From a university student to a chief academician

Chapter 154 Song Chengkun was not born to me, the prime number is like a long night!
A week later!

Song Chengkun went through the school's job retention procedures, carried the big bags and small bags, and boarded the plane to Zhonghu.

A few hours later, Song Chengkun came out of the airport with his luggage.

Ye Fei waved his hand outside the pick-up hall and said, "This is it!"

Song Chengkun stepped forward and said with a smile: "Professor Ye, I'm really sorry to ask you to pick me up. Actually, I don't need it. I can find a place to go by myself, and I can go by myself."

With that said, he unceremoniously handed over the luggage in his hand to Ye Fei.

Ye Fei took his luggage with a smile, and said: "I should come to pick you up, I can't let you go there in person, if I get lost, I have to go to the police station to find you, what a bother!"

"You think I'm a three-year-old kid, and I still go to the police station, don't I know how to search on a map?" Song Chengkun glanced at Ye Fei, speechless.

Ye Fei smiled and said, "Get in the car!"

After speaking, Ye Fei took Song Chengkun's luggage and walked to the parking lot, and finally got into a black Mercedes-Benz E.

This car was bought by Ye Fei, who is worth over [-] million anyway.

Buying a Mercedes-Benz E is nothing.

Among the luxury cars owned by many teachers in the school, Ye Fei's car is relatively low-key.

Most of the university teachers are rich, or from a good family background, such as Tan Lingling.

Either they have strong ability, besides the school salary, there are many opportunities to earn extra money, such as Ye Fei.

Ye Fei is not an exception in school, as long as he has a little ability, everyone has the opportunity to earn extra money.

University teachers never live off their school salaries, but on side money they earn.

The school salary is only the basic salary, which accounts for a very small part of the annual income, and most of the income comes from extra money.

Of course, without the platform of a university, the chances of earning extra money are much less.

Because of the university platform, there are many more opportunities to earn extra money.

After getting in the car, Ye Fei drove straight to the Blockchain Research Office of Zhonghu University.

While driving, Ye Fei said: "I came to you, except to study the distribution of prime numbers together."

Before Ye Fei could finish speaking, Song Chengkun shook his head again and again and said, "No, no, I'm just here to take a look, it doesn't count as studying together."

Ye Fei didn't care whether he was studying together or not, you all came, and you said not to study together, the dead duck is stubborn.

Ye Fei continued: "And my research needs the help of someone like you who has studied prime numbers for many years."

"You need my help?" Song Chengkun smiled.

"En!" Ye Fei nodded.

"It's easy to say, easy to say." Song Chengkun said with a smile: "Let me help you take a look!"

Song Chengkun has regained his confidence. Although Ye Fei proved the infinite number of twin prime numbers, this problem.

But Ye Fei is also weaker than himself in the field of prime numbers.

No, Ye Fei wants to help him in the field of prime numbers now.

Ye Fei smiled and said: "This is not to see, you have to settle my matter, and we have to sign a non-disclosure agreement, you understand these rules!"

"Of course!" Song Chengkun said.

It is an industry norm to sign a non-disclosure agreement before joining a study.

Otherwise, they may walk out of the research room, and the research information can be leaked out at will.

Ye Fei said: "Of course, I have to follow the rules. Let's talk about the price. The research can be completed in December this year, that is, after four months, I will give you a quotation of 100 million. What do you think?"

This is the extra money of university teachers. Song Chengkun is a third-level professor at the University of Wanwan.

For a person like him, going out to give a speech costs [-] to [-].

To do research, you are charged by the hour or by the session.

The research on the asymmetric encryption algorithm ended after four months, and Ye Fei felt that it would be cheaper to charge on time.

"It will end in four months?" Song Chengkun looked at Ye Fei in surprise: "Are you sure?"

Ye Fei said: "Can I still lie to you?"

"I remember you started working on asymmetric encryption algorithms less than half a year ago!"

