Ye Fei Office!

A young man stood in front of Ye Fei.

The young man has a square face, wears black-framed glasses, has a wide body, and wears a black down jacket and dark jeans.

His name is Lin Yi, a junior at the School of Mathematics at Zhonghu University.

He spared the back of his head, a sincere smile appeared on his face, and said shyly: "Professor Ye, are you recruiting graduate students next year?" ”

After hearing that Ye Fei became an associate professor, everyone knew that Ye Fei would recruit graduate students.

Aspiring students who would have wanted to be admitted to a better university than Zhonghu University for graduate school.

But seeing Ye Fei recruiting graduate students, some students wanted to be admitted to Ye Fei's subordinates.

Many people at Zhonghu University know that Ye Fei's research speed is very fast.

Moreover, the problems he is studying now are all relatively cutting-edge problems.

If you become his graduate student, hug his thigh, and don't take off?

Therefore, there are many students who want to apply for Ye Fei's graduate school.

So, a smart person like Lin Yi has long come to spy on the military.

Ye Fei thought about it, although he said that he wanted to recruit graduate students, he had not seriously considered the requirements for graduate students.

Lin Yi saw that Ye Fei was silent, stared at Ye Fei tightly, and his heart also came up.

After a while, Ye Fei looked up at Lin Yi, who immediately retracted his gaze a little, and the whole person looked a little more relaxed.

Ye Fei asked, "You want to apply for my graduate school?" ”

"Ah......" Lin Yi said: "Yes! ”

"What's your name?"

"Lynn!"

Ye Fei said with a smile: "You study the course well, as long as the foundation is passed, I will naturally recruit, mainly in number theory, in recent years, my research direction is in number theory." ”

"When I recruit graduate students, I will mainly test number theory during the interview."

The postgraduate entrance examination is divided into a written test and an interview, the written test is the school's paper, and the interview is a face-to-face conversation between the teacher and the student.

When Lin Yi heard this, he breathed a sigh of relief in his heart and said, "What is the aspect of number theory?" ”

The scope of number theory is very wide, and if he were to learn all of them, one year would definitely not be enough.

"Gaussian functions, Diophantine diagrams, and ABC conjectures."

"No prime numbers?"

The most well-known in number theory are prime numbers, especially Mersenne primes.

Almost everyone who studies prime numbers will study Mersenne primes.

"Nope!" Ye Fei shook his head.

For prime numbers, many people may be interested in studying them, but Ye Fei is not interested in them.

This is a sinkhole, such a pit, Ye Fei is not interested in entering.

"Thank you, Mr. Ye!" Lin Yidao.

With that, he turned and left.

Zhong Wei said: "Ye Fei, you said that you have been studying number theory in recent years? ”

"Hmm!" Ye Fei said: "Yes, I have been studying number theory in the past few years. ”

"Don't study anything else?" Zhong Wei asked, "For example, algebra, geometry, partial differentiation, nonlinearity?" ”

"Others will definitely go to research." Ye Fei said: "But number theory is a big study after all, and many mathematicians can't finish their research in a lifetime, so I can't be greedy, so I will focus on number theory research for the time being." ”

"Unless there is no progress in number theory research, we will study anything else."

"As for what aspects of research, we mainly see where the research is trapped, and then find breakthroughs in other fields according to the trapped aspects."

Ye Fei's method is also a method studied by many mathematicians.

There is an interdisciplinary study between the various fields of mathematics, such as number theory geometry, algebraic geometry, number theory partial differential, and algebraic partial differential.

If one area is struggling, it can be helpful to study other areas related to the struggling domain.

This is called academic linkage.

"You're done with your ABC conjecture." Zhong Wei said: "What are you studying now?" ”

"Gaussian conjecture?"

Tan Lingling said: "Gauss conjecture? Haven't you proven it out? ”

The other three in the office stared at her in silence.

"What's wrong?" Tan Lingling's face was confused.

Ye Fei said amusedly: "When did I prove the Gaussian conjecture?" You're talking about a Gaussian circle, that's a Gaussian circle, not a Gaussian conjecture. ”

"The names are different, they are different."

Tan Lingling blushed instantly, knowing that she had made a big mess.

The other two shook their heads in their hearts, but they weren't surprised.

After all, is it Tan Lingling, a Tan Lingling who has no ambition at work and has not achieved much in academics.

Zhong Wei said: "You have proved the ABC conjecture, don't you think it is difficult to prove the Gauss conjecture again?" ”

In terms of difficulty, the ABC conjecture is much more difficult than the Gaussian conjecture.

Mathematicians love challenges, and when they have proved a difficult problem, they rarely prove a difficult one.

It's like a person who has eaten abalone and rarely eats sea cucumber again.

