.

Then Qiao Yu clicked on Qiao Xi's dialog box on the WeChat interface and sent a video.

Now he is very arrogant and needs someone to pour some cold water on him. There is no doubt that Qiao Xi is the best choice. Because if it were any other person, Qiao Yu would not hesitate to hold a grudge.

The only person who can make him not hold grudges is probably Qiao Xi, and maybe Xia Keke, but the latter will obviously not hit him, but may make him more inflated with all kinds of worship. The most important thing is that he

Xia Keke cannot be contacted now.

The poor little girl in the tenth-grade practical class of a key high school doesn't even have the right to bring her mobile phone into school. Fortunately, Qiao Xi doesn't have to go to high school and can still play with her mobile phone.

The video was connected very quickly. Before the first sound could be heard, the video screen was connected. "Hey, brat, what's going on?"

Not only Qiao Xi's voice, Qiao Yu also saw that Qiao Xi was not in his room, but in the living room. He could also hear the sound of soap operas coming from the TV. Obviously, his mother did not study in the evening today.

Qiao Yu immediately criticized with sadness: "Qiao Xi, I mailed you so many textbooks, reference materials and test papers, but you are lazy? It's evening self-study time! How can you watch TV?"

In the video opposite, Qiao Xi said angrily: "Do you want to check what time it is first? The scheduled evening study time is from seven to nine-thirty, and it's already nine-forty now. What's wrong with me watching TV during my break?

?」

Then Qiao Xi called in a long voice: "Teacher Qiao..."

Qiao Yu glanced at the time and said, well, I have nothing to say.

In fact, it was only nine o'clock after he came back. He checked WeChat and Weibo, and forty minutes passed before he knew it. This made Qiao Yu feel that he should review. With this time, he could finish today. Professor Li has read less than half of the subject materials given to him.

"Okay, don't worry about these small details." Qiao Yu looked serious, accepted the title of teacher calmly, and then said: "Do you know that I was on the hot search today?" "If you mean that Teacher Lan who specializes in typing Call me and tell me that you have become the joint training target of Yanbei and Huaqing, then I know." Qiao Xi turned sideways and replied lazily.

Qiao Yu continued to criticize: "Then how can you remain so calm? Do you know that this is a treatment that only comes once in a century? If it were another mother, she would be so happy that she would be publicizing it everywhere with a loudspeaker!

Qiao Xi rolled her eyes at the camera and replied lazily: "Didn't you say before you went to Yanbei that you were gold? Isn't gold treated like this everywhere? What's there to be happy about? Besides, when you went to Yanbei , everyone has already regarded me as a panda.

For people living in the railway community, is there any difference whether you are studying at Yanbei University or a joint training program between Yanbei University and Huaqing University? No, they are not Teacher Lan and cannot understand the difference, so you Who am I to show off to with a loudspeaker?"

See, Qiao Yu knew that it was Qiao Xi who could attack him.

It's not because his mother likes to hit him, or she habitually hits him, but Qiao Xi is very good at reasoning with him. She uses her very logical way to extinguish his surging pride.

Qiao Yu said dissatisfiedly: "Then you should praise me too, right?"

In the video, Qiao Xi seemed to change her sitting position to make herself more comfortable, and then she said calmly: "Then what's there to congratulate? For you, does it make any difference whether Yanbei University trains you individually or jointly?

You have set your goals a long time ago. These are nothing more than the intermediate process for you to achieve your set goals, right? You should know how far you are from the goals you have set. How can you have the nerve to let me praise you?

"Although what you said makes sense, I'm not happy anymore." Qiao Yu said with a straight face.

Qiao Xi blinked and said with a smile: "Haha...you sent me a video specifically, don't you just want to hear what I say? Why aren't you happy? It's so easy to break the defense without it. of."

Qiao Yu said without interest: "Okay, then you should take a rest after watching TV. I'm going to start working. You're right, I'm still far from my goal! Hey, I've taken on two projects now. You don't know, I suspect that Grandpa Shi almost regards me as his grandson.

"That's good. It just so happens that you don't have a grandfather. So is Director Tian as majestic as his father?

