Both of them are the type of doing what they say, and after agreeing with Professor Zhou, Ye Fei settled in the computer computing laboratory.

"Professor Zhou, where are your graduate students?" The next day, Ye Fei came to the computing power laboratory and saw that there was only Professor Zhou in the entire laboratory, and no one else.

Professor Zhou said: "I am the only one in this laboratory. ”

"You're alone?" Ye Fei was stunned: "Your graduate students are not in this laboratory?" ”

"I don't have any graduate students under me."

"No graduate students?" Ye Fei was surprised, there are no graduate students under the professor?

"There was one, but it's gone."

"Applying for a transfer?" Ye Fei asked.

If you find that your supervisor is not good and you want to change your supervisor, you can choose between two options.

1. Drop out of school and retake the exam, choose a new school, and re-select a tutor.

2. Apply to the school for a change of tutor.

Both options are more difficult.

If you retake the exam, you will have to go through another postgraduate examination experience.

Anyone who has participated in the postgraduate entrance examination understands that the postgraduate entrance examination is very painful, no less than the college entrance examination.

Second, there must be a valid reason, and there must be good communication with the current tutor before you can apply to the school to change the tutor.

But it's more difficult to change tutors because there are a lot of things involved.

If the number of graduate students under the supervisor decreases, it will reduce the funding of the project under the supervisor, and there are many other problems.

Therefore, the school will not change tutors for students unless it is a last resort.

"Hmm!" Professor Zhou nodded: "Let's start!" ”

"Okay!" Although Ye Fei was very puzzled about this matter, he didn't ask much.

"We work together!" Professor Zhou said, "I study computational theory, and you study set theory. ”

The Turing equivalence problem is a problem on the boundary between the two fields of computability theory and set theory.

Computability theory belongs to the field of computer mathematics, also known as algorithm theory.

"Yes!" Ye Fei nodded.

A week later!

Ye Feidao: "Professor Zhou, my model of set theory has been done, when will you be good?" ”

"How are yours?" Professor Zhou was stunned.

"yes!" Ye Fei nodded.

"Are you sure you're right?"

Professor Zhou had to suspect that he hadn't even done half of it, but Ye Fei had done it.

Moreover, I am a professor in the School of Computer Science, not a student of those three-legged cats.

I haven't even done half of it well, Ye Fei is fine so soon?

"Why don't you take a look?" Ye Feidao.

"Okay, then I'll take a look."

He really didn't believe that Ye Fei had done a good job, he must have done it very carelessly, and if there was a mistake in it, he could blame it.

Although Professor Zhou is not proficient in set theory, he can still see whether Ye Fei deduced it carelessly.

After a long time, Professor Zhou was surprised and said to himself: "It's really not a careless deduction?" ”

"But how can it be so fast?"

He looked at Ye Fei on the side, his eyes flickering.

Ye Fei said: "Professor Zhou, is it okay?" ”

"That's it!" Professor Zhou nodded: "I still have half a month." ”

Speaking of this, Professor Zhou was a little ashamed.

I am still a computer professor, and my speed is not as fast as Ye Fei.

"I'm not in a hurry!" Ye Fei said: "You solve the computability theory first, and then we will move on to the next step." ”

Deriving computability theory and set theory is just the most basic thing about Turing equivalence.

Next, we will combine the theory of computability and set theory and apply it to the countable Borel equivalence relation.

From the countable Borel, the free group is found, the product space is deduced from the free group, the group action is found from the displacement between them, and finally the Turing relation is applied to find the equivalence relation.

This series down, every step is very difficult.

The most basic part is the simplest, Ye Fei has studied set theory for so long, and he has also proved two world problems about set theory.

Solving the most basic part of Turing equivalence is naturally very easy.

"Good!" Professor Zhou said.

Ye Fei said: "Professor Zhou, then I'll come back in half a month." ”

After speaking, Ye Fei left the laboratory and walked towards the Academic Affairs Office.

This morning, his dissertation on the problem of the smallest tower, submitted to the paper on new advances in mathematics, passed.

Now he's going to get the money.

In the end, Ye Fei persuaded his mentor through Professor Liu Yisheng to become the corresponding author, but after the paper was passed, he would not take the money and give it all to Ye Fei.

