"There are 52 people who gave academic reports in the mathematics lecture hall of this forum." Dong Siyuan held his mobile phone and checked the official website of the forum: "You are the fifth from the bottom." ”

"So, today and tomorrow, it's none of your business, it's almost the afternoon of the day after tomorrow, and I will get to you."

Ye Fei nodded, this is fine, he can listen to the report with peace of mind for two and a half days, and he can learn a lot of knowledge.

At around two o'clock, the host came to the stage to introduce the leaders present.

The leaders are all mathematics professors and politicians from well-known universities in the magic capital. Government personnel.

Then the leaders came to the stage to speak and said a lot of official face-to-face speeches.

Ye Fei, who listened to it, was sleepy, from childhood to adulthood, what annoyed him the most was the leader's speech.

The key is that these leaders still spoke for dozens of minutes.

I don't think about the audience at all, and no one really wants to hear the leader say a lot of nonsense.

At around three o'clock, the leader's speech finally ended, and some scholars began to take the stage to make academic reports.

Ye Fei cheered up and began to listen to the academic report.

"It's the right time to come to this academic report." At six o'clock in the evening, I left the lecture hall and walked towards the hotel.

"These scholars are from top universities and research institutes in many countries in Asia."

"They themselves are some of the best young mathematicians in Asia."

"Their mentors are world-renowned mathematicians."

"There's a lot to learn from them."

Ye Fei looked at the system, and the progress of the task had reached 68%.

Before coming, mission progress is 50%.

In just three hours, he increased his mission progress by 8%.

"If you say an 8% increase in three hours, it's almost a 2.6% increase in one hour."

"Then in the next few days, you can listen to the 17-hour report meeting, then the task can be increased by 44.2%."

Ye Fei was taken aback by this progress: "If it is calculated according to this, it is not until the forum is listened to, and the progress of the task reaches 94.2%. ”

"A forum, the task is almost complete."

"Then should I go back and do research with my mentor?"

"Isn't it possible that I haven't gone back yet, and the problem of the Tiny Tower has been proven by me?"

"That's not right!" Ye Fei shook his head: "The progress of scientific research cannot be calculated in equal proportion mathematics, and the more difficult the research is, the slower the progress will be." ”

"But no matter how slow it is, the mission should be 80% progressive."

"Ye Fei, let's go, I'll take you to a fun place." Dong Siyuan said with a smile.

"We're not going to eat?" Ye Fei said in surprise.

After listening to the report meeting for a long time, I was hungry.

"Ye Fei, you have to remember that this kind of activity is not only for you to listen to the report, but more importantly, for you to make friends."

"In academic circles, ability is very important, and connections are also very important."

"Especially in the Xia Kingdom, connections are our national condition."

"Wide network of people is very convenient for the exchange of knowledge, scientific research cooperation, striving for scientific research funds and job promotion."

"Even the selection of academicians is a competition for connections."

Dong Siyuan looked around cautiously and whispered: "In the academic circle, some people are well-connected and don't have many real talents, but they are also very popular. ”

"In this era, it is to laugh at the poor and not at the prostitute."

"Eight immortals cross the sea, each showing their magical powers!"

"As long as you mix up, others don't care if you have real talent or not."

"Of course, only the real bigwigs can ignore everything."

"For example, Yau Chengtong, who won the Fields Medal, Qiu Lao."

"He is a network and a scientific research center, and he wants a position and scientific research funds, which he can get at his fingertips."

"When others send it to him, it depends on whether he likes to take it or not."

"But we are not Qiu Lao after all, and no one in the entire Xia Kingdom can compare with him."

"He can ignore all this, but we can't."

Ye Fei nodded.

"I'll take you to meet some people." Dong Siyuan said with a smile.

"Senior, don't say my name, after all, you also know that there are many people who are here for me, and I don't want to attract attention."

"Okay!" Dong Siyuan thought for a while and said, "Then I'll say that you are my junior brother, so I won't say your name." ”

"Okay!"

Soon, they entered a hall where a party was going on.

In the middle is a long table with lots of food on it.

All the young scholars mingled in the hall with plates or glasses.

Dong Siyuan stepped forward to talk to someone he knew, and when he introduced Ye Fei, he said that he was a junior brother to recognize the world.

Those present were not only engaged in mathematics, but also physics, chemistry, materials and energy.

Various disciplines are mixed with exchanges, and various ideas collide.

Among them, there is also an exchange on set theory, and Ye Fei occasionally interjects a sentence next to him, often in one sentence, which attracts attention.

But they just glanced at Ye Fei and marveled at his ingenuity, and then they continued to communicate with others.

Next, the first and second days are the same.

The time came to the third day, and this afternoon, it was Ye Fei who came to power.

At this point, he is 85% progress in his mission.

And today's audience is also the largest in the past few days, after all, many people are coming for Ye Fei.

According to the list on the official website of the forum, Ye Fei took the stage on the afternoon of the third day.

At around four o'clock in the afternoon, the host walked up to the stage and said, "Welcome Ye Fei from Zhonghu University!" ”

"Bang Bang Bang ......"

In the warm applause, Ye Fei walked on stage.

"Is that him?"

Many people were surprised when they saw Ye Fei.

Because at the dinner party in the past two days, they saw Ye Fei.

Many people thought Ye Fei was very clever at the time, but they didn't expect this person to be Ye Fei, no wonder there are many novel ideas about set theory.

