From university academician to chief academician

At night, Ye Fei lay on the bed and turned on the system.

[Task: None

Physical fitness: 150

IQ: 129

Function: Comprehension: Lv0(0/100)

Level: 0

Points: 105]

Ye Fei has completed two tasks, the first task earned 5 points, and the second task earned 100 points.

But he never added points, because one point for physical fitness and IQ required one hundred points, and one point for function required ten points.

The points he has gained now, adding a little physical fitness or IQ will help him negligibly, and the functions cannot be upgraded. Failure to upgrade and improve them is equivalent to nothing.

So he kept saving his points.

"Singular Cardinality has proven successful and the next mission can begin."

“My mentor has been urging me to collaborate with him on the minimal tower problem.”

"Now that I have nothing to do, let's study the minimal tower problem!"

The minimal tower problem appeared in 1940 and is one of the core issues in set theory.

The question is whether the two continuum cardinal invariants p and t can be proved to be equal under ZFC.

This problem is the oldest open problem in cardinal invariant theory.

If proven successful, it will play a huge role in promoting the development of force theory.

ZFC, the full name is ZFC axiom system.

It is the ZF system proposed by Zermelo and Frenkel. On this basis, the axiom of choice is added to form the ZFC axiom system.

It is the first axiomatic set theory system and has very wide applications in set theory.

The forcing theory, also called the forcing method, is an important method for constructing extended models in the study of axiomatic set theory. It was founded by Cohen in 1963 to prove the independence of the continuum hypothesis.

To put it bluntly, whether it is a singular cardinality problem or a minimal tower problem, it is very helpful to prove the continuum hypothesis.

Ye Fei said setting up the task.

[Task: Prove the Minimal Tower Problem

Details: Whether the two continuum cardinal invariants p and t are provable to be equal under ZFC

Reward: 100 points]

"Another 100 points? It seems the difficulty is the same as the singularity base."

Starting from the second day, Ye Fei and Lu Yishan studied the minimal tower problem together.

After Ye Fei fully studied Professor Lu Yishan's previous research, he made some additions. The cooperation between the two made the research speed very fast.

Ye Feidu sighed: "It's true that fighting alone is not as fast as working with two people."

It used to take two months to study singular bases by myself, but if two people cooperate, the speed will be greatly improved.

Ye Feixin said: "At this speed, it will take up to two months to prove it."

Professor Lu was very surprised. He didn't know if he didn't cooperate. He was shocked when he cooperated.

"Is this a mentor leading a student? Or is a student leading a mentor?"

Many of Ye Fei's ideas are very novel. If he hadn't studied the problem of minimal towers for many years and had a profound foundation, he would have almost been unable to keep up with Ye Fei's pace.

Professor Lu was in pain and happy.

The happy thing is that the research speed is very fast, but the painful thing is that he can hardly keep up with Ye Fei's rhythm and needs to supplement his knowledge.

"No, I can't work twelve hours a day, so just work six hours. I still have six hours left to study."

Professor Lu was forced to have no choice, otherwise he would really be unable to keep up with Ye Fei's pace.

Originally, he wanted to drag Ye Fei to join his project and let Ye Fei follow his own pace.

It's better now, because he has to follow Ye Fei's rhythm.

But the rhythm seemed to be out of reach. He had to slow down the pace, have time to study every day, and try his best to keep up with Ye Fei's rhythm.

"Why didn't you know he was so perverted before?" Professor Lu complained in his mind: "If Ye Fei knew about my abilities, would he look down on me?"

"No, your ability must not be seen."

Ye Feishi did not see Professor Lu's ability.

First, there is little experience.

Second, the cooperation time is short.

The third is that I am too involved in research and have no energy to pay attention.

Fourth, he himself is studying and researching at the same time, and his background is shallow.

"Professor Lu's ability is quite strong. Many of his views cannot be learned online. They are his private treasures. But after I studied, I learned the knowledge online, which helped me even more."

