From university academician to chief academician

A week later!

Song Chengkun completed the school's job retention procedures, carried large and small bags, and got on the plane to Zhonghu.

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

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

Song Chengkun stepped forward and said with a smile: "Professor Ye, I'm sorry to ask you to pick me up. Actually, there's no need. I can find a place by myself and I can go there myself."

With that said, he handed the luggage to Ye Fei unceremoniously.

Ye Fei took his luggage with a smile and said, "I should come to pick you up. How can I let you go there in person? If you get lost, I will have to go to the police station to find you. That will be a lot of trouble!"

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

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

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

This car was bought by Ye Fei, who was worth over 100 million anyway.

Buying a Mercedes-Benz E is nothing.

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

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

Either he is very capable, and in addition to the school salary, there are many opportunities to make extra money, such as Ye Fei.

Ye Fei is not an exception in school. Anyone with a little bit of ability has the opportunity to make extra money.

University teachers never live on school salary, but on earning extra money.

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

Of course, without the platform of a university, there would be far fewer opportunities to make extra money.

Precisely because of the platform of university, there are many more opportunities to make extra money.

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

While driving, Ye Fei said, "I'm here to find you, in addition to studying the distribution of prime numbers together."

Before Ye Fei could finish speaking, Song Chengkun shook his head repeatedly and said, "No, no, no, I'm just here to take a look, not to study together."

Ye Fei didn't care whether he was studying together or not. You and everyone are here, and you still said they weren't studying together. You're such a tough talker.

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

"You need my help?" Song Chengkun smiled.

"Yeah!" Ye Fei nodded.

"Easy to say, easy to say." Song Chengkun smiled and said: "I'll help you take a look!"

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

But Ye Fei also has areas where he is weaker than himself in the field of prime numbers.

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

Ye Fei smiled and said: "This is not just a look. You have to resolve my matter, and we have to sign a confidentiality agreement. You know these rules, right?"

"Of course!" Song Chengkun said.

It is industry standard to sign a confidentiality agreement before joining a study.

Otherwise, if you leave the research room, the research information can be leaked out at will.

Ye Feidao: "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, four months later. The quotation I will give you is one million, what do you think? "

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

For a person like him to go out and give a speech, the price is 40,000 to 50,000.

To do research, you will be charged by the hour or by the time you pay.

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

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

Ye Feidao: "Can I still lie to you?"

"I remember it was less than half a year since you started researching asymmetric encryption algorithms!"

"Yes!" Ye Fei nodded: "I started researching it after attending the Ho Leung Ho Lee Award Ceremony last time."

Song Chengkun stared at Ye Fei blankly, feeling suddenly heartbroken.

Damn, what have you been going through for the past three months?

While there are infinite twin primes, this problem is proved.

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

Moreover, the research speed is so fast.

For a long time, Song Chengkun said depressedly: "You have already studied it, why are you coming to me?"

Ye Feidao: "This speed is based on your participation. It will be completed in four months."

"Haha..." Song Chengkun laughed and said, "So that's it. I will help you well and try to help you complete your research as soon as possible."

Song Chengkun regained his confidence again. It turned out that it was only with his own help that he was able to complete the project four months later.

So my research on Ye Fei is very important.

Therefore, Ye Fei cannot do without himself.

Song Chengkun asked with a smile: "How long will it take to complete it without my help?"

Ye Feidao: "It will be delayed by two months!"

The corners of Song Chengkun's mouth stiffened for a moment, and then he looked at Ye Fei dumbfounded. The expression on his face gradually changed from dull to painful: "Only a two-month delay?"

Ye Fei drove carefully while looking ahead, and did not notice Song Chengkun's expression. Ye Fei nodded and said, "Yes."

Song Chengkun really wanted to slap himself at this moment.

You big loser!

With you, I am two months ahead of schedule; without you, I am just two months behind.

Is two months considered time for a study?

So, it’s the same with or without you.

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

Ye Feidao: "Yes, but with you here, can't we advance it by 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 can be completed 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.

"Yes!" Ye Feidao: "That's 26 days."

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

Song Chengkun spent more than three months studying the infinite number of twin primes, and only found the beginning of the proof.

It took Ye Fei 26 days to succeed.

Song Chengkun helped Ye Fei do research and could complete it two months in advance.

Without Song Chengkun's help in research, completion was delayed by two months.

Song Chengkun: "..."

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

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

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

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

Bay University is equivalent to a C9 prestigious university in mainland China. Those who work as third-level mathematics professors at Bay University are all people with superior IQs.

Such a person is one in a million.

"How about comparing with 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 and gave up.

A person who has studied prime numbers for nearly twenty years is worse than a person who has not studied prime numbers much.

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

After parking the car, Ye Fei said: "I will take you to meet the people in my research room first, and then I will arrange your accommodation."