"You know, I have never experienced father-like majesty, but grandpa-like majesty is somewhat meaningful."

"Actually, they're pretty much the same. Your grandpa brought me up like this, and the words he told you were often repeated to me when I was a kid."

"That's pretty much it. Anyway, I had a pretty good time at Yanbei University. I was protected and no one dared to care about me even if I walked sideways. By the way, the senior brother I told you about last time is about to graduate. At the end of the month I have to defend my graduation, and I will most likely go to Yujiang University to teach after graduation."

"So your hot water will stop?"

"That's definitely not the case. I'm just curious who Director Tian will ask to be my neighbor, because my office upstairs will be vacant. "It seems you are very free."

"Did you not listen to me just now? I have two projects now, one each for Huaqing and Yanbei!"

"But you are still very free. If you were really busy, you wouldn't think about things that have nothing to do with you. Qiao Yu, I've seen you look serious."

"Well, I just haven't entered the state yet. You know, I just made a very powerful proposition. In fact, what I want you to praise me for today is not because I became a joint training target, but simply because I combined that person's The article that could have been published was ruined. In an aboveboard way, he even thanked me."

There was silence on the other side of the video for a moment, and then Qiao Yu looked at Qiao Xi with a particularly beautiful smile on her face.

"My son is so awesome! He will be like this in the future. You must learn from your grandpa in this regard. He will be upright and upright throughout his life and will never engage in crooked ways. It's a pity that I made him embarrassed.

"What shame? You gave birth to me, and you are the greatest mother in the world, the mother of human mathematics. In addition, let me tell you, grandpa has not been upright all his life. You have never played pool with him. He went out to play. I’m not shy about using various methods, even the dirty ones.”

"Your grandpa heard this, let's see if he likes you or not."

"Just beat him. If he survives, he can beat me a hundred times."

"That won't work. I'm afraid I'll break you after a hundred meals. You should take better care of your health outside and live well.

"Don't worry. Now the security guards from Yanbei and Huaqing are protecting me. Do you know how safe I am? As for you, taking good care of your health is the last word.

"By the way, I have good news for you. Ever since I started reviewing high school knowledge, I have always had trouble concentrating, but I seem to have recovered a lot. I watched TV last night and I could remember the entire plot just once.

"Tell me earlier! Do you know what it's like to watch TV with you and have to watch it again many times every time? But I think it's not only related to reviewing high school knowledge, but also related to your quitting drinking. So I still can't drink alcohol. !

"I promise you that I won't drink again, don't worry. I'm fine by myself, especially since your Uncle Xia and Aunt Liu are so enthusiastic now. They will drag me in for dinner whenever they are at home, and I can't refuse. .In short, life now couldn’t be better.”

"Tch, where are you now? Let me tell you, with a son like me, your good days are still to come! Although you have not been able to marry into a wealthy family, your son will marry into a wealthy family in the future. Think about it, right? Very touching?」

"I'm not that demanding, I just want you to be good."

"Don't worry, I'm going to be busy! After all, rich families don't talk about it." "Go ahead, I'm watching TV."

"Don't watch it too late, you have to study by yourself tomorrow morning!" "I got it."

..

After hanging up the video chat with Qiao Xi, Qiao Yu felt that the previous slackness had disappeared without a trace. His whole body was once again filled with the power of struggle.

The competition with that man was just a small victory, and there are still many tough battles to be fought. Academic status cannot be achieved by making mistakes, and more achievements must be made.

He also needs to start seriously considering and preparing for ways to make money. After all, he will be eighteen in two years.

The age of eighteen has special significance in China, as it means that he can apply to register a company and really start his career. Of course, if you have a good idea in advance, you can also ask Qiao Xi to register a company.

In this way, when he is eighteen years old, he may become the second generation of rich people. In short, time cannot be wasted.

So Qiao Yu took out the subject information that Professor Li gave him today from his bag and began to study it seriously.

After reading the proposition, Qiao Yu's interest was piqued. It was indeed a very interesting topic: making a two-dimensional generalization of Chevalet's theorem.

Chevalet's theorem is actually very simple. The specific expression is that for any algebraic group G and its corresponding Lie algebra g, if G is a compact group or a complexization of an algebraic group, then under an appropriate group representation , there is a representation related to g.

