Chapter 123: The other side must have given too much!

At 7:58 the next morning, Pan Jingyuan was already sitting in front of his computer, logging into Zoom through the invitation link sent by Professor Dennis in the email. Because the team members were distributed in different regions, even across three continents, he had already gotten used to using Zoom for meetings.

As one of the official platforms cooperating with Harvard, Pan Jingyuan was already accustomed to using this conference system when he was studying for his doctorate at Harvard.

He was the sixth person to enter the conference room, and through the video he could tell that everyone was in a low mood.

In fact, the same is true for Pan Jingyuan.

Although he had accepted this fact, he was still not very happy.

On the other hand, the convener of the meeting - his mentor Dennis looked calm.

About a minute later, Professor Sam entered the conference room on time, and everyone was there.

"Okay, everyone should know the situation now. Pan, you have had a face-to-face communication with Qiao Yu in Huaqing, so please tell me what you think first." When everyone was present, Dennis started calling the roll without saying anything polite.

Of course, in this kind of small meeting like a group meeting, everyone is familiar with each other and there is really no need to say any polite words.

Pan Jingyuan quickly gave a brief summary of what was discussed at the meeting last night.

Most of them are the opinions of other professors. As for himself... to be honest, he doesn't have any ideas.

There was no point in saying more unless he could solve the problem right away, but it was clear that he had no idea yet.

He couldn't tell everyone that he had been tutoring Qiao Yu and answering all of Qiao Yu's questions during this period, right? His tutor wouldn't blame him, but others would probably want to eat him alive.

From the expressions of several people, it can be seen that not everyone can calmly accept the sudden complications at this time.

"Okay, thank you Pan. I believe everyone has seen Qiao Yu's proof. To be honest, I think it is very beautiful. Obviously, we underestimated the complexity of this problem. But I hope everyone can cheer up and solve problems when they arise.

Complaining about anything else now is useless, so I hope everyone can focus on solving this problem thoroughly. Sam, where do you think we should start to solve this problem? Of course, others can speak up if they have ideas..."

……

The video conference lasted more than two hours.

Although everyone was in a low mood at first, Dennis was very good at motivating people.

For example, during meetings, he never let people choose whether to speak or not, but called on everyone one by one. Those who were called on would say a few words, regardless of whether they had an idea or not.

At least Pan Jingyuan feels that this way of meeting is more efficient and more useful.

People's thinking is naturally lazy. When they are free to speak, they often put their hopes on others and are too lazy to use their brains. However, calling on everyone one by one forces everyone to think and then say something.

During this process, you may get some inspiration, or even some perfunctory speeches may bring inspiration to others.

But the effect today was not very good.

Although many methods were proposed in the next hour, Pan Jingyuan was very clear that these methods would require a lot of time to verify.

Of course, it was normal for everyone who was about to open the champagne to have a brief period of confusion when faced with a new problem. At least Pan Jingyuan believed that under Dennis's leadership, they would be able to finally solve the problem raised by Qiao Yu in one or two months at the least, or one or two years at the most.

The time span is a bit long, but sometimes mathematics is really similar to those chemistry and materials science around it, it depends a lot on luck. Or maybe scientific research also has a certain element of metaphysics in it.

Many scientific breakthroughs that have influenced the development of the world came from accidents or sudden flashes of inspiration.

The former mostly appears in applications, while the latter is applicable to mathematics.

The most famous discovery is probably penicillin. Alexander Fleming originally just wanted to culture some bacteria, but improper operation caused the culture dish to be contaminated by mold. Then he found through observation that all the bacteria around the mold were killed. Thus, the first antibiotic in human history was discovered, and the antibiotic era began in the medical field.

You have to know that when penicillin was first discovered, it was like a panacea described in fantasy novels. The mortality rate of bacterial pneumonia and wound infections, which used to be extremely high, has been reduced since the advent of this antibiotic.

The same is true for mathematics. Maybe you can solve a difficult problem just by a flash of inspiration after waking up from a nap. Of course, there may be no real examples, because such things are very idealistic and mostly come from the oral statements of genius mathematicians themselves. It is difficult for outsiders to tell whether they are bragging or not.

For example, Pan Jingyuan has not enjoyed sudden inspiration or enlightenment, because every time he breaks through, he studies down to earth and then discovers it naturally. But he believes this because he has seen it with his own eyes.

