From university academician to chief academician

Ye Fei has moved to a single apartment in the teachers' community next to the school.

After returning to my residence, I started packing my luggage and flew home that day.

Less than a week after returning home, Academician Liu contacted him again.

"Ye Fei, do you know the 608 Institute in Zhonghu Zhuzhou?"

"Is it the research institute that studies aircraft engines?" Ye Fei asked.

608 Institute, the full name is Xia Guo Aviation Zhuzhou Power Machinery Research Institute.

Mainly researches aircraft engines and helicopter reduction transmission systems.

Of course, many other things are studied, but mainly aircraft engines and helicopter reduction transmission systems are studied.

"Yes!" Academician Liu said: "I have already discussed letting you see the research literature on the continuum hypothesis."

"The man's surname is Sun, and his name is Sun Haitian. You go directly to him. When you get to the door of No. 608, call this number. I will send you the phone number immediately, and someone will take you to see Sun Haitian."

"At the same time, you just happen to go to Institute 608 to study. This is one of the postdoctoral mobile stations that gathers a large number of domestic talents."

"Okay!" Ye Fei smiled and said, "Thank you, Academician Liu."

There are only 3,361 postdoctoral mobile stations in the country.

It may seem like a lot, but it covers all disciplines of natural science.

Divide it evenly, it’s not much.

The requirements for entering a postdoctoral mobile station are not very high, but it also depends on what kind of postdoctoral mobile station it is.

Institute 608 is a national-level scientific research institution and one of the five major aircraft engine research institutes in Xia State.

It is not necessary to have a doctorate degree from a non-prestigious university. At least it is from Xia Guo 985 University. Foreign universities are benchmarked against domestic 985 universities.

It's not easy to get into the 608 Institute, let alone get people in, it's even more difficult.

"It's okay!" Academician Liu smiled.

Shortly after hanging up the phone, Ye Fei received a call from Academician Liu.

Ye Fei turned on the computer and looked up Sun Haitian's information from the 608 Institute.

After reading it, Ye Fei sighed: "Another great guy."

Sun Haitian, 62 years old, is a well-known domestic expert in aircraft aerodynamics and experimental fluid dynamics.

He has long been engaged in research on complex flow mechanisms and control of aircraft and research on topological space theory.

Winner of the Outstanding Youth Fund, Changjiang Scholar Distinguished Professor, and academic leader of the National Natural Science Foundation of China’s innovative research group.

He has published more than 400 journal papers, including more than 300 papers included in SCI and more than 50 top journals. He has been continuously selected into the Elsevier Xia National Highly Cited Scholars list and has been invited to report more than 30 times at international conferences.

Won 5 international awards and 10 Xia national awards.

Among all the people Ye Fei knew, except for those academicians, Sun Haitian had the best academic ability.

The next day, Ye Fei said goodbye to his parents, got on a plane and returned to Sand Dunes, and then took a bus to Zhuzhou.

608 entrance!

Ye Fei called the other party according to the phone number provided by Academician Liu.

Soon, a man of about thirty years old walked out of No. 608.

The man walked up to Ye Fei and said with a smile: "Hello, I am Professor Sun's assistant. My name is Yu Jie. I am here to pick you up."

Ye Fei shook hands with the other party and said, "Hello, Ye Fei."

After registering with the guard at the door, the two walked inside.

Yu Jie said: "I will take you to where you live first."

"Okay!" Ye Fei nodded.

The two chatted a lot along the way, but Ye Fei didn't reveal too much personal information.

He just said that he had just graduated from Zhonghu University with a Ph.D.

Yu Jie nodded. Ye Fei looked about twenty-five years old. Although a twenty-five-year-old doctor was rare, it was not unheard of.

After arriving at the residence, they put down their luggage and went to see Professor Sun.

Professor Sun is a middle-aged man with a somewhat plump figure, wearing glasses, with half-white hair and sloppy hair.

When the two entered, Professor Sun was studying the problem seriously.

Yu Jie walked over and said, "Professor Sun, Ye Fei is here."

Professor Sun raised his head and glanced at Ye Fei, pointed to the coffee table and said: "The literature is there, read it yourself."

After that, he continued to immerse himself in his research.

Yu Jie walked to Ye Fei and said with a smile: "Don't mind, Professor Sun has this temper."

Ye Fei nodded. People with weird tempers are too common in academic circles, and Ye Fei was not angry because of Professor Sun's temper.

Moreover, in Ye Fei's opinion, Professor Sun's behavior was too normal and not considered weird.

Besides, he is here to study and seek help from others. There is no need for others to be too enthusiastic towards you.

Even if you have a relationship with Academician Liu, there is no need for people to be enthusiastic about you.

Ye Feidao: "Am I watching here?"

