Scholar's Cultivation System Panel

Perhaps because the big bed in the room was so comfortable, Xu Yunyuan did not suffer from insomnia on the first night overseas, but the food provided by the hotel in the morning was not very palatable.

Hofer still came here on time, and after picking up Xu Yun, he drove directly to Princeton University.

According to the previously determined process, the most important part of this exchange is the open class.

There will be students from Princeton University, as well as professors who will come to listen to the lecture and ask questions for discussion.

At any rate, Xu Yun held an academic report meeting, and also held an open class in the Department of Mathematics of Peking University, so there is nothing to worry about on the way.

On the contrary, because he was about to meet Professor Deligne, he felt a little excited and excited.

As for the most authoritative people in the mathematics world, Deligne, as the winner of the Fields Medal, the Wolf Prize in Mathematics and the Abel Prize, can definitely be called one of them.

Being able to communicate and discuss with such characters will also be of great help to my own research.

Although the other party had a video connection at the Hodge Conjecture report last time, they did not actually discuss a few words.

Now that I finally have the opportunity to meet, I must make good use of it.

The buildings of Princeton University are relatively old, and entering the interior seems to be in an ancient castle that exists only in fairy tales.

Blue sky and white clouds.

Full of heavy historical atmosphere.

Under the leadership of Hofer, it didn't take long for Xu Yun to enter a building that looked like a castle, and successfully met Professor Deligne and Professor Witten, who also won the Fields Medal.

"We meet again. I have been waiting for this day for a long time."

The image of a kind little old man, Deligne, saw Xu Yun, and immediately stepped forward to give him a polite hug.

And after letting go of Xu Yun, he immediately introduced the person next to him.

"Let me introduce you, this is Professor Witten from our Princeton Institute for Advanced Study."

"And Professor Veitch from the Department of Mathematics."

Facing the enthusiasm shown by Deligne, Xu Yun greeted Witten and Vicky who were also aged next to him.

Reached out and shook hands with each of them.

At this time, Hofer saw that his task was successfully completed, so he didn't intend to stay and disturb too much.

"Then you guys should have a good communication, and I will go back to work in the editorial department as soon as possible." Hofer finished this sentence with a smile on his face, and then turned his gaze to Xu Yun and said, "I am looking forward to your work." I hope to see that new paper in my mailbox soon, regardless of whether the content of this paper is a demonstration of topological group theory."

"I will, Mr. Hofer." Xu Yun nodded and replied.

The conversation between the two also allowed Deligne and Witten to capture the information, and a little curiosity suddenly appeared in their eyes.

I want to know which direction the new paper Xu Yun is talking about will go.

After all, no matter which paper Xu Yun published in the Annual Journal of Mathematics, it caused a great sensation in the mathematics world.

But since Xu Yun didn't make it clear, they didn't take the initiative to ask.

After several people sat down again and Witten made a few cups of hand-ground coffee, they continued talking.

"I was surprised when I saw your paper proving that there are infinite prime numbers in the Fibonacci sequence. I really didn't expect you to have such a deep research on algebraic geometry and logarithm theory."

"Especially the topological group theory proposed in the paper is really eye-catching."

Deligne, who picked up the coffee, was the first to open the topic, and there was a hint of surprise in his eyes when he said this.

His field of expertise is algebraic geometry, and his teacher is even called the emperor of algebra.

Under normal circumstances, algebra alone is extremely profound, and many people need to spend a lot of time exploring it.

It is even possible that you will not be able to grasp all of them until you die.

And solving the Hodge conjecture is an unimaginable workload.

After all, in addition to algebraic geometry, Hodge's conjecture also includes topology and mathematical analysis.

In his opinion, Xu Yun's ability to prove Hodge's conjecture must be due to spending a lot of time on research.

In this case, even if it is serious, he thinks it is normal.

But Xu Yun created a miracle again.

He made his mark in the field of number theory.

He has studied mathematics for decades and has seen many mathematical geniuses, but none of them can reach Xu Yun's level.

It was under such circumstances that he tried his best to invite Xu Yun over.

"I also became interested in number theory by accident, and only then did I try to conduct in-depth research."

"I didn't expect to have some new discoveries."

Facing the senior figures in the mathematics world, Xu Yun spoke modestly and answered Deligne's question.

"It's a good thing that a genius like you can appear in the world of mathematics!" Witten couldn't help echoing at this time.

But when the three of them were communicating harmoniously, the relatively unfamiliar Vicky suddenly spoke up.

"I am very interested in your topological group theory, can I ask how far you have proved it so far?"

"Professor Vitch's research is in the field of number theory." Next to him, Witten helped explain.

When Xu Yun heard the other party mention topological group theory, he thought that he had already proved Goldbach's conjecture, so there was no need to hide anything about it.