And when a kid next to him suddenly shouted "Got it", and then was invited to the podium to give a speech, he became convinced that this kind of mathematical epiphany was inevitable.

……

As the meeting was about to end, Pan Jingyuan suddenly received a private message.

Yes, Zoom also supports private chat in video conferences, of course, this also depends on the chat permissions set by the conference host. However, as the convener of the meeting, Dennis never restricts the team's private chat function. It is convenient for everyone to communicate privately.

The message was from Frank.

To be honest, Pan Jingyuan's personal relationship with Professor Frank was very ordinary, and they did not have much communication on weekdays. It was the first time in his memory that the other party specifically sought him out for a private chat during a meeting.

Although they were the only two people from China in the team, the other members of the team thought that the relationship between the two should be very good. But the relationship between the two was obviously not as good as everyone imagined. Sometimes Pan Jingyuan even felt strange, why he was not so fond of Professor Frank.

In the end, it can probably only be concluded that the friendship between gentlemen is as pure as water.

"Professor Pan, I sent you an email this morning. You might have already gone to bed by then. I mainly wanted to ask you about Qiao Yu's situation."

"Well, what do you want to know?"

"How about Professor Pan, you check your email first, and I'll call you after the meeting. Is that convenient for you?"

"can."

……

Pan Jingyuan didn't think much about it.

A video conference is also a conference. If you chat privately during a conference, you may miss other people's speeches. But now it's basically garbage time. Everyone has basically said what they need to say, and now it's Dennis who is cheering everyone up.

To be honest, Pan Jingyuan has always felt that his mentor is good in every way, except that he is a little long-winded, talkative, and a big loudmouth.

So the last ten minutes or so of every meeting were garbage time, but given Dennis's authority in this field, no one pointed out this little problem.

After all, no one is perfect.

But in the last few days, no one really listened to the mentor's words of encouragement. To be honest, we are all adults and we naturally know what to do next. Besides, mathematical research has its own particularity.

Pan Jingyuan opened his mailbox, found Professor Frank's email in the unread emails, and clicked on it to take a look.

There was nothing particularly noteworthy, mainly asking about Qiao Yu's situation. What made Pan Jingyuan speechless was that this guy actually asked Qiao Yu if he had heard of him and whether he was willing to study abroad in Berkeley.

Fortunately, I only sent him a private email. If Mr. Yuan knew about this, he would probably scold him in the face.

Who wouldn't want a student like Qiao Yu? There's no need to even bother with him. Just leave him there to grow naturally and his future achievements will be limitless.

When Tian Yanzhen was the CMO, he directly tricked Qiao Yu into Yanbei University, which made Mr. Yuan depressed for a long time. This guy wanted Qiao Yu to go to Berkeley to be his student, which was pure dreaming.

Of course, these words were just thoughts in my head. I closed the email and Dennis's speech was almost over.

"By the way, I spoke to Professor Schultz on the phone. He said that he has already made a suggestion to the organizing committee of the International Algebraic Geometry Conference to be held next month. He will invite Qiao Yu to attend the conference and give a 30-minute report. So if you have time, I suggest you attend the conference.

Maybe we can communicate with Qiao Yu. As the person who found the loophole, maybe he will have some special ideas that can inspire us. Of course, Pan, you have the most contact with Qiao Yu. If you have the opportunity, you can discuss more with him. "

"Okay, Professor Dennis." Pan Jingyuan took a deep breath and answered.

Wow, Qiao Yu can give a 30-minute report at the International Conference on Algebraic Geometry?
It turns out that the mathematical world is always so kind to geniuses!

Damn...I'm so envious!

"Okay, that's all for today. If you have any ideas, feel free to email me."

After that, Dennis pressed the button to end the meeting.

As soon as Pan Jingyuan exited Zoom, a long-distance call came in.

"Hello, Professor Frank."

"Hello, Professor Pan, have you read my email?"

"I just read it. But I also asked around, and Qiao Yu doesn't seem to have any plans to study abroad. In fact, he hasn't even started his undergraduate studies yet. As far as I know, the current training method at Yanbei University is mainly to let him study on his own."

"Self-taught?"

"Yes. He has not been assigned any specific study tasks. He has a high degree of freedom in his studies and can choose any course he likes. As for whether he will choose to study abroad in the future, that is a matter for the future. But I guess Yanbei University will not recommend him to go abroad until he reaches adulthood."

"Oh, that's a shame. But since we didn't assign him any specific tasks, why did he suddenly become interested in our research topic?"

