To be honest, Qiao Yu felt that old Xue's emotion before leaving was a bit inexplicable. Of course he would come forward! It would just be sooner or later.

And isn’t what he did gay?

The master is a big boss, and the master is also a big boss. Whoever chooses to think about it should have to grasp it with both hands, and both hands must be strong, right?

Books on morality and rule of law all say this, and he is learning and applying it flexibly.

After bidding farewell to Lao Xue, Qiao Yu turned his energy away from these trivial matters and read Peter Schulz's second paper seriously.

On the one hand, this is his interest; on the other hand, Qiao Yu knows very well that he can establish bonds with these math masters because of his mathematical understanding. It would be a pity not to use it. More importantly, although that

Professor Zhang is right, but he still

Not too convinced though.

It was similar to the mood he had when he wanted to solve the problem after being ridiculed by a group of people on the Decimal House Forum.

Although Qiao Yu can be shameless when coaxing others, he has always been extremely proud. Let alone doing mathematical research, even when he was playing games in an Internet cafe, he would not allow anyone to play better than him.

coquettish.

In short, he said he wanted to solve this problem, and he had to solve it beautifully. In addition to his competitive spirit, Qiao Yu had a feeling that his direction was definitely right, but there were still some details that he had not thought through.

.

During this period of time, he will first study the theoretical framework of Peter Schulz's paper thoroughly, then think about this problem, and then solve this problem beautifully, giving Professor Zhang a little Qiao's

Shocking!

By the way, I can also give Teacher Tian and Grandpa Shi a little taste...

Think about it, if Teacher Tian and Grandpa Shi are determined to carry forward the teacher's school in the future, it depends on him, wouldn't this bilateral assistance be stable?

Qiao Yu has long seen that from the good old man to Lao Xue, to Director Tian and Grandpa Shi, the most important thing is his ability to solve problems. Especially when he thinks that in Class 13, he just solved a paper casually.

The finale question can make the guy from Class 13

The math teacher smiled like a child, and he was full of motivation.

If he can make Director Tian laugh like a child together with the master teacher across from him, he can be considered a man of great merit, right?

It was not too late to read the paper in the evening. At half past ten, after reading about half of it, Qiao Yu went to bed. Too late

Professor Robert showed his kindness to him, so he still had to give him face. When he went to attend the lecture tomorrow, he couldn't seem to be in low spirits.

And to be honest, Qiao Yu felt that this professor was quite good.

He had seen many of the mathematical techniques mentioned in the lecture before, but the method used by the other party was very clever, which made Qiao Yu feel fresh and new.

For example, in Grothendieck's point formula, he had also come across and used it online when he was thinking about how to solve the Diophantine equation obtained by Lao Xue.

But Professor Robert's team came up with a new trick. They first constructed effective divisors, analyzed the distribution of zeros and poles, and finally used point formulas to approximate the upper bound of rational points, which was a usage that Qiao Yu had not thought of before.

In short, it is still very useful to listen to this kind of high-level lecture.

Especially yesterday, Professor Robert was very confident and proud of today's lecture. Maybe there are some methods that he can learn from?

Lao Luo is a good man, and his papers on solving problems can cite more of this professor's achievements.

BBASB

There was not much to say the next morning.

It was Lao Xue who accompanied him to attend the lecture. As expected, Director Tian did not come today.

But it was obvious that Professor Robert's lecture today was more passionate, and twenty minutes of free discussion time were reserved.

It was said to be a free discussion, but the professor did not have much communication with other people. He only answered two questions from others at most, and then continued to interact with the close disciple of Academician Tian in the front row. He was not invited to participate in the Q&A session yesterday afternoon. Naturally, the professors and doctors who attended that seminar didn’t know the real reason. They only thought that Tian Yanzhen told Professor Robert something that led to this scene. To be honest, not everyone can get used to it. .

After all, it would be somewhat unpleasant for a big boss’s student to divide resources like this.

Many people even had the idea of ​​watching Qiao Yu's joke, but unfortunately, Qiao Yu caught it and had a back-and-forth discussion with Professor Robert. Well, it can only be said that this kid still has some substance.

After the lecture, Robert chatted with Qiao Yu for a few more words before leaving with satisfaction.

Xue Song planned to take Qiao Yu to the library first, borrow a few books from the instructor's list, read them, and then go directly to dinner.

As a result, as soon as he left the small building and walked in the garden of the research center, Qiao Yu took out his mobile phone and walked slowly behind him. "Don't use your mobile phone while walking. It's both unsafe and annoying."

