"Good morning, Orange, why did you come to us first today?" Su Mucheng walked into the big office and was seen by Hannah and greeted him warmly.

It is worth mentioning that this Austrian woman is really capable of learning languages. I have only been in school for more than half a month, except for the occasional wrong word, or I forget how to describe a word and have to bring one or two English words, there is no big problem in daily communication.

Even one or two idioms pop up from time to time.

"Hehe, Sister Hannah, of course I miss you." Su Mucheng, who was already in a very good mood, replied, and then said to Liu Chenfeng, who was receiving water: "Brother Liu, Brother Qiao told you to come over." ”

"Oh, what's the matter?" Liu Chenfeng asked with some surprise.

Recently, Qiao Ze has given him all tasks to study papers, and he has not been assigned new tasks for a while, which has made him a little apprehensive. I feel that I am quite useless, and I am afraid that I will be directly proposed to the research group.

No way, Qiao Ze also asked him some thoughts about the subject itself.

But even though he had looked for a lot of supporting papers during this time, the questions given by Qiao Ze were indeed too obscure, and he felt that he needed a sudden burst of inspiration to give his opinion.

He doesn't seem to be inspired.

"You can go over and ask Brother Qiao, hurry up, Brother Qiao is waiting for you, I'll talk to Sister Hannah here." Su Mucheng said with a smile.

No way, the network communication across the ocean is a bit delayed.

The nomenclature in this particular group has always been confusing.

"Hmm." Qiao Ze nodded, then gestured to the location next to him.

And when he first came to the research group, Liu Chenfeng was still quite confident. Although Qiao Ze is very strong, it is a new topic after all, and it happens to coincide with his research. Liu Chenfeng didn't dare to say that he could guide Qiao Ze, but he felt that at least he could keep up with Qiao Ze's rhythm, and everyone was qualified to discuss it together.

"Think about it, if you can solve this problem, we can calculate when the complex N-body system of the solar system will fall apart, which is a problem that Newton failed to solve with all his best efforts in his later years, and this is a problem with the highest value for the continuation of human civilization. And be assured, my team and I are ahead of everyone else in this research, and I'm confident in that, so would you like to? ”

After Qiao Ze glanced at Liu Chenfeng, he calmly introduced.

This is indeed the case, after reading the content sent by Qiao Ze, the little old man pushed his glasses, and then asked a second question.

It is also very good and belongs to the core of Chinese.

Who the hell made José have such a horrible misunderstanding of this world?

"18 years old."

When he's usually fine, he can't find someone who has a mentor at all, okay?

"Haha, you have the humility unique to Chinese people." The little old man commented.

"Little boss, but that's Princeton." Liu Chenfeng couldn't help but emphasize.

For those who don't have math math, it's the mecca of math.

Qiao Ze thought for a moment and replied, "No, it's very superficial. ”

But when he found that Liu Chenfeng's state was obviously wrong, in order to save time and ensure efficiency, Qiao Ze didn't bother to care about him anymore.

With his verbal explanation, Qiao Ze believed that the other party could understand his train of thought.

You can't call Brother Qiao like everyone else, after all, he is much older than Qiao Ze.

Liu Chenfeng came to Qiao Ze's side, sat down a little stiffly, glanced at the screen, and then looked away.

"It's not...... I mean the dean, the dean of the School of Mathematics! Liu Chenfeng's brain, which was already stuck, was not very easy to use in an instant.

What serious mathematician would run to the station to hang a banner when he has nothing to do?

The current editor-in-chief of the Annals of Mathematics is also the dean of the Princeton School of Mathematics, and now the math bigwig wants to video with them in person?

Soon, when Qiao Ze finished writing the whole thought process, he sent it directly.

"Well, little boss, you don't know yet, do you? The editor-in-chief of the Annals of Mathematics is the dean of the Princeton School of Mathematics. ”

Qiao Ze didn't write down the questions on a piece of paper like the other party, but just explained and began to type them on the computer.

Qiao Ze replied, "If they are hit by this sentence, then they must not be very smart. ”

It made him feel a little relatable.

“｛x^μ｝（μ=1，2…… N）。 Σab(a，b，=1，2，…… N) is the generator of the O(N) group to form a constant matrix of NXN, and the following reciprocal relations need to be satisfied......"