Pan Jingyuan also felt overwhelmed when he heard this question. After thinking for a while, he said, "I guess Mr. Yuan mentioned this to him once before. I think you have also read his paper on estimating the upper bound of rational points on curves.

Professor Yuan may have thought that Qiao Yu was interested in the Langlands conjecture, and I happened to be in the team, so I asked him if he was interested in joining our research group. He refused, but perhaps because of Professor Yuan's recommendation, he became interested in our results. "

"I see. Professor Yuan really, really...did a good thing. Otherwise, if the paper was published and proved to be wrong, it would be even more troublesome."

Pan Jingyuan could tell that there was something insincere in his words, so he decisively changed the subject: "Will you go to the algebraic geometry conference next month?"

"I can't be sure yet. It depends on the schedule. By the way, is Qiao Yu still going to participate in this year's IMO?"

"Yes, in fact, he also knows that participating in IMO is meaningless, but he still wants to get a place to repay his alma mater."

"I see. You are a good kid who is grateful."

"Who said it wasn't? Professor Frank, I'll hang up now if there's nothing else."

"Ok."

Pan Jingyuan hung up the phone and shook his head. He always felt that the Berkeley professor was a little absent-minded when chatting.

Never mind. He was too lazy to think about it.

Qiao Yu’s special performance is in the afternoon, and he also wants to go and listen to how this guy plans to whip the corpse.

For Pan Jingyuan, these two days were really tormenting. It was fine that his six years of work had been exposed, but the most infuriating thing was that he was the one who introduced this guy to the field. Just thinking about it made him feel very aggrieved.

……

On Tuesday, April 8, 2025, at 1:50 p.m., Qiao Yu was answering the phone in her dormitory at the International Mathematics Center of Yanbei University.

"I'm in the room, yes, I'm just about to go over...ah? You're coming over...wait, are you going this afternoon too?...No, of course...then I'll wait for you."

After hanging up the phone, Qiao Yu was stunned for a long time.

If he heard correctly just now, Director Tian said that he would accompany him to Huaqing to attend his lecture today?
To be honest, this incident really surprised Qiao Yu.

After knowing that Qiao Yu had contacted the other side, Chen Zhuoyang once told him that although the tutor also had a good relationship with some professors of Huaqing School of Mathematics, he had not taken the initiative to go to Huaqing for more than ten years, let alone attend a lecture with the master from the other side.

It's probably the kind of attitude that I know you are right in front of me, but I choose to keep my distance.

This actually made Qiao Yu a little worried.

He was afraid that Director Tian and his master would really fight at the afternoon lecture.

To be fair, no matter what conflicts there were between Tian Yanzhen and Yuan Zhengxin, at least both of them were very good to him. If they really started to quarrel, he wouldn't even want to watch the fun...

In fact, Qiao Yu still hopes that their relationship can maintain the kind of ambiguity where they occasionally make a phone call, and it is better not to meet in person.

But the mentor's free will naturally could not be interfered with by him.

He didn't have time to think too much. In less than five minutes, Qiao Yu saw Tian Yanzhen waving at him through the window, and he hurried out the door with his computer on his back.

"Director Tian, ​​you really went there."

"What? I can't go over?"

"That's not true!"

"You even call me grandpa, what should I be afraid of? Right?" Tian Yanzhen glanced at Qiao Yu meaningfully.

Qiao Yu was speechless.

Just go, as long as he is not embarrassed, it is others who will be embarrassed.

"By the way, don't use those messy email addresses in the future. For external contacts, just use the email address provided by the research center. I've already applied for you. Professor Xue should have sent the address to your WeChat."

Qiao Yu immediately took out his cell phone and took a look. Sure enough, Lao Xue had sent him a WeChat message.

"address:[email protected], initial password: xxxxxx, home page background:
“What is a home page?”

Tian Yanzhen explained: "You can edit your achievements and put them on the page to show them to the public. For example, your study experience, representative achievements, and current projects. There are templates, and you can understand them at a glance."

Qiao Yu said, "I understand this. I have studied the professors in those centers before. But I am still a student, right? Can students also have a homepage?"

Tian Yanzhen replied: "I've opened a special column for you. You'll know when you log on to the official website."

Qiao Yu nodded honestly and responded, "Thank you, Director Tian. Doesn't that mean I'm very proud of you?"

