Princeton, USA.

For this town, entering September already means the arrival of autumn, especially at night, which has been less hot and cooler than August.

When Lott Dugan walked out of the office, he wore a thin coat.

The maple leaves on the path outside the school were already stained red, and the street lamps between the branches and leaves were emitting a dim glow.

The quaint English architectural style teaching building can only see a hazy shadow under the dim light, which is more beautiful.

The surroundings are quiet and the air is fresh, perfect for a wonderful environment for thinking.

All of this made Lott Duggan feel a little annoyed.

He really hoped that the 18-year-old guy in China could come to see the beauty of this place and experience the academic atmosphere here, and he felt that if Qiao Ze came, he would definitely be inseparable from here.

Unfortunately, his invitation was outright refused.

The other party didn't even hesitate for a few seconds to show respect, and gave a direct answer.

What made Liu Chenfeng even more speechless was that Qiao Ze seemed to feel that these were all things that the old man on the other side should do, and he didn't even feel honored at all.

Both invited each other once, and both turned each other down.

"That's what you should do at your age, I'll send you the exercises later, just wait."

This is probably the law of conservation of mood.

"No, I just don't want to. In addition, I also have a proposition that I want to solve, about the mass gap hypothesis, if I want to solve the N-body problem, I will definitely be interested in this problem. And I can feel that your level is very high, higher than many of the professors I've been in contact with so far. If you can come to our Xilin University, you will definitely get the respect you deserve. ”

"What? Has Qiao Ze's new application been completed? Is it also confirmed that the paper will be published in the Annals of Mathematics? Liu Chenfeng, this matter is very serious, don't joke! ”

Probably everything in this world has to follow the law of conservation, right? For example, when a person's mood starts to improve, there must be some people who start to be in a bad mood, which is the true meaning of this world.

"Oh, then you keep trying." Qiao Ze casually encouraged.

"No, everything should be for a reason. Tell me, do you have any concerns? Trust me, if you are willing to come, I will give you a perfect research environment. ”

There was silence on the other side.

It's as if the current dean of the School of Mathematics is not his mentor, but him.

"Green, how did you finish the question you gave you last time?"

Liu Chenfeng felt that he had not been able to establish too much friendship with Qiao Ze, and the research group was disbanded.

"Dust wind? You've been floating lately, haven't you? Don't know what I hate most about Riddler? Have you learned to sell off in front of me? Jozer has written so many papers, which one are you talking about? Where's the hell? ”

For Liu Chenfeng, it is indeed not in the way to be able to follow Qiao Ze even if he is postponed for two years.

Forget it, he can't dream anymore, it will make him feel that reality is cruel.

Really, if the old man on the other side of the video was so good to him......

At the graduate level, you can independently publish the top papers in the second district, or the three works of several top journal papers, and write these into your resume, which tutor can't look at it? It is no exaggeration to say that at least half of the mathematics doctoral supervisors in many domestic colleges and universities are probably at this level

So Liu Chenfeng did not go back to the big office of the research group directly, but directly dialed Xu Dajiang's phone in the corridor: "Boss, tell you something, a great thing!" Josser's paper has just been reviewed, guess where it went? ”

"Why?"

"What are you kidding? Boss, I just sat next to me and watched the conversation between him and the editor-in-chief! Don't you know how wonderful their conversation is, Professor Duggan also warmly invited José to Princeton in the video, and said that as long as Joser nodded, he could directly enter his research group, study the N-body problem together, and teach Newton a lesson. ”

Walking out of Qiao Ze's office, Liu Chenfeng was completely proud.

"Okay, little boss, I'll definitely try. It's our project that is coming to an end, right? Do you need manpower on your side next? I can do anything, it doesn't matter if I have a subsidy or not. Liu Chenfeng asked eagerly.

"Thank you, little boss. Then I'll go for the questions first. ”

Liu Chenfeng's perception of this world has been completely subverted.

"No, it's not enough, and it's useless for you to call me anything! Only God knows why I made you my student at that time. You are full of the virtues I hate, and you have none of the vices I admire! You're not even as good as an eighteen-year-old!

"Oh, let's go deeper into the next topic, the 2DYang-mills theory proof on Riemann's face. You have to keep doing it if you don't want to waste time, but you have to sacrifice some time to read the previous papers. Qiao Ze nodded.