To summarize, any irreducible representation of an algebraic group can be decomposed into a direct sum of its irreducible representations of Lie algebras.

Anyone who has been exposed to mathematics knows that Chevalet's theorem has many generalizations, especially in the fields of algebraic geometry and representation theory. They involve more general algebraic structures, such as reduced algebraic groups, commutative heaps and various geometric objects.

Those who have been exposed to mathematics should know that two-dimensional generalization can be understood as the expansion of dimensions, which is often related to the structure of the exchange heap. The exchange heap is a geometric object composed of exchangeable Lie algebra elements.

Therefore, the core content of two-dimensional generalization is how to use the properties of global functions to understand the geometric and algebraic structure of commutative heaps. The current working idea of ​​the team is to introduce Langlands duality and establish a connection between algebraic geometry and representation theory.

Of course, such a complex proposition cannot be solved so easily. It also involves the use of many tools and modern mathematical ideas. Qiao Yu read these materials with great interest.

In this way, he watched for three hours without knowing it, and also roughly understood the problem that the team is currently trying to solve: they need to prove that on a given exchange heap, all global functions can pass through the automorphism of the Whittaker layer to describe, and these automorphic structures are directly related to the representation of algebraic groups.

Obviously, just by looking at the question, you can tell that this process involves a lot of technical details.

The USB flash drive that Professor Li gave him and the many information on the network disk provided to him were all their previous failed attempts on this issue.

All this information was given to Qiao Yu. On the one hand, it is a method that is often wrong, and it may also inspire new entrants. On the other hand, it is naturally to train Qiao Yu. Even if those methods are not feasible, they are still useful in mathematics. It is the result of the collision of various mathematical ideas of the team and is of great reference value.

But Qiao Yu didn't plan to continue watching today, he didn't even plan to watch.

Because he always feels that those wrong ideas may imprison his thinking mode.

In Qiao Yu's view, since the three professors have tried so many methods before and failed to solve this problem, it is enough to show that they are likely to be restricted by various rules and regulations. Previously, he looked for loopholes in the proof of the geometric Langlands conjecture. At that time, my thinking was also imprisoned.

Always trying to solve problems within a specific framework.

But actually stepping out of that frame often leads to better results.

So after reading the paper information, Qiao Yu went to bed directly.

Although Professor Li said some nice words when handing him the information, such as placing great hopes on him, and there are several project teams around the world working on this topic, and they are under great pressure, so they just hope He is such a rare soldier.

But Qiao Yu knew very well that these words were actually meant for Mr. Yuan.

If you try to make the old man happy, he will look stupid if he really believes it.

Professor Li probably just thought that since the old man had convinced all the collaborators, he would treat the dead duck as a living duck doctor.

Anyway, after all the information has been given and all the beautiful words have been said, everyone still has to do what they should do.

If Professor Li and other collaborators really put all their hopes on him, then this project would not be his turn at all. Mr. Yuan must also know, but who doesn't like to hear nice words?

In short, although he had no idea, Qiao Yu still slept soundly.

Pressure? It doesn’t exist. Even if there is pressure, it will only happen after he comes back from IMO.

If three math professors didn't finish something in half a year, if he could finish it in a few days, people might not be happy. It's true that he can just take advantage of this time to relax.

As a result, he had just finished breakfast the next day when he received a strange call. Seeing that it was a number from Beijing, Qiao Yu reluctantly chose to answer it.

"Hello, are you Qiao Yu from the Mathematics Research Center? "Ah, yes, it's me. Who are you?"

"Oh, Qiao Yu, hello, I am Liu Hao, a student of Professor Zhang and the person in charge of the new cobalt-based catalyst project. The boss said that this time the research center recommends you to help us correct the model. When are you free today? Woolen cloth?"

Qiao Yu didn't expect that Director Tian would be so efficient. Qiao Yu didn't expect that the other party would be so anxious. "I have time at any time, so I'll do it according to your request."

"That's great, you can do it now. I'm here in the basic laboratory building. Oh, have you been here? "Not really."

"It's okay, where are you now?"
