Xu Yun came back from school with his formalities and documents, and took an international flight to Princeton the next day.

The voyage would take more than ten hours, and Xu Yun had no intention of resting for the time being, so he took out a few pieces of scratch paper and checked them on them.

During this time, most of his energy was spent on the design and implementation of solid-state lidar.

However, he had previously entered a state of overclocking in the brain, which prompted him to have a new idea for the proof of Goldbach's conjecture.

Progress is much faster than before.

Up to now, the process of proving Goldbach's conjecture by using topological group theory has been basically completed.

Yes.

He followed the Hodge conjecture and proved the Goldbach conjecture.

Although I didn't bring the computational manuscript with me, I had the steps in my mind.

According to his plan, when the International Congress of Mathematicians is over, he will officially start writing the paper.

"The results of the argument are correct, and international mathematicians should not find fault with it."

I don't know how long it has been, Xu Yun looked at the scratch paper filled with mathematical formulas he wrote down slowly, exhaled a breath, and whispered softly.

Unlike Hodge's conjecture, which yields a prize, proving Goldbach's conjecture is entirely up to his own level, and some details will inevitably become loopholes in the eyes of others, so he must check and fill in the gaps to ensure that the entire proof process is accepted by international scholars.

Temporarily put down the pen and gently slightly sour eyes, just as I wanted to shout the flight attendant, English sounded in her ears.

"What would you like to drink, sir?"

When he looked up, he saw a blonde foreign stewardess in uniform standing next to him.

"Please give me a glass of water." Xu Yun smiled and replied in English.

When the words reached the ears of the flight attendant, a slight surprise could be clearly seen in her eyes.

She didn't expect Xu Yun's English to be so good.

Even the accent is purer than hers.

"Sir, you speak English very well." When he handed the water to Xu Yun, he took the initiative to praise it.

"Thank you."

Xu Yun took the water and expressed his gratitude.

His oral proficiency had already improved dramatically, and after the last increase in his abilities, he had mastered several major languages just by taking the time to study occasionally.

And no matter what language you use to communicate, it will make you feel very comfortable and happy.

At the moment, it is normal to surprise a flight attendant with just one sentence.

Of course, he didn't have the idea of having an in-depth conversation with the flight attendant, and he continued to argue after he passed.

According to the process of the International Congress of Mathematicians, after the winners of the Fields Medal and other awards are announced on the first day, the winners are required to report on the second day.

As for the content of the report, he had already had a plan in mind.

The last academic presentation held at the Department of Mathematics at Beijing University explained in detail the process of proving Hodge's conjecture.

This time, if you continue to choose the direction of the Hodge conjecture, it will seem a bit old-fashioned.

Therefore, he intends to excerpt the proof process of Goldbach's conjecture and take the opportunity to publish it to the world.

At that time, Perelman directly posted the proof process online, and there was nothing wrong with him doing so.

The only thing to pay attention to is to prevent rollover.

If his proof is disproved by other scholars, the fun will be great.

After all, as a quadrennial event for mathematicians, many of the mathematicians who come to attend are academic authorities.

Fortunately, he is confident in his topological group theory and the proof process.

That's it.

When the time came to the evening, the plane landed safely at the international airport, and the whole trip was very smooth.

……

"Let's contact the pick-up staff from Princeton University first."

Stepping on overseas land for the first time, Xu Yun didn't feel anything, even if he had to take out his mobile phone.

At this moment, out of the corner of his eye, he noticed that a middle-aged foreign man in a black suit was walking towards him quickly, although he did not have a clearer memory point in his mind, but he always had a very familiar feeling, and he was sure that it was someone he knew.

At this point, he stopped for a moment, patiently waiting for the other party to come.

"I finally saw you, Xu Yun."

"The darling of the math world."

"You look younger than I thought you were."

Hearing the other party shout out his name and what he said, a familiar name suddenly appeared in Xu Yun's mind.

It's just that this name surprised him.

"Mr. Hofer?"

As one of the four top journals in mathematics, Hofer serves as the editor-in-chief of the editorial board.

But now the other party came to pick him up in person.

It shows the degree of attention.

"I know you're coming to Princeton University for an exchange, and I've been very happy for the past two days."

"That's why I came here for the opportunity to pick up the airport today."

"I've arranged a hotel for you, and I'll pick you up tomorrow to go to Princeton University for an exchange, and Professor Deligne and Professor Witten are looking forward to it."

Hofer was very enthusiastic and basically arranged for Xu Yun.

Let it quickly adapt to the rhythm here.

It is no exaggeration to say that if someone in the academic world saw this scene at this time, they were afraid that their eyes would be shocked.

In fact, after careful calculation, Xu Yun and Hofer met for the first time, and they communicated through email at most.

