A candid photo caused quite a stir on NTU's campus website.

So much so that in the afternoon of the next day, the class groups and small groups in Xu Chuan's mobile phone exploded, and he was stunned when he saw all kinds of Aite news.

"@徐川, Chuanshen, I heard that your old man has returned to China? Please give a testimonial to prove the Weyl-Berry conjecture! ””

"@徐川, Brother Chuan, who is my sister-in-law? When will you bring it to us and show it? ”

"What about the candy, what about the red envelope? Brother Chuan, don't you have some candy and red envelopes, are you still a person? ”

Xu Chuan: ????

What's the situation? I'm in love? How I don't know myself.

Looking at the 99+ messages in the class group, Xu Chuan sent a few question marks and a message with a confused face.

Well, the whole class group instantly became lively.

", Brother Chuan! It's a living Brother Chuan! ”

"Alive, alive!"

"Sigh, record history! This is the fourth time that Brother Chuan has spoken in the group since the beginning of school. ”

"Brother Chuan, don't deny it, the whole school knows about your love affair now, don't believe it (picture)"

With a sticker in the group, Xu Chuan finally knew why so many people in the class group suddenly gave him a treat.

It turned out that he and his senior sister were eating in the yellow stewed chicken restaurant last night and were photographed, and it is estimated that it was also uploaded to the campus Internet.

"I'm not in love, it's just a senior sister inviting guests to dinner."

Xu Chuan shook his head and explained, isn't it just a meal, this group of people is so exaggerated.

Although the senior sister is indeed one of his rare female friends, he has never thought about such a thing as falling in love now.

There are still so many problems in the mathematics and physics world waiting for him to solve, how can he have time to fall in love.

As he came forward to explain, the turmoil of love subsided in the class group, and everyone's attention gradually shifted to the Weyl-Berry conjecture he had proved.

After chatting about gags in the class group for a while, Xu Chuan put down his mobile phone, and some of the papers and materials on the computer had been downloaded.

Connected to the printer he bought, he printed out this part of the paper.

Although he can read it on a computer, he still prefers to read it with paper in his hand, which gives him a heavy sense of weight after the knowledge is realized.

And he has a habit of keeping every book he has read and some very important materials, including some manuscripts.

In his previous life, he had a storage room of more than forty square meters, which was full of bookshelves and books of all kinds.

From physics books to material books, to mathematics, music, and some cultural books that have been circulated in China, such as ceramics, tea and other ancient cultural books, he has collected and flipped through them.

After all, those things were one of the few ways he could get to know his homeland during the time he was locked down in that country.

.......

When Xu Chuan returned to campus, his occasional appearance in the library and classrooms caused a few sensations, and the rest of the time slowly calmed down.

Although every time he appears outside, it still causes heated discussions, but at least it is no longer a sensation, and NTU students are gradually getting used to this great god who will randomly drop in the school library, cafeteria, or classroom.

Sometimes I even bet on whether the great god will come to math class and physics class or something like that today.

The days passed like this, and in the blink of an eye, the time came to the beginning of March.

In the dormitory, but Xu Chuan was talking about the 'mystery of the proton radius' when his tutor Chen Zhengping called his mobile phone.

"Hey, Xu Chuan, are you busy? If you're not busy, come to my office, there's good news. ”

On the other end of the phone, Chen Zhengping smiled mysteriously, and he didn't know what the good news was.

"Well, okay, I'll be right here."

Xu Chuan answered, grabbed the coat on the chair and went out.

Maybe it's because of the weather, but at the beginning of March this year, the temperature was much cooler than usual, so that the woolen sweater that could be taken off at this time in previous years is still worn on the body, and if you want to go out, you have to wear a thicker jacket.

All the way to Chen Zhengping's office, Xu Chuan knocked on the door.

"Come in."

Pushing open the door, the figures in the office came into Xu Chuan's eyes, not only his mentor Chen Zhengping, but also the deans of the School of Mathematics, Rong Zhizhuan and Professor Zhou Hai.

"Xu Chuan is here, come, come and sit."

Before Chen Zhengping could speak, Dean Rong Zhizhuan greeted him warmly.

"Good tutor, good dean, good Professor Zhou." Xu Chuan said hello in turn, thanked him, and took the chair handed over by Rong Zhi.

"Look at this."

Zhang Weiping smiled and handed over a document, Xu Chuan glanced at it, it was a list of winners.

"The list of winners of the Morningstar Prize in Mathematics? Why is it coming out now? ”

Glancing at the document in his hand, Xu Chuan asked curiously.

The Morningside Prize in Mathematics was established in 1998 by Chengtong Yau, Chairman of the World Congress of Chinese Mathematicians, and Ronnie Chan, founder of the Morningside Group.