"Yeah!" Ye Fei nodded, "I started researching after attending the Ho Leung Ho Lee Award Ceremony last time."

Song Chengkun stared blankly at Ye Fei, suddenly feeling very prickly.

Nima, what have you experienced in the past three months.

At the same time, the twin primes are infinite, and this problem is proved.

On the other side, you are not idle, studying asymmetric encryption algorithms.

Moreover, the research speed is still so fast.

After a long time, Song Chengkun said depressedly: "You have already researched it, why are you looking for me?"

Ye Feidao: "This speed is completed in four months with you joining."

"Haha..." Song Chengkun laughed and said, "It turns out that's the case. I will definitely help you and try to let you complete the research as soon as possible."

Song Chengkun regained his confidence. It turned out that it was only with his own help that he could finish it in four months.

Then I said that my research on Ye Fei is very important.

Therefore, Ye Fei can't do without himself.

Song Chengkun asked with a smile: "Without my help, how long would it take to finish?"

Ye Fei said: "It will be delayed for two months!"

The corners of Song Chengkun's mouth froze instantly, and then he looked at Ye Fei dumbfounded, the expression on his face gradually changed from sluggish to painful: "Only delayed for two months?"

Ye Fei was driving hard while looking ahead, but didn't notice Song Chengkun's expression. Ye Fei nodded and said, "Yes."

Song Chengkun really wanted to slap himself at this moment.

You big trash!
With you two months ahead, without you just delayed two months.

Is two months considered time for a study?
So, it's the same with you or without you.

Song Chengkun said depressedly: "It's only delayed for two months, and you still come to me, can't you complete the research by yourself!"

Ye Fei said: "It is possible, but with you, can we advance two months!"

"It's only two months, does this count as time?"

Ye Fei nodded and said: "Why doesn't it count as time, of course it counts as time, two months, I can do a lot of things, a simple math problem, I can basically complete it in one month, two months can be completed in two months. "

"For example, it took me 26 days to complete the infinite problems of twin prime numbers."

"What? 26 days?" Song Chengkun exclaimed.

"That's right!" Ye Fei said, "It's 26 days."

Song Chengkun's self-confidence was shattered at this moment.

Song Chengkun spent more than three months researching the infinite number of twin primes, and only found signs of proving the idea.

Ye Fei succeeded in 26 days.

Song Chengkun helped Ye Fei do the research, which could be completed two months ahead of schedule.

Without Song Chengkun's help to do the research, the completion was delayed by two months.

Song Chengkun: "..."

Ye Fei suddenly felt that the whole world was quiet. Song Chengkun, who was talking just now, seemed to be silent now.

Ye Fei turned his head to look at Song Chengkun, and asked suspiciously, "What's wrong with you?"

"It's okay!" Song Chengkun shook his head: "I just feel like a waste."

"Don't say that about yourself." Ye Fei said with a smile: "If you are trash, most people in the world are trash."

The University of Bay Province is equivalent to a famous C9 school in mainland China, and those who work as third-level mathematics professors in the University of Bay Province are all people with superior IQs.

Such a person is one in a million.

"How about compared to you?" Song Chengkun stared at Ye Fei.

"Uh..." Ye Fei hesitated and said, "You can't compare with me."

Song Chengkun covered his face sadly, dying.

A person who has studied prime numbers for nearly 20 years is not as good as a person who has not studied prime numbers much.

After nearly an hour's drive, the car entered the building of the Blockchain Research Office of Zhonghu University.

After parking the car, Ye Fei said, "I'll take you to meet the people in my laboratory first, and then arrange your accommodation."

"Okay!" Song Chengkun nodded with a smile.

After nearly an hour, Song Chengkun adjusted his mind.

Since it's not as good as Ye Fei, then it's no match.

After the two entered the research room, many researchers were doing research, and Ye Fei clapped his hands to attract everyone's attention.

