and looked at Lin Yu with burning eyes: "Mrlin, I know that you will not stay in Princeton, but as long as you want, we can give you the honor of Princeton Guest Professor." ”

As the name suggests, a guest professor is a scholar hired by "Keqing", and he is a person who comes to give reports or give lectures from time to time.

It can be not a professor, but a celebrity, an official, an entrepreneur, an inventor, and so on.

It can be said that as long as Lin Yu agrees, then there will soon be a professor's contract and it will be sent to Lin Yu.

And these five words of Professor Princeton are full of great temptation for any mathematician!

But it's a pity that Lin Yu is just an amateur mathematician.

"I'm sorry, I don't have any thoughts of going abroad for the time being, and I don't think I will ever have one." Lin Yu shook his head and refused without hesitation.

"Alas......"

Seeing Lin Yu's ruthless refusal again, Deligne also sighed helplessly under the funny eyes of many math bigwigs, and waved his hand: "Okay, whatever you want, if you change your mind in the future, you can contact me at any time, you have to remember that the door to Princeton is always open for you." ”

"Well, I will."

This time, Lin Yu did not refuse Deligne's kindness, but nodded heavily and said with a serious expression.