Hanging up the phone, the little old man's mood finally became a little better.

I didn't see Su Mucheng and Lu Lu's mother going shopping, Qiao Ze's first thought was to ask his big boss to recruit someone to help carry the bag?

When he came to this research group, Xu Dajiang repeatedly explained to him that Qiao Ze had any progress here, and he had to report to him at any time.

I hope you will be ashamed and courageous. You have to know that every math school kid in Princeton is an elite, and we only accept elites, and if you can't even handle this pressure, then you're not a fit here. I advise you to transfer. That's what Kennedy did, and he couldn't graduate here, so he transferred to Harvard. ”

This is not Liu Chenfeng's wishful thinking, but a reference.

One can imagine how eager Liu Chenfeng was at this time.

After all, the green smoke of the ancestral tomb can't keep rising, otherwise it will burn out.

Lott Dugan still remembers that he was very serious at that time looking at Qiao Ze through the video, this child from Huaxia, when he said this, his demeanor was very natural, even very sincere.

So there must still be a chance, and as long as Joser is willing to come, Lott Dugan feels that he will have a third student who can win a Fields Medal.

The only thing that annoyed him was that his current students seemed to be a little less competitive than Qiao Ze.

"No, no."

"Uh...... Not much for now. It's been going well lately. Liu Chenfeng replied a little stiffly.

……

"I'm 100 percent sure that Joser had just finished a video conversation with the editor-in-chief of the Annals of Mathematics, Lotter Dugan. It is the editor-in-chief of the Mathematics Yearbook who personally assesses it, and Qiao Ze is responsible for answering the other party's questions, just like the defense, and after the completion of the editor-in-chief personally said that it will be handed over to the editor in charge for proofreading tomorrow, and he also promised very definitely that it will be published in the October issue. ”

"Okay, Brother Liu, do you have any questions about your graduation thesis?" hung up the video, and Qiao Ze, who was in a good mood, asked.

After the excitement, Liu Chenfeng suddenly remembered that he still had to inform his boss.

And it feels like you're picking wool at school.

He was only eighteen years old and could work on such a powerful subject on his own, and his students, who took time out of his week to answer questions, were still plagued by all kinds of problems, so that some of them were even in the mood to go on vacation. This also made Lotter Dugan think more and more about it while walking.

Although Tan Jingrong did not invest in the top journal of mathematics, the impact factor of "Applied and Computational Mathematics" he voted for has risen rapidly in recent years, and it can be regarded as the top stream in the second area of SCI. What's more, Tan Jingrong is only a graduate student, not yet a doctorate.

"No, dear tutor, we already have a lot of homework......"

It's a pity.

So he probably, maybe, probably really meant it......

This project was also completed too quickly.

And Joze's response also made Lott Dugan feel hopeful.

After all, the publication of Qiao Ze's paper in the "Annals of Mathematics" is a great thing for the school, and it will only be praised.

Although he did not win the award himself, he will be the mentor of the first three Fields Medal winners in history.

Their mentors have just been underestimated, and these children should be ashamed and courageous, and there is nothing wrong with them.

He saw with his own eyes and heard with his own ears Lott Dugan's solicitation of Josser, and then experienced Josser's reverse invitation to the mathematician to take up a teaching position at Xilin Institute of Technology.

Tan Jingrong, who is in the same research group, has stayed in the research group for a long time and is usually silent. But Qiao Zezhen helped the guy open the question, and now the papers have been written, and even the preliminary review has passed, and even the page fee has been paid. Just wait for the editor in charge to review, typeset, and then publish.

If you don't hold such thick thighs tightly, you will suffer retribution in the future.

Liu Chenfeng felt that the old man on the other side could probably only do this step towards his own closed disciples.

"Okay." José answered.

After the other party politely refused, he even talked to Qiao Ze about the process of proofreading, reviewing and finally publishing.

Huaxia, Xilin University of Technology, New Confidential Optical Experiment Building.

Although José didn't need any money, the program had to go.

He also took the initiative to consult Qiao Ze's opinion, whether to go online first or publish the Internet at the same time.

Thinking about it makes the little old man feel very happy.