Some people regret not having a good chat with Ye Fei, after all, Ye Fei proved that he had a singular cardinality, and his ability was very strong, and he would definitely have a place in the mathematical world in the future.

For such a person, you should make friends with him and expand your network.

Of course, there are also many people who marvel at Ye Fei's youth, as the legend says, he looks only about 22 years old, just like an ordinary college student.

Ye Fei stepped onto the stage and said, "Hello everyone, I'm Ye Fei." ”

Then he began to explain the singular cardinality, writing down the steps of proof on the whiteboard as he did.

At the same time, through the camera, it is displayed on a large LCD screen.

This way, everyone in the room can see what is on the whiteboard.

[There are two graphs G1 and G2, with vertices V=V (i=0,1,1,...,j=0,1,2,...) ……】

Most of the people present looked confused.

"...... I don't understand ......."

"What is that talking about?"

"It's so profound, I spent a month studying his paper beforehand, but I still don't understand it."

"I'm a Ph.D. in mathematics from Mizuki University, and I can't understand the dissertation of a last-class 985 Ph.D. student, it's a dog."

"I'm a Ph.D. in mathematics from the University of Tokyo, and I can't understand the mathematical proof process of a Xia Guo scholar, Amaterasu!"

“……”

Ye Fei was lecturing for the first time and had no experience, so only those who had a deep study of set theory could understand what he was talking about.

And only a very small number of these people were present.

Dong Siyuan found out about this because he couldn't understand it either.

He sent a WeChat message to Ye Fei and asked Ye Fei to say it as simple as possible.

Ye Fei can only try to simplify the content as much as possible so that more people can understand it.

But this is where the problem arises, and I want to simplify the content so that more people can understand it.

Then the amount of content to be said should be increased, starting from the bottom.

For example, 2x2 cannot be said to be 2x2, but to say 1+1+1+1+1.

From the simplest content, layer by layer, so that the quantity of content is simplified and the quality is simplified.

When Ye Fei changed his way of thinking, many people present took a long breath and finally understood.

This also shocked many people, but they didn't expect Ye Fei's young age to be stronger than them.

Sure enough, it's not acceptable!

There are also many who are amazed that this is a mathematical genius.

Mathematics wants to study deeply, and only a genius can do it.

Half an hour later!

Ye Feidao: "When A is included in B, where A has a strong finite exchange property, then A is equal to B......"

Suddenly, Ye Fei was stunned, and recalled in his mind what he had just said, A is equal to B.

"A equals B......"

All the knowledge in the brain is integrated, and a set of proof formulas is slowly formed.

Seeing Ye Fei's sluggish expression and no longer speaking, many people looked at each other suspiciously, discussed with each other, and guessed what happened to Ye Fei.

The scene became noisy.

Dong Siyuan looked at Ye Fei worriedly, and he didn't know what was wrong with Ye Fei.

The host wanted to come to the stage to remind Ye Fei and let him continue to speak.

But before the host came to the stage, a middle-aged man sitting in the leadership seat waved his hand to stop the host.

The middle-aged man is from Fudan University, a professor of mathematics in the Department of Mathematics of Fudan University, and a doctoral supervisor.

He is one of the top mathematicians in China, mainly researching recursive theory and mathematical logic.

Set theory is also one of his studies.

He knew that Ye Feilai was coming, so he came to the forum as a leader to hear the young man who had recently become famous and his proof of the singular cardinality.

He looked at Ye Fei in surprise and exclaimed: "This is a natural mathematician, just giving a lecture, he burst out of inspiration." ”

Others couldn't see it, but he could see that Ye Fei was inspired.

Don't bother him at this time, or the inspiration will be broken.

After a long time, Ye Fei raised his head and said with a smile: "I'm sorry, I just thought of some questions, so let's continue to explain." ”

Ten minutes later, the presentation ended!

After that, there were questions, and Ye Fei also answered them perfectly one by one.

When Ye Fei was about to step down, Professor Fudan asked, "Ye Fei, can I ask, what were you thinking about just now?" ”

Ye Fei looked at the professor and said, "In the problem of the smallest tower, p=t." ”

"Woo......" exclaimed many people present.

The problem of the smallest tower is one of the core problems of set theory.

There are two major problems in it, p=t and proving p=t under ZFC.

If p=t is proved, three-quarters of the minimum tower problem is completed, and it is not far from proving the minimum tower problem.

The professor was surprised, "What you said is true?" ”

The professor had previously demonstrated the problem of very small towers, but without success.

But this was not a reason for him to be surprised, you must know that Ye Fei only proved the strange base number a month and a half ago.

After a month and a half, it was proved that p=t?

The time is too short, the speed is too fast.

Cantor couldn't even be reborn.

Not only did the professor not believe it, but everyone present did not believe it.

"You can follow my Arxiv, I'll go back to writing my paper now, and you'll be able to see my first draft in two hours."

Regarding the paper p=t, Ye Fei has started writing it a long time ago, but the core part has not been proved, that is, the proof formula of p=t.

Now fill in the core sections and the paper is complete.

Besides, this is just a first draft and doesn't need to be written too formally.

After all, there are many revisions to be made later.

After speaking, Ye Fei left the lecture hall.

Many people present were shocked, could it be that Ye Fei really proved p=t?

They didn't have the heart to listen to the next report.

A lot of people are leaving!

The remaining four people who made academic reports looked helpless after watching the audience walk more than halfway.