"Okay!" Song Chengkun smiled and nodded.

For nearly an hour, Song Chengkun adjusted his mentality.

Since he is not as good as Ye Fei, then there is no comparison.

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

When everyone looked in their direction, Ye Fei said: "Everyone, let me introduce to you. This is Professor Song Chengkun from Bay University."

"Professor Song Chengkun is a famous mathematics professor at Bayan University. He mainly studies prime numbers. He has been studying prime numbers for nearly 20 years."

"I invited him here, which was very helpful to our research."

"Everyone is welcome!"

"Bah bang bang..." Everyone applauded enthusiastically, and some people even knew Song Chengkun.

Song Chengkun is relatively famous in the prime number circle.

In terms of prime number ability, he is among the best in Xia Kingdom.

Of course, in terms of research ability, it is incomparable to Ye Fei, the wall-hanger.

Song Chengkun put a smile on his face at the right time and said: "I am very happy to meet you all. I hope we can work happily in the days to come. I will also do my best to work with you and complete the research as soon as possible."

There were 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 accommodation for Song Chengkun.

At Zhonghu University, the most indispensable thing is accommodation. Ye Fei arranged for him to stay in the classroom apartment, which is where Ye Fei lives.

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

The next day, Blockchain Research Laboratory, Ye Fei’s office!

Ye Fei and Song Chengkun were sitting in the office. Ye Fei said, "Let me first tell you about our recent research in the laboratory."

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

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

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

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

"What's wrong?" Ye Fei asked.

"That's really awesome!" Song Chengkun gave a thumbs up and said: "Most 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 is one of the seven major problems in mathematics. Deducing the 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 and I don't do it, the problem will never be solved."

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

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

"Do your best to obey fate."

"If it doesn't work out, you can't blame me."

Ye Fei smiled and said: "I won't blame you if it doesn't work out. This can only mean that our abilities are not enough."

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

Ye Feidao: "Now!"

"Can!"

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

"good!"

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

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

ζ(s)=∞∑n=1(n^-s)

Here, Riemann began to use complex variable function theory to study number theory problems, 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 the set of natural numbers, mathematicians are also interested in the distribution of prime numbers on some special sequences.

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

Time passed unknowingly 62 years ago and arrived in 2015.

Over the past 62 years, mathematicians have continued to study the distribution of prime numbers and continued to advance their research toward formulas representing 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 prime numbers on a jumping sequence.

In 2017, Kellner proved that the proofs of Podel, Luca, Morey and Shpalinski were true through Bernoulli polynomials.

And the constant k=2.

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

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

Only with elementary proof can the following proof be carried out.

Song Chengkun said: "According to my many 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 represents the function and is an important research object in combinatorial number theory. The research on the representation function should be like this."

Song Chengkun said as he picked up the pen on the table and wrote a long article on the paper.

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

After reading what Song Chengkun wrote, Ye Fei frowned and thought, "Is your proof too complicated?"

"Huh?" Song Chengkun was stunned 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!"

Ye Fei said, writing some formulas on the paper.

"If it is deduced this way, will it be more concise?"

Song Chengkun nodded after reading it and was surprised: "It's really more concise."

"This..." Song Chengkun looked up at Ye Fei and asked, "Don't you have no deep research on prime numbers?"

"Yes!" Ye Feidao: "I simplified it based on your deduction!"

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

Song Chengkun thought to himself: "How does Ye Fei's brain grow? Can you deduce this?"

Ye Feidao: "Let's continue!"

Half a month later!

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

"With this proof, we can successfully derive the elementary proof."

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 encryption algorithms."

Song Chengkun asked tentatively: "Ye Fei, how about we continue studying prime numbers?"

Ye Fei shook his head and said: "This has been researched, what else are you studying!"

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

At this moment, Song Chengkun tasted the sweetness. He found that studying with Ye Fei was so delicious.

Ye Fei's brain is so good that he only needs to ask many questions and find solutions to them.

Ye Fei quickly solved the problem and made it simpler than his own proof.

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

Thinking of this, Song Chengkun felt hot in his heart.

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

Song Chengkun said anxiously: "Why is it not necessary? I think it is very necessary. You see, you have the brains and I have the ideas. Together, we can prove more prime number problems."

Ye Fei looked at Song Chengkun suspiciously.

"What's wrong?" Song Chengkun felt uncomfortable looking at Ye Fei.

Ye Feidao: "I don't think your ideas are very reliable. I have simplified many of your ideas in the past half month."

"You..." Song Chengkun looked aggrieved.

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

Ye Fei didn't want to study too deeply in the field of prime numbers, otherwise he would be trapped in it and he might not be able to get out.

"Hey..." Song Chengkun sighed helplessly when he saw that Ye Fei had made up his mind.

"If heaven had not given birth to me, Song Chengkun, I would have been like a long night forever!"