After thinking about it, he said: "The scientific research fund pool of the college is almost out of money, and if you apply for a new project immediately after the completion of the project, there may not be funds." ”

"No, no, boss, what paper can I say? It's the paper I participated in! Published in the Annals of Mathematics, the Annals of Mathematics in Princeton, Joser gave me three works. ”

"Oh, Professor Dugan, I'm still trying to figure it out. You know, math inspiration can sometimes be like a cat's ......."

The child has not yet opened his mind, and when he sees the world and understands the history of Princeton University, he may yearn for this holy place of mathematics.

After Jozer expressed his indifference, the editor-in-chief even promised to ask the editor in charge to complete the proofreading and finalization as soon as possible, and then publish it in the journal that will be published next month. He also said that he would mail dozens of more photocopies and journal originals to Qiao Ze.

"I don't want to go."

Although he got three of the four great journals of true mathematics as he wished, anyone who encounters this kind of opportunity wants to have more.

In a sense, this also made him even with Qiao Ze.

If you want to take the road of scientific research in college and follow Qiao Ze to improve for two years, graduation will definitely not be a problem, and the starting point after graduation will be a cut higher than other mathematics doctors. Not to mention that this year is the beginning of his third year of Ph.D., and it takes him five years to graduate, which is not a big problem. It took seven years for his brothers and sisters to graduate.

It's just that Qiao Ze obviously hasn't thought about this question yet, and he was rarely stunned by Liu Chenfeng's question.

And it's not a leak either.

Really, at this point in the conversation, Lott Dugan was just a little annoyed, but then Jozer's words opened his eyes.

Well, this is a young mathematician who doesn't know anything about the world.

……

"Hmm." Qiao Ze nodded.

Liu Chenfeng knew how important this news was, and left enough time for the other side to react.

So the little old man couldn't help but take out the phone and dial it out.

After that, when Tan Jingrong chooses to study for a doctorate, he can basically take off directly.

Not to mention that Liu Chenfeng felt that Qiao Ze actually had a good relationship with his big boss.

When I got to the door, the annoyance was at its peak.

This is the Western University of Technology, the School of Mathematics is not an advantageous discipline, and it seems that an alumnus once published an article in this journal in history, but the doctorate is at Yanbei University. As for the faculty members in the school, none of them have published articles in the Big Four so far.

The three works of the Annals of Mathematics are stable!

After all, from the founding of the People's Republic of China to the present, the number of papers that have been reviewed and published in the top four mathematics journals in China does not exceed 30. And whoever has sent a paper and been accepted is or has been a big man.

After listening to Li Jiangao's persuasion, he used a very easy paper to conclude the topic, and the scientific research funds approved by the school were used to purchase servers, pay page fees, and the school would give a bonus after sending the paper. After such a calculation, in just one month, the school will have to pay a price of 800,000 yuan for his semi-finished paper.

"Professor Dugan, I see, I'll do my best to finish all the extra homework you've assigned."

"I don't have a problem, studying for a Ph.D. is the process of learning. It's a big deal that I'll delay it for two years, and it's out of the way. Liu Chenfeng said immediately.

His uncalm expression at the moment is like a 150-pound child.

"No, no, no, Grimm is not prevaricating me with your theory of inspiration. Yes, inspiration is important, but a lot of practice and accumulation is more important for math, so I decided to give you some extra homework and send it to you later, all the exercises you have to complete within a week, and then give it to me. The completion of these exercises will determine whether you will graduate successfully. Of course, not only you, but all those who cannot submit their results within the specified time will be treated the same way, do you understand? ”

For example, if Qiao Ze can give him a proposition, he will complete it independently, and then ask Qiao Ze to help polish the pen, and by the way, help recommend it to the old man in the video just now, even if the corresponding author gives Qiao Ze, he will be a work, and he will be able to walk sideways in the Chinese mathematics community in the future.

It's a good idea to start with a unity study.

After a long time, Xu Dajiang's voice came from the earpiece: "Are you sure?" The journal has already replied? Has the editor in charge started proofreading, or has the review just passed? ”

"Little boss, what do you say? Now the academy is rich! You don't know yet, do you? My director cut off a large amount of money from the international student subsidy, not to mention more, there must be millions of dollars. As long as you apply for the project after you finish the project, he guarantees that the approval will be faster than anyone else! Liu Chenfeng said excitedly.