"I'm not playing with my phone." Qiao Yu raised his head, glanced at Xue Song, and explained: "I was reporting to my tutor and master on WeChat about my experience of listening to Professor Robert's lecture today. I wrote it immediately and sent it to Tian Make a copy, then make a copy with Grandpa Shi, change the title and send it over."

Xue Song was stunned for a moment, then stopped silently and said, "Then just stand there and finish writing your experience with peace of mind."

"Oh, okay!" Qiao Yu agreed, and then stood there editing quickly on his phone. Five minutes later, Qiao Yu raised his head, put his phone back into his pocket, and said to Xue Song, "It's done." "Well, let's go." Xue Song silently took Qiao Yu on the road again, and couldn't help but ask: "Is this the request that Professor Tian asked you to go to the office yesterday?"

"No!"

Qiao Yu shook his head, looked at Xue Song doubtfully and replied: "Does Director Tian still need to ask for this? He specially booked a ticket for me and asked me to come to attend Professor Robert's lecture on the eighth day of the lunar month. He must have hoped that I could It’s rewarding. Director Tian was here yesterday, so I don’t have to report. Today, Director Tian didn’t come, so of course I have to take the initiative to report. It should be quite happy to let the teacher know that his hard work has not been wasted. Right?

Well...Mr.

Xue Song shook his head blankly. It was usually not his request. No one took the initiative to report this to him, and students rarely took the initiative to chat with him. Who would mention this to their supervisor? Of course, doctoral students must decide on the topic or

Except when the paper needs revision.

When he was studying for his PhD at Princeton, he seemed to rarely do such things. On the one hand, he did not feel that learning was a very independent thing, and he never thought of doing so; on the other hand, he felt that his supervisor was also very busy and had nothing to do.

It's best not to disturb me. "Ah? Then how do you get pleasure from teaching students? Don't people want to see rewards after they have put in the effort? Do you think you are just teaching other students to complete the task?" Qiao Yu felt a little uncomfortable.

asked understandingly.

Xue Song pouted and said, "Teachers are usually very busy, especially your tutor. How do you know you won't disturb the tutor?"

Qiao Yu glanced at Xue Song and replied without any psychological burden: "I didn't ask Director Tian to reply to the message immediately? Besides, it's my business whether to report it or not. Whether Director Tian replies to the message is his business!

I'm a student. If Director Tian thinks that I don't need to do this, he will definitely tell me directly. Then can't I just not report it next time?

Besides, Director Tian is not busy all the time. People always need to rest. When they are free, they always check their mobile phones. I only talked about some gains and insights. He thought it was right. In fact, he didn’t need to reply to me. He thought it was wrong.

You can choose a time to give me a call or something.

The most important thing is that when Director Tian gave me the book list yesterday, I said that I would take the initiative to report to him on my week's reading status before every Monday, and he did not object! This shows that Director Tian does not resist my initiative to report my study.

progress, right?"

After listening to Qiao Yu's explanation, Xue Song was silent for a long time, putting himself into Tian Yanzhen's perspective and wondering what it would be like to have such a student. Then he asked again: "Then why do you still want to talk to your master?"

Where’s the report? Your master didn’t find this resource for you, right?”

This question made Qiao Yu a little confused. He looked at Xue Song with strange eyes and asked: "No, Teacher Xue, you are an adult. You should know more about this than me? Grandpa Shi is opposite, and I can't run around every day."

In the past, we had to keep in touch regularly, otherwise the relationship we finally built up would fade away.

Besides, if I don’t talk to Grandpa Shi about this, why should I send a message of greetings every day? Isn’t that just flattering? And reporting my daily gains to Grandpa Master can also enhance his confidence in me, right? The same thing, Grandpa Master

Although he is busy, he does not need to reply to my message!

The most important thing is that the content only needs to be edited once. Sending a message to Grandpa Shi is just a matter of copying it. Just change the name in front of it. It can be done in a few seconds. If you don't do this, you are in trouble, right?"

I don't know why, but after hearing Qiao Yu's explanation, Xue Song suddenly felt like crying.

I remember that his mentor at Princeton was also a great person, but every time he sent an email to his mentor, he had to think for a long time before he could muster up the courage. And every time he wrote an email to his mentor, he had to carefully consider every word. How different from Qiao Yu was so casual and didn't think about anything at all. He compiled an idea in about ten minutes and sent it directly using an instant messaging software like WeChat.