Ye Fei said: "No, the reason why I was able to prove the ABC conjecture is that there are many previous experiences, and there are many people around the world who have proved the ABC conjecture, and I have learned from their theories and found new ideas after summarizing." ”

"Actually, in terms of difficulty, I think the Gauss conjecture is more difficult than the ABC conjecture."

"Also, you may have a misconception that the ABC conjecture is more difficult than the Gauss conjecture, but in fact, the Gaussian conjecture is not simpler than the ABC conjecture at all.

This man was Nice Alain Baker, who proved the number of classes of quadratic fields for some problems in number theory, and became the winner of the Fields Medal in 1970.

Han Dong shook his head in his heart, this Zhong Wei is still studying mathematics, why doesn't he even know this basic knowledge?

Han Dongdao: "Ye Fei is right, Gauss's conjecture is not as simple as you think, and many of the problems in it may win international awards." ”

Zhong Wei asked: "Ye Fei, you said that if you prove the Gaussian conjecture, what international awards can you win?" ”

Ye Fei shook his head and said: "It's almost impossible to win a big award, but a small international award can be won." ”

"Huh?" Tan Lingling asked, "Why is that?" Didn't you say that the Gauss conjecture is no less difficult than the ABC conjecture? ”

Ye Feidao: "Difficulty is difficulty, but winning awards is not based on difficulty, but on effect." ”

"The role of Gauss's conjecture is to generalize the number theory of rational numbers to the number theory of algebraic numbers."

"In terms of function, it is much weaker than the ABC conjecture."

"So, even if I prove the Gauss conjecture, I won't be able to win a major international award."

"Unless you can prove a math problem that has a huge effect."

"Didn't you say that someone who proved the problem from the Gauss conjecture won the Fields Medal?" Tan Lingling was completely confused.

Ye Feidao: "This is a very complicated problem, and the reason why Baker can win the Fields Medal is because he extracted a small problem from the Gaussian conjecture and derived it, and finally proved a problem with great effect. ”

"It's like a tree, someone takes a part of the tree, makes a wood carving, and ends up selling it for a very high price."

"So, do you understand?"

Tan Lingling nodded and said: "So that's the case, then why do you bother to prove the Gauss conjecture, it's better to take a part of the Gauss conjecture and study it, even if you can't win the Fields Medal, you can get a big international award!" ”

When Ye Fei heard this, he was speechless in his heart, and said, "Eldest sister, we also have that ability, do you think that the big international award is so easy to get?" ”

Ye Fei's academic accumulation is not enough, maybe after a few years, he can try.

At this time, Ye Fei's phone rang.

"Huh?" Ye Fei took out the phone and wondered: "Why did Professor Qu call me?" ”

Professor Qu is Professor Guangjie Qu, Professor of Mathematics at Fudan University.

They haven't been in touch for a long time.

Ye Fei answered the phone and said with a smile: "Professor Qu, hello!" ”

"Haha......" Professor Qu laughed and said, "Ye Fei, you are famous at home and abroad now!" ”

"Nothing." Ye Fei smiled and said, "Professor Qu, do you have anything to do with me?" ”

"That's right, Ye Fei, our school wants to invite you to be a visiting professor at our school, what do you think?"

"Visiting professor?" Ye Fei was stunned for a moment.

Each school has different requirements for visiting professors, and the better the school, the higher the requirements for visiting professors.

Fudan University, as one of the top universities in Xia and one of the top five universities in the country, has very high requirements for visiting professors.

Of course, the visiting professors of Fudan University are very demanding and have a high gold content.

Visiting professors at Fudan University must first be associate professors and be no more than 60 years old.

In addition, the majors and research directions engaged in are in line with the development needs of Fudan University, and they can come to Fudan University every year to conduct cooperative research and give several academic lectures.

Ye Fei said hesitantly: "Professor Qu, I have no research cooperation with Fudan!" ”

It's okay to be a visiting professor, but at least he needs to cooperate with Fudan University.

However, his current research does not require the cooperation of Fudan.

"It doesn't matter, as long as you can come to Fudan once or twice a year for academic lectures," Professor Qu said. ”

Visiting professors are honors to professors themselves, and well-known professors joining Fudan University as visiting professors at Fudan University are also honors to Fudan University.

Ye Fei has now proved the ABC conjecture and is a well-known mathematician at home and abroad, so it is an honor for Fudan University that he has become a visiting professor at Fudan University.

Ye Fei thought for a while and said, "Yes, but this requires Fudan University and Zhonghu University to talk." ”

"Okay, I'll go back and let the school talk to Zhonghu University."

Since Ye Feidu agreed, then Zhonghu University should also be able to agree.

After all, he is just a visiting professor, and he is not poaching Ye Fei to Fudan to become a lecturer.