On the one hand, the world's top journal papers that are about to be published have his name, and on the other hand, there is the collapse of the logical chain of life.

Accidentally meeting Qiao Ze's confused gaze, Liu Chenfeng hurriedly said.

Wasn't that what he had been hoping for?

When Liu Chenfeng heard this, his whole body trembled.

"Su Mucheng didn't say it?"

The old man on the opposite side picked up a piece of paper and pointed it at the camera, so that he could clearly see the formula and the question given.

In fact, when he first came to the research group, Liu Chenfeng had been very entangled in how to call Qiao Ze.

Rather than buying a bunch of physical textbooks, he prefers to find and read the information he needs directly on the computer.

"Huh?" Liu Chenfeng, whose mind was in chaos, didn't understand what he was going to prepare......

In addition, Qiao Ze usually calls him Brother Liu, so he simply calls him by his first name, which is not rude.

"The other party is connected, ten minutes in advance, you prepare."

"Oh. Our project paper has been submitted to the Annals of Mathematics, and the editor-in-chief wrote back that the paper has met the publication requirements, but there are some things to confirm with the author's video. You're a three-piece, so let you show your face. ”

This chapter is not over, please click on the next page to continue reading!

Originally, Qiao Ze still wanted Liu Chenfeng to say a few words to the other party.

"Little boss, is there something wrong?"

As for Qiao Ze, he is still called Brother Liu.

No way, the guy next to me seems to have suddenly lost his ability to speak.

The brain is completely confused, and the ability to think has almost been lost.

Qiao Ze glanced at it, and it was the video software installed just now that came to the signal.

"No, I don't. She said I'll find out when I come over. ”

……

"18 years old?" The little old man in the video pushes his glasses, as if thinking about something.

I didn't tell Liu Chenfeng directly because it was a great thing.

Before coming to the research group, he still has to help his supervisor take those dumb graduate students, okay?

Qiao Ze glanced at Liu Chenfeng and found that this guy was still in a dazed state, so he could only explain by himself: "If E^N is an N dimensional European space......"

Qiao Ze began to observe the bookcase that leaked in the video, well, the books were very messy, and he was an old man who didn't like to pick up.

"I like you, haha...... Joe, I really like you. By the way, the topic I'm working on is the N-body problem, which is a big mathematical problem that got Newton into thinking about theology in his later years. If you are also interested in the N-body problem, I would be very happy to welcome you to Princeton to work on this problem with my team. While I may not see any hope of a real solution to this problem in my lifetime, there is certainly hope for you at this young age. ”

Famous Chinese mathematicians, such as Chern Shiingshen, Tsung-Dao Lee, and Chen-Ning Yang, all taught at the Institute for Advanced Study in Princeton.

It's nice to have a dean as a mentor, but free up a lot of time to help him with chores?

Because he doesn't really like to put everything in order.

"Hmm." Qiao Ze glanced sideways at Liu Chenfeng, a little strange.

Qiao Ze's dull temperament is extremely dull, and it is difficult to get close to other people. So if something good happens, Su Mucheng will always create an opportunity for Qiao Ze to tell others in person, and if something bad happens, she will announce it.

is only the dean of the School of Mathematics, and there is also one at Xilin University of Technology, and he is also the mentor of the one next to him. Often doing meaningless things and saying boring ideas, in Qiao Ze's opinion, only people who have nothing to do every day will have so many strange ideas.

The smile on Su Mucheng's face calmed his nervous mood a little.

The questions asked by the other party are very tricky and go straight to the core.

Looking at Liu Chenfeng's stunned appearance, Qiao Ze shook his head slightly, and couldn't help but say, "Don't think about what others are doing." It's good that you have a dean's tutor here, although he may not help you academically, but he is usually very idle, and he will definitely free up a lot of time to help you deal with those non-academic things, so that you can only think about academic progress, which is your advantage. ”

"Hmm...... Hahaha......"

"Isn't your mentor also the dean of the School of Mathematics?" José was even more confused.

The younger generation of Tao Shen is known for his Ph.D. in Princeton.

"Hello." Qiao Ze greeted.

It turned out that this was not the case.

He was sure he heard it right, but it was a gracious invitation from the dean of the Princeton School of Numbers.

But he didn't have that many books.

But the next moment I started to get excited again.