Tian Yanzhen smiled, and then said, "Yes, you are indeed very popular now. From the 19th to the 23rd of next month, the World Algebraic Geometry Conference will be held at the French Institute of Advanced Scientific Studies. The organizing committee has listed you as a special lecture guest and invited you to give a 30-minute report. How about it? Are you interested?"

"A 30-minute report? In the main venue or the branch venue? What will it mainly talk about?" Qiao Yu asked with great interest.

At this moment, he thought of the senior from Huaqing. According to Lao Xue, that guy was invited to attend the top computer conference in his freshman year. Now he is not even a freshman yet, and someone has invited him to attend the conference, which means he has won again.

Tian Yanzhen glanced at Qiao Yu and said unhappily, "What are you thinking about? You are most likely at the branch venue. As for what to talk about, that's your business. What you can talk about now is about Qiao's point and the derivation of the upper bound of rational number points on the curve. If you decide to go, you can talk about both.

However, the most important significance of this kind of conference is not the 30-minute lecture on the stage, but the opportunity to communicate face-to-face with mathematicians from all over the world after the conference. For example, Peter Schultz, it was he who recommended you to give a report this time. "

Qiao Yu's eyes lit up and he said happily, "Wow! This is the real-life version of asking heroes who is the hero! It turns out that geniuses also admire each other. If I go, won't I have the opportunity to drink with Peter Schultz and talk about heroes? Director Tian, ​​I will definitely mention your name first when the time comes."

Tian Yanzhen paused and glared at Qiao Yu, but his look really had no killing power.

Well, it's normal for a sixteen-year-old to have some messy thoughts in his mind.

And every time he flatters someone, he does it just right, which is really embarrassing.

"So you agree to go?" Tian Yanzhen asked.

"Yeah." Qiao Yu nodded.

He was still very interested in talking to Peter Schultz.

If he were to name one person whom he admires the most after reading so many papers, it would probably be this mathematician.

He used other people's achievements, but they really developed this thing, so the difficulty is very different.

Of course, Qiao Yu didn't think he was inferior to Peter Schultz.

After all, he had only worked out the prototype of the quasi-complete theory during his master's degree. Qiao Yu felt that when he started studying for a master's degree, he might not be worse than Peter Schultz. And he would definitely be richer than this big shot in the future. The latter was very important.

Tian Yanzhen said: "Okay, hurry up and get your visa. Has your passport been processed?"

Qiao Yu replied: "It was done when I decided to participate in IMO. But it was handed over to Professor Zhou for safekeeping."

Tian Yanzhen nodded and said, "We will apply for visas to Australia for you all. Let Professor Zhou help you apply for a French C visa. Professor Zhou will help you make an appointment, and he will accompany you to the embassy to handle it when the time comes."

"Okay, Director Tian. Wait, Director Tian, ​​aren't you going to France to attend this meeting? I have to make a 30-minute speech!" Qiao Yu suddenly reacted and asked.

Tian Yanzhen really glared at Qiao Yu this time: "I will go, but I don't need a visa. I have a multiple-entry visa for Europe, and it hasn't expired yet."

"Oh, I see!" Qiao Yu nodded.

No wonder those awesome people can travel around so often. They can be in the country at night and run to a square in the west to feed pigeons the next morning, as if they don’t need a visa to go abroad... Multiple-entry visas still sound very cool.

However, Qiao Yu still felt that this was a bit troublesome.

I really hope that when he grows up, every Chinese person can buy a ticket and go wherever they want to go. As for visas... we have DF Express, and it's so troublesome to get a visa. It's really annoying just to think about it.

Of course, if foreigners want to come to China, they still need to apply for a visa.

There is no way, there are too many Chinese people...

Anyway, Qiao Yu felt that the facts had taught China more than once that as a country in the global village, it should not be too hypocritical. It was enough to make a distinction between the double standards of the kingly way and the double standards of the hegemonic way.

"You're going to France next month and Australia in July. Your schedule is really tight." Tian Yanzhen sighed.

Every time he thought about Qiao Yu being only sixteen years old, he would sigh and feel a little lost. Maybe it's like this when people get older...

Excellent old people can always see the vigor and vitality of their own youth in equally excellent young people.

This is probably one of the reasons why Qiao Yu is so rare.

……

The teacher and the student chatted casually as they walked, and before they knew it they had entered the territory of Huaqing.