According to the convention, the corresponding author and the first author receive half of all the rewards received by the paper.

"This time it should be 400,000!" Ye Fei was excited.

The last time I submitted a manuscript to the top journal, I got 400,000 yuan, and this time it is the top journal, and it should be 400,000 yuan.

"One more top magazine, and I'll be able to buy a house in Dune City."

"If I publish six top publications, I can buy a house in a very good position."

Dune City is the capital city of Zhonghu Province, belonging to the middle and upper reaches of the Yangtze River.

In the case of high housing prices in the country, Dune City is unique, and the country is famous for its low housing prices.

When the director of academic affairs saw Ye Fei coming in, he smiled and said, "Sending papers again?" ”

Ye Fei opened the mailbox to show him.

"Top magazine again?" The dean of academic affairs looked at Ye Fei in surprise, and smiled helplessly: "Ye Fei, the new progress in mathematics will not be opened by your family!" ”

Ye Fei said with a smile: "If my family opened it, I wouldn't have come once for so long, I would come every day." ”

"When I look at our school, I count you as the most comfortable, and when you look at your papers, you not only get fame, but also money."

The dean of academic affairs said that he checked the number in the mailbox and entered the official website of New Progress in Mathematics to find Ye Fei's paper.

After he checked it, it was indeed Ye Fei's paper, and he said, "Okay, I'll let the finance send you the money tomorrow." ”

"Is it still 400,000?" Ye Fei asked.

"Of course!"

"Thanks, Director!"

Ye Fei said something and left.

The director looked at Ye Fei, who was leaving, with envy on his face.

He was really envious, he had never seen such a nourishing student alive.

It's much more comfortable than him, the dean.

"It's too easy to make money." He sighed: "This is the golden house in the book!" ”

The second morning!

The official website of Zhonghu University, Tieba, official Weibo and official Douyin will be released at the same time!

[Congratulations to the doctoral students of the School of Mathematics of our university for proving the problem of the smallest tower]

[Ye Fei, male, 22 years old, Ph.D. candidate in the School of Mathematics, mainly researching set theory

……

The paper on the minimatural tower problem was included in the top journal of Mathematics, New Advances in Mathematics.

Our school rewards 400,000!

I hope that the rest of our students will continue to work hard! 】

The students at Zhonghu University were dumbfounded when they saw the news.

"Another 400,000? I remember that last time Ye Fei was rewarded with 400,000 yuan from the school! ”

"This school has become Ye Fei's bank, and the money can be withdrawn at any time."

"Amazing, two papers have entered the top journal, and they will get 800,000!"

"Niu, I earned 800,000 yuan from school before I graduated."

“……”

On this day, I don't know how many teachers and students envy Ye Fei.

But they can only envy, they can't do Ye Fei's things.

They want to do it, but they don't have the ability to do it.

One's eyes are bigger than one's stomach.!

Everyone exclaimed: "This is the real version of the book's own golden house." ”

Nowadays, it is a common phenomenon in society that academic qualifications are not valuable.

Education is worthless, but knowledge is valuable!

Where can you get a degree without knowledge, and a degree is a certification of knowledge.

And if you have knowledge, you can be like Ye Fei, send papers, and pick up school wool.

Ye Fei thought that today's happiness would only be 400,000, but he didn't expect that there would be a surprise.

Professor Lu's office!

After Ye Fei came in, Professor Lu smiled and said, "Ye Fei, congratulations, you have been nominated for the Zhong Jiaqing Mathematics Award." ”

"Already in the nomination?" Ye Fei said in surprise: "Then the next step is to choose the winner from the nominees." ”

Zhong Jiaqing Mathematics Award from all universities or research institutes in the country, all declared scholars.

Based on their scientific research results, the best group of people will be selected for nomination.

After that, the best four nominees will be selected.

And no more than twenty people are nominated, and four people are selected by twenty, with a probability of one in five.

Therefore, if you enter the nomination, you have a high probability of winning the award.

"Yes!" Professor Lu nodded: "In a few days, we will know the list of winners." ”

Ye Fei was looking forward to it!