Yu Jie said: "There is an office next door. That's where I work. Just take a look there!"

"good!"

Ye Fei took the documents and went to the office next door.

There were three people in the office, besides Yu Jie, there was a man and a woman. Yu Jie briefly introduced Ye Fei. They and Ye Fei said hello to each other, and then they went about their own business.

"Research on union-closed sets?"

After Ye Fei sat down, he opened the document and read it, thinking in his mind.

There are two major problems in continuum potential, namely the union-closed set problem and the wandering continuum existence problem.

Solving these two difficult problems will prove the continuum potential.

The literature is also divided into two parts, one is the research on union and closed sets, and the other is the research on the existence of wandering continuum.

Ye Fei spent the next few days reading documents.

Professor Sun never came to see Ye Fei, not even a greeting.

Ye Fei also enjoyed his leisure time.

Another week passed, and Ye Fei finally read all the contents of the document.

"Professor Sun is almost finished with the study of union closed sets, and there is only one final step left." Ye Feixin said: "As long as we find n/2 sets, we can prove this problem."

"Let me see if I can prove it."

Ye Fei found paper and pen and started calculating.

Professor Sun put down his pen and said, "It's finally done."

Looking at the nonlinear dynamics chaos theory method he had just completed, Professor Sun felt a little happy.

For a scholar like him, completing each study brings a great sense of accomplishment and pride.

"That's right!" Professor Sun said: "It seems that the director sent someone and asked me to show him the literature on the continuum hypothesis. I wonder how he got it?"

After saying that, he stood up and walked out.

When Yu Jie saw Professor Sun coming in, he quickly stood up and said, "Professor Sun!"

Professor Sun nodded when he saw that Ye Fei was bowing his head and making calculations.

Then he walked to Ye Fei's side to see how he looked.

"Huh..." He suddenly exclaimed and said in surprise: "The last step has been proven?"

Ye Fei heard the voice beside him. He looked up and found that it was Professor Sun. He quickly stood up and said hello: "Hello, Professor Sun!"

"Hello!" Professor Sun nodded: "You actually proved the last step of union closure."

Ye Fei spared the back of his head and said sheepishly: "This is still your credit, Professor Sun. I just completed the last step."

"What's your name?" Professor Sun asked.

"Ye Fei!"

"Oh!" Professor Sun nodded: "Ye Fei, it seems that you have studied set theory quite deeply!"

Although Ye Fei proved several difficult problems in set theory, he is somewhat famous in the set theory circle.

But there are still many people who don’t know Ye Fei.

After all, there are too many scholars in this world. Only by proving the eight major conjectures of mathematics, or winning the Fields Medal or the Nobel Prize can the world know about you.

"Not bad!" Ye Feidao.

Professor Sun nodded: "Do you have any thoughts on the existence of the wandering continuum?"

He discovered that Ye Fei had some talents and wanted to hear Ye Fei's views on the existence of the wandering continuum.

Ye Feidao: "There are two problems with the existence of the wandering continuum. One is that when J() is not connected, for the connected branch of the period, McMullen proved that it can be quasi-conjugated to a polynomial connected Julia set. Do you want to answer this question? It’s been proven.”

"The other is that if J() is not connected, the wandering branch of its Julia set is a single point or a Jordan curve."

"Regarding this issue, I once read a paper called the structure of non-rotated Fatou fields of rational functions and disconnected Julia sets."

"There is a part in it that states that the Julia set is a rational function of the Cantor set and the non-renormalizable polynomial discusses the problem of parabolic point perturbation. I think it is very helpful to this problem."

"Tell me about it!" Professor Sun said with eyes brightening.

"The odd-even behavior 3 of T(n) is a period..."

Professor Sun nodded repeatedly and felt that what Ye Fei said made sense.

Sure enough, mathematics still depends on young people.

Young people have smarter brains than old men like me.

Suddenly, Ye Fei stopped and asked eagerly: "Where's down there?"

"No more!" Ye Fei shook his head and said, "I only want to come here."

"That's all?" Professor Sun said anxiously: "According to your deduction, it's just the last step. How about you study it further?"

"No." Ye Fei shook his head: "No matter how much I study, I can't find anything."

Academics are like this. A problem may block you for a few years, or it may block you for a lifetime.

Professor Sun was itching that the two problems of continuum potential and closed sets had been successfully proved by Ye Fei.

There is also a wandering continuum of existence, which is just one step away.

As long as this last step is proved, the existence of the wandering continuum has been proved successfully.

Then the two problems are put together and the continuum potential proves successful.

The continuum potential has been proved successfully, and it is not far away from proving the continuum hypothesis.

This is Hilbert's first question!

It is very meaningful to prove it, at least to become famous.