When everyone turned to look at them, Ye Fei said: "Everyone, let me introduce you, this is Professor Song Chengkun from Wanzhou University."

"Professor Song Chengkun is a well-known professor of mathematics at the University of Guangdong Province. He mainly studies prime numbers. He has studied prime numbers for nearly 20 years."

"I invited him here, which is very helpful for our research."

"Everyone is welcome!"

"Papa..." Everyone applauded enthusiastically, and some of them even knew Song Chengkun.

Song Chengkun is relatively well-known in the circle of prime numbers.

In terms of prime number ability, he is top-notch in Xia Kingdom.

Of course, in terms of research ability, it is incomparable with Ye Fei, who is hanging on the wall.

Song Chengkun showed a smile on his face at the right time, and said: "It's a pleasure to meet you all. I hope that we can work happily in the days to come. I will do my best to work with you and complete the research as soon as possible."

There are four research rooms in total, and Ye Fei took Song Chengkun to the other three research rooms.

After getting to know all his colleagues, Ye Fei arranged for Song Chengkun to live.

At Zhonghu University, the most important thing is housing. Ye Fei arranged him in the classroom apartment, which is where Ye Fei lives.

Ye Fei never bought a house. He thought he might move out in the future, so he didn't buy a house.

The next day, Ye Fei's office in the blockchain research room!
Ye Fei and Song Chengkun were sitting in the office, Ye Fei said: "Let me tell you about our recent research in the laboratory."

Next, Ye Fei told Song Chengkun about the research in the laboratory in detail.

After a long time, Ye Fei said: "The research is generally like this."

"The problem now is to derive an elementary proof of the distribution of prime numbers to help the research of encryption algorithms."

Song Chengkun said in surprise: "You actually want to deduce an asymmetric encryption algorithm from Goldbach's conjecture, this idea..."

"What's wrong?" Ye Fei asked.

"It's real!" Song Chengkun said with a thumbs up: "Ordinary people don't dare to have this idea, even if they have this idea, they don't dare to try it, even if they try, they will definitely fail."

"Goldbach's conjecture, that is one of the seven major problems in mathematics. Deriving an asymmetric encryption algorithm from Goldbach's conjecture is no less difficult than proving the ABC conjecture!"

Ye Fei nodded and said: "The difficulty is quite high, but if you don't do it, I don't do it, the problem will never be solved."

"So, we should be the first to eat crabs."

Song Chengkun said helplessly: "To be honest, I admire your courage, but I can only do my best to help you. I can't guarantee success."

"Do your best to obey the destiny."

"If you don't succeed, you can't blame me."

Ye Fei smiled and said, "I'm sure I won't blame you if it doesn't work. It can only mean that we are not capable enough."

Song Chengkun nodded and said, "When will we start?"

Ye Fei said: "Now!"

"can!"

Ye Feidao: "Let's first study the previous research on the distribution of prime numbers."

"it is good!"

The distribution of prime numbers was discovered in 300 BC and proposed in 1859.

In 1859, Riemann introduced an important function by treating s in Euler's identity as a complex variable.

ζ(s)=∞∑n=1(n^-s)
Here, Riemann began to use the theory of complex variable functions to study number theory issues, which pointed out the direction for future research on π(x).

In 1986, Hadamard and Poussin independently proved the prime number theorem.

In addition to the distribution of prime numbers on natural number sets, mathematicians are also interested in the distribution of prime numbers on some special sequence.

In 1953, Piatecki Shapiro studied the distribution of prime numbers on the number sequence, made some proofs, and gave a more concise proof of the distribution of prime numbers.

62 years have passed unknowingly, and it is 2015.

For 62 years, mathematicians have continued to study the distribution of prime numbers, and have continued to advance the research to the expression formula of the distribution of prime numbers.

Of course, there is still a long way to go before success.

In 2015, Guo studied the distribution of Piatsky-Shapiro-type primes on the jump sequence.