Qiao Yu was planning to go to the Mathematics Research Center as usual, but Tian Yanzhen stopped him and said, "Don't go this way. Go to the library."

"Library?" Qiao Yu was a little confused.

"Yes, your special lecture this afternoon is scheduled in the Century Auditorium of the Yifu Hall." Tian Yanzhen said concisely.

"Ah? Why?" Qiao Yu couldn't help but ask.

"Because the Century Auditorium can normally accommodate eighty people. If necessary, more seats can be added." Tian Yanzhen explained casually.

Oh, the place is bigger.

But Qiao Yu found it more and more interesting.

His special lecture was moved to a new lecture hall, but Huaqing did not inform him, but informed Director Tian first. Qiao Yu was sure that it was not Master Yuan who informed Yanbei, and given Master Yuan's personality, he would definitely not do that.

Well, it has nothing to do with him anyway.

He is only responsible for speaking on the stage; it is none of his business what the audience thinks.

……

He thought so in his heart, but when he came to this lecture hall, Qiao Yu still felt something was different.

Obviously, Tian Yan's real appearance surprised many professors.

But soon Tian Yanzhen took him to chat enthusiastically with the professors invited from abroad, which made Qiao Yu quite embarrassed. Because the foreign professor was really not reserved when praising people...

Especially Professor Elton, who used three "very"s followed by "Good" to evaluate his ideas and achievements, which not only made him feel a little overrated, but also showed the poverty of spoken English vocabulary.

In fact, Qiao Yu didn't mind if Professor Elton changed some of his words instead of using such colloquial language.

For example, excellent, outstanding or remarkable, after all, these words appear more formal.

However, Qiao Yu also keenly noticed that most of the professors from Huaqing just came to say hello and did not gather around them, keeping a rather reserved distance.

Moreover, when these professors saw Tian Yanzhen also appear in the lecture hall, they were obviously surprised, and some were even stunned...

Qiao Yu just found it more and more interesting.

Finally, after a brief exchange of greetings, Qiao Yu was the first to see his master's grandfather walk into the venue.

Really, at that moment, Qiao Yu clearly felt that the noise in the lecture hall had become a little quieter. Director Tian and he were standing facing the door, and across from them were several foreign professors and professors from Yanbei University.

Through the gaps between people, Qiao Yu felt that Yuan Lao should be able to see the instructor. But even if he didn't see him, it didn't matter, because Yuan Lao and Professor Phyllis beside him walked straight towards this side.

Qiao Yu glanced at the instructor beside him quietly, and found that Tian Yanzhen's expression did not change. He rolled his eyes and went straight to meet him...

"Grandpa Master, you are finally here. Director Tian also came to listen to my special lecture today. I am so happy."

Old Yuan smiled and patted Qiao Yu on the shoulder, then walked to the front row where several people were chatting and glanced at Tian Yanzhen.

"Mr. Yuan." Tian Yanzhen nodded slightly.

"Yeah." Yuan Zhengxin nodded slightly, exchanged a few words with everyone, and then said indifferently: "It's almost time, let's get started. Qiao Yu, come..."

Standing on the podium with Yuan Zhengxin, Qiao Yu realized that the more than 80 seats in the lecture hall had been filled up without him noticing, and some people even moved a stool to sit in the back.

But the atmosphere of today's lecture was obviously weird.

Many eyes were still looking towards Tian Yanzhen's seat in the front row, and some were even whispering, probably still unable to accept that Mr. Tian across from them was sitting in the front row of the press conference, face to face with Mr. Yuan.

But no matter what, today's occasion is a perfect stage for a sixteen-year-old boy like Qiao Yu.

Qiao Yu even felt that if the World Algebraic Geometry Congress next month was held at a branch venue, it would probably be on this scale.

The next moment, Yuan Lao's steady voice sounded in the lecture hall.

"Thank you all for coming to today's lecture. Qiao Yu, I believe everyone has already known him. He is a rising star in the mathematics world and a student jointly trained by the Yanbei International Mathematics Research Center and our Huaqing Mathematical Sciences Research Center.

Today, he will share with you his way of thinking about a type of conjugate ridge singular points on algebraic varieties. I believe his lecture can bring us some new perspectives and thoughts, and can also inspire us to have an in-depth discussion in this field. Let us look forward to today's wonderful sharing together. "

Applause began to break out from the audience.

Qiao Yu's mind was spinning with what Yuan Zhengxin had just said...

My goodness, he suddenly became a talent jointly trained by both sides? How come he didn't know about it?