Instantly open your mouth and answer truthfully.

"I have done a proof about topological group theory."

"The proof is complete?"

"This is impossible."

Wei Qi, who was still waiting for the result with a calm face, immediately pulled down when he heard the answer.

Doubt was written all over his face.

He has studied the topological group theory in depth, although it was proposed by Xu Yun, it has never been proved.

Therefore, he believes that topological group theory cannot be established.

It is even less likely to be used for proofs of famous problems in number theory.

But now Xu Yun told him that the topological group theory has been proven, almost equivalent to destroying his worldview.

Some of Deligne and Witten were deeply surprised, once again shocked by Xu Yun's talent.

"It's unimaginable. I'm afraid the strongest genius in history can only reach this level."

"It seems that your talent in number theory is higher than in algebra."

As a result, the voice was interrupted by Vicky, who was a little out of shape, before he could finish speaking.

"I have consulted many scholars about your topological group theory, and it is the result of our mutual approval that it cannot be established."

"It's absolutely impossible to prove."

Suddenly being questioned, Xu Yun was also very helpless, and really didn't know what to say.

If you tell the other party that you have not only proved topological group theory, but also solved Goldbach's conjecture with topological group theory, you don't know how the other party feels.

But after all, as a guest on other people's territory, it is definitely not easy to tear your face.

So Xu Yun still answered calmly.

"Professor Vitch."

"I did complete the proof not long ago of topological group theory."

"I will intercept the explanation of this public class. If Professor Weiqi has any questions, you can come and listen."

"Everyone communicates with each other."

Hearing that Xu Yun was going to talk about topological group theory, Deligne immediately became interested and quickly answered.

"You are going to give a lecture on topological group theory in the open class, then I will go to listen to it."

"If the number theory community knows the news, they will rush to Princeton as soon as possible." Witten took Deligne's words and replied with a smile.

Soon Vicky's mood also stabilized, but he still maintained his point of view.

"I'll be there on time."

Anyway, I have studied number theory for so many years, and I have professors and scholars in the circle to support my judgment. I will definitely not easily believe that topological group theory can be proved.

Otherwise, wouldn't it mean that his research has no value.

In his opinion, the so-called proof that Xu Yun said should be a false proof. As long as he is on the scene, he will definitely be able to find a way to overthrow the proof, so there is no need to argue now.

The mathematics community can only rely on its own strength.

Xu Yun could still remember what Wu Zhongping told him when he arrived. Since he wanted to show his level in front of the students of Princeton University, the content of ordinary public lectures seemed relatively ordinary.

No matter from which point of view, topological group theory is the most appropriate.

After all, he couldn't prove Goldbach's conjecture on the spot.

Soon Deligne seemed to think of something again, and asked again: "I don't know when you plan to start this public class?"

"Anytime." Xu Yun replied.

Whether it's the proof of Goldbach's conjecture or topological groups, everything is in his mind.

There is no preparation for what to say.

Simply put, basically four words.

Come at your fingertips.

Deligne naturally supported this, and after a little thought, he decided on the specific time.

"Then how about tomorrow afternoon?"

"Can."

"In this case, you can go around the campus today, or you can go to other places if you want, and I will arrange my students to cooperate with you." Deligne immediately replied after receiving Xu Yun's affirmative answer.

Naturally, Xu Yun would not refuse such kindness, who made him come to Princeton University for the first time.

It is undoubtedly more convenient to be accompanied by someone who wants to understand the culture of this school.

"Thank you Professor Deligne."

After thanking Deligne again, Professor Witten next to him suddenly burst into a hearty laugh.

"I think tomorrow is very likely to usher in an open class with the largest number of students in the school."

"I am looking forward."

...

After confirming the time and content of the open class exchange, Xu Yun came out from Deligne Witten, and it didn't take long for him to successfully meet with Deligne's students.

Under the leadership of the other party, I can appreciate the architecture and environment of Princeton University.

During the process, I did not forget to take photos to share with Chen Shihe after returning home.

It is also worth mentioning that Xu Yun did not return to the hotel at night, but lived in a room in an ancient castle building in the school.

the next afternoon.

As Professor Witten predicted, the largest classroom was already full of people before the open class started.

Many people even chose to stand and listen.

Looking around, except for a few foreign students, the number of professors is also not small.

It also includes Deligne and Witten and that Vicki.

The main reason is that Xu Yun, as the most outstanding genius in the mathematics field in recent years, has independently proved Hodge's conjecture, and has become an idol in the hearts of many students who study mathematics.

How can I miss such a hard-won opportunity to come to Princeton University for academic exchanges across the sea.

What's more, apart from being very young and talented, this genius is also very handsome in appearance. Naturally, everyone wants to see the real person with his own eyes.