Known as the "Chinese Fields Medal", the award is open to Chinese mathematicians under the age of 45 who have made outstanding achievements in basic, applied and computational mathematics.

Once every three years, the awards are divided into gold and silver awards, with prizes of US$25,000 and US$10,000 respectively.

The judging panel consisted of Harvard University professor and Chinese mathematician Yau Chengtong and eight other top non-Chinese mathematicians.

He had won this award in his previous life, and he knew that the award was presented at the end of July and the beginning of August of the award year, and now it is only March, and the list of winners has already arrived in his hands.

This is almost three months ahead of the previous year's list of winners, which was not released until May or June.

Chen Zhengping smiled mysteriously and said: "Well, considering some things, this year's list of winners and award ceremonies are out earlier than in previous years, and the award ceremony has been moved from the end of July to the end of May, which can be regarded as some foreshadowing for you, and you should know after a while." ”

This aroused Xu Chuan's curiosity, but he didn't ask much, because he could almost guess.

With his current achievements, it is nothing more than the Schül-Weil Berry theorem, and there are only a few that are linked to this world-class problem.

For example, the Abel Medal and the Fields Medal two years later have not yet won a mathematics prize won by a Chinese scholar.

It's kind of setting the stage for these things.

A H.Y. Weil Berry theorem can get him 100% into the Fields Medal nomination, but whether he can win the award or not, this is not certain.

The first is that he is too young, even two years later, he is only 20 years old.

The youngest Fields Medal winner, Professor Jean-Pierre Serre, was 28 years old when he won the prize.

Not everyone is happy to reduce the age of Fields Medal winners by eight years at once, and many of the mathematicians eligible to be nominated for the Fields Medal are close to forty years old.

For example, the winner of the Morning Star Prize in Mathematics just now, Zhang Weiweishen, a tenured professor at Columbia University, who walked out of P University, is 35 years old this year.

And the mathematics conference in two years is his last hope, if he misses it, he will be 41 years old by the 2022 mathematics conference, and then the Philippine Prize will be completely insulated from him.

On the other hand, in mathematics, international mathematicians pay more attention to the ideas, results, and mathematical tools born in the process of solving conjectures or solving problems than solving conjectures.

For example, Professor Peter Schultz's 'p·s Entry Domain-Geometric Theory' tool, even if Professor Schultz has not solved a big conjecture in mathematical conjectures at present, he still firmly occupies a place in the Fields Medal two years later with this tool.

During the review of the Weyl-Berry conjecture, Professor Feverman mentioned it in his review comments, and hoped that he could sort out the ideas and methods to prove the Weyl-Berry conjecture in this regard.

In fact, this is also a subtle telling him that if he wants to win a medal at the Fields Medal in two years, the ideas and methods of solving mathematical problems are very important.

It's not that solving a mathematical conjecture isn't important, but if he can solve a T1 or true T2 math conjecture, then he will win a Fields Medal 100 percent.

But to be honest, although the Weyl-Berry conjecture is indeed more difficult, it can be close to the difficulty of the conjecture at the end of T2, but it should be classified as T3 to be precise.

In addition, the value of solving it and being born is not very large, the age and value are combined, and he has no other mathematical achievements other than the Weyl-Berry conjecture.

Therefore, it is not certain whether Xu Chuan can win the Fields Medal two years later with this conjecture.

And this time, the Morningstar Mathematics Award was determined and awarded in advance, probably to build momentum for him, hoping to make him more famous, and to drive other mathematics awards to be awarded to him within two years, so as to increase the bargaining chips.

However, Xu Chuan is noncommittal about this kind of thing.

He never thought of using the state apparatus to build momentum for himself and then to win the Fields Medal two years later.

Fame and reputation can be faked, but mathematical strength cannot be faked.

In mathematics, if you understand, you understand, if you don't, even if the Fields Medal, the Abel Medal, the Gauss Medal, the Wolf Prize in Mathematics and other top mathematics prizes are awarded to you, it is impossible for you to understand.

So compared to reputation, Xu Chuan hopes that he can understand more things.

In fact, if it was Professor Zhang Wei who solved the Weyl-Berry conjecture this time, then the Fields Medal would not have been able to run away two years later.

Because Wei Shen has made a lot of contributions to the field of mathematics, whether it is number theory or self-discipline, he has made many contributions, and he is only missing a famous big problem from the Fields Medal.

At Peking University, there is actually only one recognized Wei Shen (Wei Shen) on campus, referring to Zhang Wei, not the more famous and well-known Wei Dongyi in later generations.

The gap between the two should still be clear if you study mathematics.