It seems that the important thing is not who the editor-in-chief of the Annals of Mathematics is, but that the paper has been almost confirmed to be published in this top mathematics journal, and he is still the third author.

The occasional comments and discussions give Qiao Ze a little different. This little old man does have something, although it is only based on the paper itself, and there is not much that can be felt, but some of the ideas are very bold and quite interesting.

Because it would have to wait a while, Qiao Ze had already switched to his smart assistant.

This sentence made the little old man on the opposite side obviously stunned for a moment, then pushed his glasses and said, "Really, you will hit many people if you say this." ”

Smiling so brightly shouldn't be a bad thing.

There is also a "Mathematics Yearbook" in China, which is divided into two series, A and B, A is a bimonthly in Chinese, and B is an English quarterly.

Liu Chenfeng just wanted to explain to Qiao Ze that this world is not like this, when the computer's speaker suddenly made a "beep" sound.

Qiao Ze felt that the other party might have some misunderstanding, and explained seriously: "No, I won't be modest. My understanding of group theory is only adequate, not deep. Just like my understanding of geometry, it's sufficient, but it's also not deep. ”

Anyway, in a sense, Qiao Ze is indeed his little boss, after all, he can get money in the research group, although it is not much, but it is more than 3,000 yuan per month.

The three views began to crumble at this moment.

"I'm Qiao Ze, he is Liu Chenfeng of the research group, and he is also the third author of the paper."

Hearing this solicitation, Liu Chenfeng, who had been silent, looked at Qiao Ze in astonishment as if he had suddenly been woken up.

The question-and-answer process lasted about an hour.

"Little boss, are you looking for me?" Knocking on the door and walking into Qiao Ze's office, Liu Chenfeng greeted politely.

After about a second or more, the voice of the other party came from the other side: "Oh, hello, are you a team?" So who is the first author of this paper, Josser? ”

Is this the other way around?

So what kind of tiger and wolf words are this?

"The editor-in-chief of Princeton's Annals of Mathematics wants to video with us?" Liu Chenfeng confirmed it again, his voice trembling slightly.

"Well, Joe, I'm sure this is indeed your paper alone. It's an interesting and novel discussion for me, you know? I haven't had such an in-depth discussion with a young mathematician like you in at least twenty years. Your mathematical thinking has been an eye-opener for me. By the way, you still have research on group theory, and do you think so deeply about group theory? ”

This chapter is not over, please click on the next page to continue reading!

In order to publish a paper, he just had a few video chats with an editor-in-chief, and he didn't quite understand why Liu Chenfeng was so excited.

"Huh? The dissertation has already been completed? Annals of Mathematics? Is it the one from Shuangdan University? ”

Qiao Ze shook his head and said, "It's the Princeton one." ”

"Oh, you mean he's idle too?" Qiao Ze asked casually.

In particular, it was fun to communicate with the little old man in the video.

Finally, after discussing why the final result of the paper could not be reduced to Maxwell field, the little old man smiled happily.

"So what?" Qiao Ze asked.

"Well, I have to say it was a surprise to me. So let's start with the proof of the first lemma, let's take a look at this passive Yang-Mills equation that you listed...... Now please give me a reason and tell me about your thought process for this step. ”

After all, that's Princeton, the place where legend has mass-produced Fields Medal winners, and 26 Fields winners in history have graduated from this university.

"Unbelievable, you know, Joe, you seem young enough to take the liberty of asking a more personal question? How old are you? ”

Later, after discovering that he couldn't even keep up with Qiao Ze's leapfrogging thinking mode, he really couldn't call his name directly, so he simply learned Tan Jingrong's direct call for the little boss.

"Ahem...... Actually......"

Soon, a small old man with round glasses appeared in the video opposite.

"So......" Liu Chenfeng raised his hand and scratched his head, suddenly feeling so excited that it seemed to be unreasonable. Because he can't give a reason.

Qiao Ze had also switched to the video conferencing software sent by the other party, and clicked the "connect" button on the invitation dialog box in the lower left corner.

glanced at Qiao Ze carefully, his expression was serious, it really didn't look like he was joking.

Qiao Ze's answer made the old man opposite stunned for a while, and then suddenly burst into laughter, and he couldn't stop it.

"Oh, okay." Liu Chenfeng hurriedly took a sip of water, and then rushed over.

After Qiao Ze finished his introduction, the old man in the video seemed a little surprised a moment later.
