From all-round academic master to chief scientist

School of Mathematical Sciences, Shanghai University.

Professor Xu Ji's office.

"Professor, look at my question here. Is this residual class mapping a homomorphism from ring Z to ring Z/nZ?"

Xiao Zhou asked Professor Xu for advice on the problems he encountered.

But before Xu Ji could answer, there was a knock on the door and Da Zhou came.

Zhou Wu opened the door and came in. He smiled and said to Professor Xu Ji: "Professor Xu, have you read the latest issue of "Annals of Mathematics"?"

Xu Ji gestured to Xiao Zhou and asked him to ask again later, then responded with a smile and pointed at the article being displayed on the computer screen.

"Haha, I'm watching right now."

There was no doubt that he was reading Lin Xiao's paper.

He sighed: "It was actually arranged to be published in this issue. It was very early, and it was the first article. But having said that, this student is really amazing. People in the editorial department of the Annual Journal of Mathematics still know about this paper. The importance of it.”

Lin Xiao's paper was published in the journal within just a few months after passing the review, and was placed in the first article position, which is enough to show that the value of this article is considered to be very outstanding.

At this time, Xiao Zhou next to him walked aside, made way for Zhou Wu, and brought him a chair. Then he couldn't help but look at Xu Ji's computer screen, feeling emotional in his heart.

This is the "Annals of Mathematics". If he can publish a paper in it, it will be worth his life.

Zhou Wu thanked him, sat on the chair, and said with a smile: "They must understand the importance of this paper. This is good news for researchers in the field of prime numbers, as well as the challenges faced here." The analysis of nonlinear problems of polynomial functions is an absolute stroke of genius.”

"And the reviewer is Peter Sarnak, the previous winner of the Wolf Prize in Mathematics. He also left a comment, which was also very good."

"Oh? Let me take a look."

When Xu Ji heard that a winner of the Wolf Prize in Mathematics had left a good comment, he immediately slid the mouse wheel and turned to the last page.

Soon, he turned to the bottom and saw the comment left by Professor Sarnak.

"This paper uses a groundbreaking innovative method to open the door to the prime number problem. So, let us solemnly introduce a seventeen-year-old mathematical genius to the world! 』

"Breaking innovation, this evaluation is indeed very high."

Seeing this comment, Xu Ji couldn't help but say.

In the comments of the paper, there are some more important words that are rarely used, such as 'breakthrough innovation', which means that the knowledge used in this paper is a method that no one in the entire academic world has tried. .

Obviously, Lin Xiao's paper has been greatly recognized by the winner of the Wolf Prize in Mathematics.

The Wolf Prize in Mathematics is also a very valuable award in the field of mathematics. Together with the Fields Medal, it is regarded as the highest honor in the field of mathematics.

After all, the Fields Medal can only be awarded to mathematicians under the age of 40, and mathematicians over the age of 40 have no chance, so the Wolf Prize in Mathematics, which has no age limit, will undoubtedly become their pursuit. goal, so the Wolf Prize in Mathematics is also quite popular.

Among Chinese mathematicians, just like the Fields Medal, the number of Chinese mathematicians who have won the Wolf Prize in Mathematics with their own nationality is still zero.

Therefore, for professors like Xu Ji and others, mathematicians who have won this award can give such a high evaluation, especially since Professor Sanak also specifically stated Lin Xiao’s age and called him a mathematical genius. It is enough to prove that Lin Xiao has been recognized in the world.

"What a terrifying life."

Xu Ji sighed with emotion again.

"I'll have to meet him in person when he comes to class in September."

"Actually, you can see him in the next few days." Zhou Wu said with a smile.

"Huh?" Xu Ji was stunned: "Why?"

"Because he entered the IMO national team, he has come to Beijing to participate in training, and now he is at the Academy of Mathematics of the Chinese Academy of Sciences."

Xu Ji stood up immediately: "Let's go and meet him now! This kind of student must establish a good relationship in advance, otherwise other old guys in the college may have to compete with me."

"That's true." Zhou Wu couldn't help but laugh, and at the same time he couldn't help but feel envious. Only these big guys could snatch such good students. He, a little associate professor, would only be able to teach Lin Xiao one lesson. Taught him.

Maybe it will still be a question whether Lin Xiao will go to class.

"Are you going?" Xu Ji asked as he packed his things.

"I... let's go together. It just so happens that I don't have class today either."

"Um."

Xu Ji said no more. After quickly picking up the things, he said to Xiao Zhou next to him: "Ask your question to Professor Yu next door. If you really don't understand, just wait until I come back."

Xiao Zhou had no choice but to nod. The professor was going to meet another big boss. A graduate student like him at Beijing University might be a very impressive figure in front of ordinary people, but he had stayed at Beijing University for a long time. Only then did he realize that there were more bosses in the world who were more awesome than him.

The guy who has not even graduated from high school, and who can publish the "Annual Review of Mathematics" even at the age of seventeen, obviously belongs to this kind of big boss.

…

at the same time.

Chinese Academy of Sciences, Academy of Mathematics.

At this time, Lin Xiao was not studying, but listening to a report.

The speaker is Sun Xiong, a researcher at the Academy of Mathematical Sciences.

As for the levels of researchers at the Chinese Academy of Sciences, the 'researcher' level is the highest, that is, the senior level, which is the same level as professors in universities.

Therefore, to be able to hold a senior professional title in the Academy of Mathematics of the Chinese Academy of Sciences, this speaker's status is naturally quite high.

As for the theme of this report, it is the recent research results of researcher Sun Xiong, about the problems in the representation theory of typical groups.

"Over the years, my collaborators and I have achieved outstanding results on the Langlands Program, which I can proudly say, verbatim - we have solved the problem of typical group multiplicities. First conjecture, as well as the three most basic issues in the typical group Theta correspondence theory: the multiplicity conservative conjecture, the conservation law conjecture and the duality conjecture. These results laid the foundation for the related L function theory, and last year, I also completed the proof The L-function non-null hypothesis proposed by famous scholars in the 1970s."

"Today, what I want to share with you is another major breakthrough in our typical group representation theory."

"As we all know, Lie groups are mathematical characterizations of space symmetry. Typical Lie groups are some Lie groups that appear widely in mathematics and physics, including general linear groups, orthogonal groups, symplectic groups, unitary groups, etc., so next I will An introduction to typical Lie groups and their finite- and infinite-dimensional representation theory.”

"Now, please turn to the first page of the paper."

…

In the seat below, Lin Xiao opened the paper handed out before the report and came to the first page.

Since he had already finished all the undergraduate knowledge, he had already started studying at the postgraduate level. Based on the selection, he chose Lie groups in group theory.

As for why?

He chose it simply because the name sounded like a personal name and intrigued him.

After studying for more than half a month, he heard that there was a report on the representation theory of Lie groups, so he came here with the intention of listening to it.

However, after listening for a while, he suddenly received a prompt from the system.
