When my students proposed this proposition, both of them were in China and were invited to attend a seminar on this proposition. Qiao Yu was the speaker at that time. Even the proposal of geometric constraint invariants was made by Professor Zhang Shuwen there. A request made personally to Qiao Yu at the seminar.

After hearing these words, Lot Dugan probably made his own judgment in his mind.

Well, a student can let a world-renowned mathematician tutor use all his years of business as an academic guarantee. If this student is not the mathematician's biological son or grandson, it is enough to explain many problems.

Lot Dugan didn't even think about appropriating other people's work.

After all, no matter what benefits are promised for such a result, the original author cannot give it away.

"Well, I'm very happy to hear this answer. I will personally serve as the editor of this paper and find suitable reviewers for this paper. If there is a chance, I would like to meet you as a student. Congratulations

, Professor Tian, ​​can find such students.

To be honest, before this, I really didn’t believe that someone could understand Schulz’s paper at the age of sixteen and apply his mathematical methods to his own research. This sounds like a science fiction story.

"

"Thank you, Professor Dugan. In fact, he is indeed extraordinary and has brought me many surprises. Thank you for finding suitable reviewers for him personally. By the way, I also believe you can understand my concerns.

, so the paper has been published on ArXiv. Of course, we have not done any publicity for the time being."

"Okay, I can understand. But... forget it, then it can only be a single-blind review. But it doesn't matter, because I believe your student is not a well-known figure, and no one has heard of him yet.

The name is just the first paper he completed independently, right?"

"You are wrong again, Professor Dugan. In fact, this is the second paper he has completed independently. His first paper was published in the Journal of Number Theory. At the age of fifteen, he summed up a type of three-dimensional

Methods for solving the Phantau equation.

"Well... I'm more interested in your student. If there is a chance, maybe we can let him come to Princeton for exchange." "Of course, but he is still too young. Maybe in two or three years.

Bar?"

"It's a deal. Okay, I won't delay your rest. Professor Tian, ​​I'm glad I could talk to you so much. Goodbye." "Goodbye."

After hanging up the phone, Lot Dugan thought for a moment, then took out his cell phone and called Zhang Shuwen.

It has to be said that Tian Yanzhen's introduction made him more curious about Qiao Yu. He wanted to talk to Zhang Shuwen, who had met Qiao Yu, about this young genius he had never met in person. The call was quickly connected.

"Hey, Professor Zhang, are you free now?

"Not yet. It's Q&A time in my office and it ends in twenty-five minutes."

This is indeed no time. Office hours are also called Office Hours. This is a task that professors teaching at Princeton University must complete every week.

During this period, professors need to stay in the office all the time, waiting for students to come to them to discuss academic issues, course content, research methods and even life directions. Waiting for anything to be discussed and communicated with the professor.

When professors are too busy, it is common for teaching assistants to take their place in classes. The school also allows teaching assistants to take on part of the teaching tasks, especially discussion classes and tutorials. However, OfficeHour professors must stay in the office in person, otherwise they will definitely be complained by students.

After all, Princeton is a private university and the tuition is expensive. If students feel that the professor does not provide them with the help they deserve according to regulations, they will definitely be dissatisfied. "Okay, how about having lunch together?"

"Well, okay, but what's the matter?"

"I want to discuss a person with you. It should be said that he is an extremely talented Chinese mathematics star. "You mean Qiao Yu? How do you know him?"

"Haha, it seems we have reached a consensus, let's talk about it at lunch. How about just at Laurea? I haven't had Italian food in a long time. "Okay, Dean Dugan."

After hanging up the phone, Lot Dugan immediately and enthusiastically began to arrange for Princeton's Supercomputing Center to verify the formula given by Qiao Yu's paper. Although the paper ended with a report issued by the Yanbei University Supercomputing Center, the unit of the paper was also

Wasn’t it written by Yanbei University?

Having this report can save a lot of time for secondary verification. For example, the program does not need to be written again. Just check it once and there is no problem, and then use it directly. After the work was arranged, he sent it to Robert Green.

Got an email.

Then I logged into Princeton's literature system and found Qiao Yu's paper published in the Journal of Number Theory, downloaded and printed it.

This series of actions can probably be understood as the basic review of a new author as the editor in charge of the paper. Everything is based on the rigor of academic papers. As for the second author of the paper, he was directly ignored by Lot Dugan.

The paper clearly states the contribution of the two authors to the paper. To be honest, as an independent researcher and only providing some inspiration to the author of the paper, it is a bit reluctant to be listed as the second author.

But people are always a little tolerant towards unknown young geniuses.

After doing this, Lot Dugan looked at the time, it was almost half past eleven, then picked up the printed paper and prepared to go to the appointment.

Although we don’t have the habit of having a full meal at noon, the Laurea restaurant right in front of the school is still very good, and it is very suitable for an occasional toothpaste. But the most important thing is that although this is an Italian restaurant, it has

French restaurant style - food is served very slowly.

Although this can hardly be called an advantage in many cases, it is different when we need to talk about things.

And there are fewer people at noon, so no reservation is needed.

···

When Lot Dugan came to the restaurant, Zhang Shuwen had already arrived first.