In the blink of an eye, a week has passed, and tomorrow is the day for the International Forum of Young Scientists.

Professor Lu took a long breath. Ye Fei was going to participate in the forum these days. He would use these days to supplement his knowledge, otherwise he was afraid of holding Ye Fei back.

November 16, morning, at the gate of Zhonghu University.

Professor Lu and Ye Fei were standing at the school gate. Suddenly, Professor Lu waved his hand and said: "This..."

Soon, a young man about thirty years old came over.

The young man looked very gentle, with fair skin, tall and thin, wearing a pair of glasses, holding a black briefcase in his hand, and wearing a suit.

"Professor Lu!" The young man walked up to Professor Lu and said.

Then he looked at Ye Fei and said with a smile: "You must be Ye Fei. I've heard your name in the past few days and I've become calloused."

He stretched out his hand and said: "Hello, my name is Dong Siyuan."

"Hello!" Ye Fei shook hands with him.

Professor Lu said: "Ye Fei, Dong Siyuan also graduated from the mathematics department of our school. He is a student of Professor Liu Yisheng. This time he will go to the forum with you."

Ye Fei smiled and said: "Hello, senior, I will ask for your help next time."

Dong Siyuan smiled and said: "Wherever you go, I will be a guide. The forum is your stage."

"Okay." Professor Lu said, "Stop talking nonsense, you have to catch a flight, go quickly!"

While Ye Fei was not paying attention, Professor Lu quietly said to Dong Siyuan: "Try to come back as late as possible."

Dong Siyuan was startled and didn't understand what Professor Lu meant.

But Professor Lu did not explain and urged them to hurry up.

More than three hours later, they checked into a hotel near the International Forum. The hotel had been booked by the forum, and all scholars could stay for free by showing their invitation letters.

Dong Siyuan said: "Forty-five countries and more than a thousand scholars are participating in the forum this time. Almost all countries in Asia have participated."

"The forum is divided into five lecture halls, namely mathematics, physics, biology, materials and energy."

At 1:30 in the afternoon, they arrived at the forum on time. After the doorman read the invitation, they walked to the mathematics lecture hall.

Dong Siyuan said: "Generally, there are not too many people coming to participate in mathematics forums. A hundred people would be considered good."

"Why are there so few people?" Ye Fei asked, "Isn't mathematics the mother of all subjects?"

"It is the mother of all subjects." Dong Siyuan nodded: "But other subjects can see more practical things than mathematics."

"For example, aerodynamics in physics can help the development of the aviation industry."

"But mathematics is there to help develop aerodynamics."

"So, people want to see something practical rather than a set of numbers or formulas."

"Unless there is a major breakthrough in mathematics, it will attract a lot of attention."

Ye Fei nodded.

While talking, they came to the door of the mathematics lecture hall, then pushed the door open and entered.

"Uh..." Ye Fei looked at the lecture hall in shock.

There were more than 500 people in the lecture hall at this time.

Ye Fei asked in surprise: "Senior, there seem to be more than a hundred people here!"

Dong Siyuan nodded and said: "It seems so, maybe there is some accident!"

He pulled a young man next to him and asked, "Hello, why are there so many people today?"

The young man looked at Dong Siyuan blankly and asked, "You don't know?"

"What do you know?" Dong Siyuan asked doubtfully.

"Ye Fei!" The young man said: "We heard that Ye Fei was going to give a report, so we all wanted to come and see him. We heard that he is only 22 years old this year. We just want to confirm whether this is the case."

"The people present are all from the top universities and research institutes in Asia, and a small number of them are from the Americas and Europe."

"We are all young people, and we are not convinced that he can achieve such achievements at the age of 22."

After the young man left, Dong Siyuan looked at Ye Fei with some laughter and tears: "It seems that you are under a lot of pressure today!"

Ye Fei smiled bitterly and shook his head: "I didn't even expect it to be like this."

They randomly found a place to sit down, and in order not to attract attention, they found a corner to sit down.