Or the teacher and the master are fighting each other, one document, two gains...

Yes, people have to keep in touch with each other, otherwise the relationship will fade away! After so many years since he graduated, he seems to have rarely sent emails to his former mentor. Occasionally, when he wants to ask for advice, he still hesitates. After thinking about it... Really, Xue Song suddenly felt that compared to Qiao Yu, he looked like a retard!

And this kid is only fifteen years old! When he was fifteen... forget it!

Just when Xue Song felt overwhelmed with sorrow, Qiao Yu took out his mobile phone from his pocket again and said: "Oh, Grandpa Shi has replied to the message... It's over, it's over, Grandpa Master doesn't talk about martial arts. I reported my thoughts to him, and he actually asked me to take the exam by the way. Mr. Xue, please wait for me. I will reply to Grandpa Shi first.

By the way, Teacher Xue, I remember that the Riemann-Roch theorem seems to be able to be used to calculate the dimension of a specific divisor on a curve independently of other tools, right?" Xue Song thought for a while, then nodded.

Then he stared blankly at Qiao Yu standing in the early spring sunshine, editing content on his mobile phone quickly with both hands, and couldn't help but be fascinated. He didn't know whether Qiao Yu was being thick-skinned, or if this was how he should be.

But he always felt that if he had been like this boy and not worried so much, his achievements now would definitely be more than that.

Maybe even if he returns to China and still teaches at Yujiang University, he can still be a member of the large team of former mentors, remotely contribute his ideas and participate in the writing of big papers.

Because after he really got involved, he felt that if one of his doctoral students had a decent talent and often took the initiative to report his learning experience and progress to him, he would probably be willing to give such students more opportunities. Just like this quietly After waiting for another ten minutes, Qiao Yu put the phone back into his pocket again.

Xue Song asked: "Are you done talking?"

"Well, Director Tian just replied and asked me to keep up my good work. In addition, Grandpa Shi said that he will be free after two o'clock this afternoon, so he asked me to bring the book and read it in his office. If there is anything I don't understand, I can Ask him at any time. Hey, Teacher Xue, do you think I have performed too well? It was originally agreed that I would visit Grandpa Shi after Professor Robert went back. But Grandpa Shi said that I would go there this afternoon." Qiao Yu said somewhat worriedly.

"Haha...haha...that's good. Go ahead. Anyway, Director Tian allows you to go there often for advice." Xue Song said numbly.

"Well, so I agreed. In fact, I wanted to postpone it for a few days. I planned to think about the problem first, and then show off to Grandpa Shi after I achieved some small results. I passed by without any preparation, and I felt a little bit better. I'm a little nervous, after all, we only had one phone call..."

Xue Song glanced at Qiao Yu and asked, "Are you still nervous? I think you should consider how to hold it back...for example, don't deliberately omit the first word when calling Master Shi on the spot." Qiao Yu blinked, thought for a while and said: "It has to be you, Teacher Xue. It does make sense. This can bring the relationship closer faster, right?"

Xue Song was so angry: "I'm not giving you advice, I'm reminding you! By the way, did Mr. Yuan specify a list of books to read in the afternoon?" "No, he said any book in the first batch of catalogs would be fine. "

"Oh, then you can borrow the two books you are most interested in." Xue Song nodded and didn't want to say anything. He could read in Mr. Yuan's office and ask questions at any time. Xue Song didn't know how to evaluate this kind of treatment. It was probably Shoot mosquitoes with a cannon?

After all, for basic mathematics teaching books, any professor can explain it clearly to Qiao Yu. Of course, masters are different after all. For example, when explaining a theorem, ordinary professors may just finish it, but masters can often extend it. Published a lot of related stuff.

Of course, a master-level figure would definitely not waste so much time on a single child. Let's put it this way, Xue Song suspected that even Mr. Yuan's grandson would not be able to enjoy this kind of treatment. But what could he say?

Xue Song now even suspected that God sent the child Qiao Yu to him not to teach him, but to learn how to behave.

At only fifteen years old, he was able to coax two top tutors around. When he grows up, becomes more mature, and really has all kinds of resources and abilities in his hands, what the hell will it be like? I'm afraid that in the Chinese mathematics community Can you really turn your hands into clouds and turn your hands into rain? After walking silently for a while, Xue Song suddenly had a whim and asked in a low voice: "Qiao Yu, let me ask you a question."

"Well, in mathematics?" Qiao Yu responded casually.
To be continued...