After saying hello, the two of them sat at the dining table. Lott Dugan didn't say any more nonsense and directly handed the paper to Zhang Shuwen: "After reading this paper, you will understand why I want to talk to you about Qiao Yu, right?"

For me, this is a rare surprise in recent years.

To be honest, even if Professor Tian is willing to vouch for this child’s academic work, I still find it hard to believe that this is a thesis completed independently by a sixteen-year-old child.”

Zhang Shuwen took the paper handed over by Lot Dugan, glanced at it, and said in surprise: "He actually came up with this proposition? How long has it been since?"

"Yes, not only was it done, but the conclusion was perfect. It seems that you have indeed participated in his seminar. I suddenly want to know when he determined the proposition, but I still recommend that you read the introduction first.

Partly, I am willing to keep this expectation for a while."

Lot Dugan said expectantly.

Zhang Shuwen glanced at Lot Dugan, and then continued to read.

Obviously, after seeing the general formula, Zhang Shuwen once again showed a surprised expression. Then just like Dugen thought, the professor quickly began to browse according to the table of contents, skipping most of the previous proofs and turning directly to

About the proof process of geometric constraint invariants, and start reading more carefully.

Until the waiter brought the Italian barbecue ordered by the two of them, Professor Zhang was still indifferent to the food. Lott Dugan did not disturb the other party, but he picked up the knife and fork and ate with relish.

.

Fortunately, Zhang Shuwen still remembered that this was in a restaurant, so he did not read it in depth. He just skimmed it quickly and carefully read the verification report given by the Supercomputing Center of Yanbei University at the end of the paper, then put the paper aside.

Yes, he didn't give it back to Lot Dugan.

"There is no need for this. Professor Tian has already published the paper on ArXiv first." Lott Dugan looked at the paper and said.

Zhang Shuwen replied directly: "I can't believe that Qiao Yuzhen can achieve this level in such a short time, so I hope to be one of the reviewers. Please rest assured that I will review it carefully with the strictest attitude."

This article."

Lot Dugan was stunned. It was obvious that he only wanted to talk to Zhang Shuwen about Qiao Yu today, and did not invite the professor to be a reviewer. However, regarding this kind of initiative...

"Well, you know, Professor Zhang, I do plan to invite some Chinese scholars to review this paper. If you insist, why not? I have already asked people to use TIGER to verify the results. If the final results are consistent with the paper

If the report is consistent, you will be one of the reviewers.

So now it's time for you to satisfy the strong curiosity of a paper editor. Professor Tian said, not only did you participate in that seminar, but even such a concise result of this paper was your request? Is that true? That time

When was the seminar held?"

Lot Dugan shrugged, gave his own answer, and asked his own question.

"Yes. I was invited to attend that seminar when I went to Huaqing this year...

As soon as Zhang Shuwen started to explain, he was interrupted by Lot Dugan: "Wait, this year? I remember you just went to China and it hasn't been a few days since you came back."

"Yes, if I remember correctly, the seminar was on February 7th, which is of course Chinese time, which is the early morning of February 6th here." Zhang Shuwen said with certainty. There is no way, the memory of that day is too

Too profound.

"Wait, February 7th? Today is February 23rd. If I remember correctly, when I talked to Professor Tian today, what you discussed on February 7th was a feasibility report on this proposition? That is He said that from the time he decided to do this project to the completion, um... it only took half a month?"

Lot Dugan asked in surprise.

Zhang Shuwen nodded, and looked at the dean of the college across from him holding a knife and fork, raising his head in surprise, and felt a little happy. After all, Qiao Yu is a Chinese, and he is still a young Chinese who has not received systematic Western education. people.

"Yes, Professor Dugan. This is also the reason why I hope to be a reviewer of this paper. To be honest, I was surprised to see his results, because his ideas were still very immature at that time. I gave him a suggestion.

It means leaving all the complicated things in the proof process, and the result must be simple to be a truly useful mathematical theorem. If the result of the paper is correct, it means that he not only listened, but also did it."

Zhang Shuwen replied calmly.

"Well, I'm more interested in this story. Your barbecue is almost cold. You can talk while you eat it. I'm very interested in knowing what happened that day."

This lunch, which was too rich for Westerners, took about two hours to eat.

Leaving aside the time that Zhang Shuwen focused on the paper, he spent about half of the time talking about Qiao Yu. But this was enough to make Qiao Yu's image three-dimensional and full in Lot Dugan's mind. Plus some Filter..

This is a humble and well-behaved genius.

He has not yet received a relatively complete mathematical education. Most of his mathematical knowledge comes from self-study. Even before he had this idea, he did not know the basic tool of the Riemann-Roch theorem.

Even without any guidance, I can read Schulz's paper.

Of course, the latter is only the news that Zhang Shuwen heard and cannot be proven for the time being. But even if someone tutors it, it is already shocking enough.

After lunch, Zhang Shuwen asked: "Professor Dugan, I would like to ask, if the supercomputer review proves the correctness of the formula, which experts do you plan to invite to be the reviewers of this paper?"

Lott Dugan smiled and replied: "Obviously, Schulz is a good candidate. I think if he knew that there was a child with the same talent as him and extended his theory, he would You will definitely be very interested."

Zhang Shuwen asked: "What else?"

Lot Dugan said in a consulting tone: "What do you think of Dennis from Harvard University?"