Because Xu Yun saw the report of Hofer's interview last time, he felt more familiar.

"Thank you, Mr. Hofer."

Then Xu Yun didn't delay any longer, thanked Hofer and followed him out of the airport and walked outside.

But after seeing the car prepared by Hofer, Rao is calm heart couldn't help but ripple.

Parking in front of him was a Rolls-Royce.

For a luxury car like Rolls-Royce, he can naturally afford to buy the wealth created by deep technology, but unfortunately he himself does not have the spiritual need for this.

To put it simply, they will not pursue luxury cars.

So much so that the company's car distribution is still business-oriented.

He really didn't expect that the first time he rode in a luxury car, it would be in such a special way.

"Get in the car."

"You've been on the plane for so long, you need to go back to the hotel early to rest."

"The driver drove very steadily."

Hofer saw Xu Yun standing next to the car and didn't move for a long time, so he couldn't help but remind him.

As he spoke, he took the initiative to help open the car door.

"Okay."

Xu Yun was interrupted by the voice, nodded with a smile, and decisively sat in the back row of Rolls-Royce.

Immediately after Hofer went up from the other side, the car began to slowly start and drive towards the hotel near Princeton University.

And Hofer in the car finally got the conversation down to business.

"I didn't expect you to be so talented in math and speak foreign languages so well."

"It's hard to imagine that you can learn so much in a limited amount of time."

"Talent coupled with hard work is an essential quality that a true academic researcher should have." Xu Yun had already lost his restraint at this time, and he didn't forget to ask rhetorically while following Hofer's words: "Don't you think that's the case, Mr. Hofer?" ”

"Naturally."

"You're the most gifted genius I've ever met, and you're hardworking at the same time." Hofer chimed in.

After speaking, a smile appeared on the corner of his mouth in the next second, and the words changed.

"As far as I know, you published a lot of papers last year, why is there no news so far this year."

Xu Yun listened to Hofer's words in his ears, and almost didn't need to think to understand that the other party was urging the draft in disguise.

Last year, after his graduation thesis was submitted to the Annals of Mathematics, the publication caused a stir in the number theory community.

Many people are interested in the topological group theory that he mentioned in his paper.

For this reason, Hofer also urged the draft in an interview.

Originally, he had replied in the email that Hofer would submit the article as soon as possible, but he didn't expect it to be delayed due to various factors.

In the second half of this year, the topological group theory paper was even more stillborn.

It's embarrassing to think about it.

I'm afraid that Hofer came to the airport to pick him up in person just because he wanted to urge him to change in person.

The thought stayed here, Xu Yun decided to give the other party some thoughts first, and the right should be a thank you for his pick-up.

"When the mathematicians conference is over, I should have a paper, and it will definitely be published in the Annals of Mathematics."

"Great."

"Could it be that your proposed topological group theory has been successfully proven?"

Hearing the answer he wanted from Xu Yun's mouth, Hofer's face was visibly full of excited smiles.

The Annals of Mathematics is not the only one in the mathematics world, and several other journals are strong competitors.

Whether or not you can ensure your competitiveness depends on the impact of your published papers.

Xu Yun's previous success in proving the Hodge conjecture has made the Annals of Mathematics the most authoritative academic journal, and more valuable papers are needed to maintain it.

It is precisely the topological group theory proposed by Xu Yun that is the most suitable.

Not to mention the heat brought by the number theory community, if you really want to successfully prove it, it is equivalent to promoting the problem of number theory.

In addition, during this period of time, some people in the number theory community also tried to prove the topological group theory proposed by Xu Yun, but the results were never satisfactory, so some people even claimed that this problem was unsolvable.

It is believed that topological group theory cannot succeed.

It is conceivable that if Xu Yun really publishes the complete paper, the influence of the Annals of Mathematics will definitely rise again.

However, Xu Yun's answer next made him feel disappointed.

"It's not topological group theory, but it will have higher academic value than topological group theory."

"New research directions?"

"That's a shame."

When Hofer heard that the paper Xu Yun said was not the topological group theory promised before, the expression on his face instantly became disappointed.

In this regard, Xu Yun temporarily sold a pass, and did not directly state that he had proved Goldbach's conjecture.

Anyway, when the mathematicians' conference opens, they will naturally know.

The rest of the time may be a lack of topic, making the atmosphere in the car seem a little silent.

Fortunately, this situation did not last long, and it didn't take long for Xu Yun to arrive at the hotel arranged by Hofer.

Looking up, a few words immediately popped into my head.

Luxury.

Tall.

What surprised Xu Yun even more was that Hofer also specially arranged a luxurious presidential suite.

Knowing this situation, he suddenly didn't know what to say, and he really didn't expect Hofer to spend such a big amount of money in order to urge the change.