In 2017, Kellner proved that the proofs of Bodel, Luca, Morey and Shparinsky were established through Bernoulli polynomials.

And the constant k=2.

What Ye Fei wants to study now is whether he can deduce the elementary proof of the distribution of prime numbers.

The so-called elementary proof is one of the studies on the distribution of prime numbers, and it is the key to unlock the final proof of the distribution of prime numbers.

The following proofs can be done only with elementary proofs.

Song Chengkun said: "According to my years of research on prime numbers, if you want to prove the elementary proof of the distribution of prime numbers, you should look for it from the Abelian group."

"The Abelian group is an important research object in combinatorial number theory, and the research on representation functions should be like this."

Song Chengkun said, picked up the pen on the table, and wrote a long speech on the paper.

After finishing writing, Song Chengkun looked at Ye Fei, ready to accept his praise.

After reading what Song Chengkun had written, Ye Fei frowned and thought, "Isn't your proof too complicated?"

"Huh?" Song Chengkun was taken aback for a moment.

Ye Feidao: "If h is a given integer not less than 2, G is a finite Abelian group, and A is a non-empty subset of G."

"Look!"

As Ye Fei spoke, he wrote down some formulas on the paper.

"Isn't it more concise if you deduce it this way?"

Song Chengkun nodded after reading it, surprised in his heart: "It's really more concise."

"This..." Song Chengkun looked up at Ye Fei and asked, "Don't you have a deep research on prime numbers?"

"Yes!" Ye Fei said, "I simplified it based on your derivation!"

"Can it still be like this?" Song Chengkun looked at Ye Fei dumbfounded.

Song Chengkun thought to himself: "How did Ye Fei's brain grow, can this be deduced?"

Ye Fei said: "Let's continue!"

After half a month!

Ye Feidao: "So, let x be the characteristic function of set A..."

"With this proof, the elementary proof can be deduced smoothly."

Song Chengkun nodded and said, "Yes!"

"Okay!" Ye Fei put down his pen and said: "The elementary proof of the distribution of prime numbers has been proved, so we can continue to study the encryption algorithm."

Song Chengkun asked tentatively, "Ye Fei, why don't we continue to study prime numbers?"

Ye Fei shook his head and said, "I've researched all of this, so what else is there to study!"

"No!" Song Chengkun said: "There are still many fields of prime numbers that can be studied. You see, if the two of us cooperate, we can study more difficult problems of prime numbers."

At this moment, Song Chengkun tasted the sweetness, he found that studying with Ye Fei was too sweet.

Ye Fei's mind is so good that he only needs to ask many questions and find the way to solve them.

Ye Fei quickly solved the problem, and it was more simplified than his own proof.

Song Chengkun thought: "With Ye Fei's ability, if I cooperate with him, apart from the seven major mathematics problems, other prime number problems can be proved."

Thinking of this, Song Chengkun's heart became hot.

Ye Fei shook his head and said, "No need, the current research is enough."

Song Chengkun said anxiously: "Why is it unnecessary? I think it is very necessary. You see, you have brains, and I have ideas. Our two swords can prove more prime number problems."

Ye Fei looked at Song Chengkun suspiciously.

"What's wrong?" Song Chengkun felt uncomfortable being watched by Ye Fei.

Ye Fei said: "I don't think your thinking is very reliable. In the past half month, many of your thinking have been simplified by me."

"You..." Song Chengkun was aggrieved.

"Stop talking nonsense." Ye Fei said: "Now that the prime number distribution is solved, let's start the research on asymmetric encryption!"

Ye Fei doesn't want to do too much research in the field of prime numbers, otherwise he might not be able to get out if he gets stuck in it.

"Hey..." Seeing that Ye Fei had made up his mind, Song Chengkun sighed helplessly.

"Heaven did not give birth to me, Song Chengkun, the prime number is like a long night!"