Qiao Yu glanced at Old Tian in the audience... Well, he was fine, still sitting as steady as a rock, clapping with a relaxed smile on his face, not looking very annoyed. It was indeed the demeanor of a big boss, who had discussed it privately and then came over with him in a swagger.

He didn't even let him know a single word, his mouth was so tight-lipped.

Of course, this doesn’t really matter to Qiao Yu…

Anyway, he often came to Huaqing to eat and used the office in Qiuzhai as a study room. If they were to be jointly trained, he thought Huaqing should also prepare a special study room for him, so that he wouldn't have to share a room with Mr. Yuan.

This way he can stay in Huaqing on Monday, Wednesday and Friday, and go back to Yanbei on Tuesday, Thursday and Saturday...

He shifted his gaze from Director Tian to the back row, and was greeted by the stunned looks of the professors in the back row. Qiao Yu found it even more interesting.

But there were some things that made him depressed, for example, not everyone was looking at him, and some people even lowered their heads and did not know what they were doing... Bad review! He is a professor, but he still doesn't pay attention in class. It's so unethical.

Forget it, that’s okay.

Since the big guys in the audience are having so much fun, no one should mind if he jokes a little, right?

Before starting his lecture, Qiao Yu glanced at Professor Pan in the audience again. When the applause died down, Qiao Yu began his lecture.

"Good afternoon, teachers..."

After saying a few simple polite words, Qiao Yu began to explain his entire thinking process in an orderly manner with the help of the prepared PPT.

Of course, during the explanation, Qiao Yu did not forget to sincerely thank Professor Pan Jingyuan for his selfless help.

Pan Jingyuan also received a lot of curious looks.

However, Qiao Yu keenly felt that Professor Pan did not seem to be very interested in his thanks, so Qiao Yu thanked him several more times...

It wasn't intentional. Many of his ideas in the initial stage did come from Pan Jingyuan's guidance, as evidenced by their WeChat chat records.

Of course, Qiao Yu also thanked Professor Elton for inspiring him that day.

This old professor from the Institute for Advanced Study at Princeton smiled sincerely in the audience.

Just like that, forty-five minutes passed quickly.

As requested before, Qiao Yu left fifteen minutes for questions.

After answering a few questions, the lecture is coming to an end.

Qiao Yu began to make a final summary: "Thank you again for coming to today's special lecture. In addition, I have another wonderful idea. Perhaps we can use a new tool to solve the applicability of the local-global consistency problem of the geometric Langlands conjecture on complex singular points.

I even think that this tool may not be complicated. It only needs to allow us to locally reconstruct the geometric structure at this type of singular point and ensure that the local properties can be correctly globalized, so that the Ambidexterity Theorem can still be applied at complex singular points.

For example, we can construct a homology layer in the local geometry of the point and construct an operator that can operate on it in some way. Of course, this is just an irresponsible assumption.

Unfortunately, today's time has come to an end. I think maybe next time we meet, we will be able to discuss a result. And I believe that it must be a good result. This tool must exist, but it is still in the making. Thank you everyone! "

After saying this, Qiao Yu bowed slightly, but the enthusiastic applause that should have come from the audience did not come, and the few scattered applause also disappeared after Pan Jingyuan opened his mouth.

"Qiao Yu, can you tell me your solution?"

Qiao Yu simply shook his head and said, "I'm sorry, Professor Pan, at this stage it's really just an empty idea. I've said everything I can. You know, it's a pure mathematical intuition...

Just like when I studied your team's paper, I had an intuitive feeling that the proof process might not cover all situations. Then I thought about it for a long time, and then I suddenly got inspiration under the inspiration of Professor Elton. "

Then Qiao Yu promised earnestly: "Of course, if I really have a solution, I will report it to you as soon as possible."

……

Finally, warm applause broke out.

Qiao Yu roughly understood everything that happened next, which meant that all the communication would take place after the meeting.

In fact, he had experienced this last time, but he chose to leave quickly and did not stay to discuss it in detail with the professors. But today was different. He and Tian Yanzhen stayed together to join the discussion of many professors, and even had a meal with several invited foreign professors and Huaqing professors from Yuan Lao's side.

Qiao Yu finally had the opportunity to have more in-depth exchanges with these great professors in the field of mathematics.

The questions asked during the lectures were very different from those in the lectures. After the meeting, everyone asked questions and answered them in a very casual and divergent way. For example, during the conversation, some people would comment and analyze some of the ideas and opinions recently proposed by a professor, some of which were approved and some were disdainful.

You can tell the relationship between someone and someone else from some small details.

At the same time, we will also discuss some problems encountered in recent research work. Of course, we don’t necessarily need others to give us answers, but we just want to chat together and see if we can come up with some constructive suggestions.

As we chat about this, we will turn to the research results of a professor who is not present, and the cycle will continue...

In short, this kind of communication is easier and covers a wider range. If you happen to come across a topic that interests you, you can indeed get a lot of inspiration. For Qiao Yu, the biggest gain was probably that in just over an hour, Qiao Yu's brain was filled with the names of several professors he had never met before, as well as their recent projects and achievements.

From this we can see that these mathematicians communicate a lot in private. Although the professors were not present, many of them seemed to be well aware of the progress of their work, including Peter Schultz.

For example, he learned from Professor Elton that Peter Schultz was recently working with Kevin Buzzard, a computer scientist at Microsoft Research, on a "liquid tensor experiment." It was a new term, but after the professors' explanation, Qiao Yu roughly understood that it was to verify the correctness of mathematical theories through computer-assisted formalization.

To be more specific, Buzzard's team developed an interactive theorem proving assistant called Lean and invited Peter Schultz to collaborate. The specific task was to convert complex mathematical theories into a form that can be verified by Lean.

This involves a careful decomposition of multiple mathematical theorems and propositions, and ensuring that each step is accurate in the formalization process.

Qiao Yu felt that this was a thankless job, after all, it sounded like this job would take up a lot of time and energy. However, considering that the partner was Microsoft, Qiao Yu felt that it was understandable...

Microsoft must have given too much!
In addition, Qiao Yu even heard these professors talk about many secrets of the mathematical world, but of course he didn't know whether they could be considered secrets or not.

For example, some of the little quirks of a certain big boss...

Some people even asked him privately about Director Tian and Mr. Yuan, but Qiao Yu just laughed it off and avoided the question...

What does he know about the affairs between the big guys? He knows nothing!

In short, Qiao Yu always sticks to academic issues and boldly expresses his opinions. As for some news in the mathematics world, he just listens to it as a story and never makes any comments...

In addition to communicating with the professors, he was also busy observing the interaction between Huaqing professors and Director Tian.

At first, some people tried to talk to Director Tian for a few words, and after finding that Mr. Yuan did not seem to be obviously unhappy, more and more people began to communicate with Director Tian...

Fortunately, there was no direct communication between Director Tian and Mr. Yuan. When their eyes occasionally met, they would quickly look away, which also made Qiao Yu feel relieved.

Although he thought he had always been honest with the two bosses, as someone who liked to play both sides, he still didn't want the two bosses to sit together and check the accounts when they had nothing to do. After all, no matter how smart a brain is, it is impossible to pay attention to every detail at all times.

It's good to keep a close but distant attitude like this.

The two research centers of Huaqing and Yanbei should cooperate and communicate more in the future. It would be better for the two big guys to stay in their respective territories.

As Qiao Yu was quickly thinking about various ideas in his mind, he forgot one thing: in the Internet age, everyone is part of the network, and professors are no exception.

Just now he was busy looking at the expressions of the Huaqing professors. God knows how many professors were there, and they secretly took out their cell phones to take a picture of Yuan Zhengxin and Tian Yanzhen in the same frame.

Yes, it’s not just professors from Huaqing who do this, professors from Yanbei do the same.

After all, for the Chinese mathematics community, this is definitely a big deal, a huge deal.

Originally everyone thought that these two big guys would never see each other again in this life, but who would have thought that Tian Yanzhen suddenly appeared in the Century Auditorium of Huaqing Yifu Hall and stood face to face with Yuan Zhengxin.

Qiao Yu just thought it was interesting, but to others it was a big melon, a shocking melon in the mathematics world.

So we really can't blame many professors in the back row for lowering their heads and doing little things when his special lecture began. In fact, everyone was spreading the news through their own channels.

Of course, in all those photos that are in the same frame, no matter from which angle, as long as there is the front face of Tian Yanzhen and Yuan Zhengxin, there must be the front face of Qiao Yu.

Because he stood with Tian Yanzhen before, and then stood with Yuan Zhengxin.

During the meal, he simply sat between the two of them, maximizing his exposure.
