Chen Zhuoyang's words were just a little artistically processed. Qiao Xi's understanding ability was very strong, but how could she go so far?!

"Mom, you are wrong! His expression was affirming my mathematical talent! Because with a few words I made him realize how important I am to the world of mathematics, and he hopes to get my guidance in the future, so that's why

"That's what I said." "Oh, that's it. Just get used to it, but boys should also remember to protect themselves outside."

"This is Yanbei University. Do you know how strict the security at the entrance is? I'll scare you to death if I tell you!"

"Okay, anyway, take care of yourself and don't scheming against others. I don't know how strict the security at Yanbei University is, but I know there are very smart people there. Playing smart will only make people dislike you." "Don't worry.

"Small cleverness is what I used in elementary school. In college, I will only use great wisdom to conquer them!"

"Okay, come on! By the way, yesterday your eldest cousin heard the news about you from somewhere. He knew that you were going to Yanbei University, so he called and asked about you. He also asked if you were free during the summer vacation. He wanted to

Take his son to Yanbei University to experience the atmosphere." The topic changed a bit abruptly. Fortunately, Qiao Yu was very used to Qiao Xi's way of chatting, so he immediately replied: "What he thinks is so beautiful! I

You’re not going home during the summer vacation?”

"Well, that's what I told him. I'm just reminding you in advance to avoid being rude online in the future."

Qiao Yu said disdainfully: "No, this is not me singing a song, it's reporters who want to report on me, and there's nothing I can do about it. It's hard for a future great mathematician, the star of hope of China, to keep a low profile. Besides, I

I just like to see them see me getting rich, but they can’t get any benefits and can only say bad things about me behind my back. So I have to be cool!”

"Well, it seems to make sense. Coco said the same thing today. She also said that if your eldest cousin dares to kidnap you, she will be responsible for helping our family to scold him." Qiao Yu: "How can she scold people? Just a few times. Well, forget it, I’ll go to bed first, I have to attend a lecture tomorrow.”

Qiao Xi: "Oh, good night, son."

Qiao Yu: "Good night, Mom!"

Putting down the phone, Qiao Yu stood up, picked up the toothbrush basin and towel, and planned to wash up and go to bed. But when he reached the door and held the doorknob, he suddenly changed his mind.

Damn, he is so outstanding that the opposite sex is thinking about him every day and wants to help him scold him, so why do he pay so much attention to personal hygiene? Forget it, just go to bed, it is still very cold outside the capital at night in the winter. .

So I put the toiletries back with peace of mind, jumped directly onto the bed, and went to sleep! The lecture time for the next day was from 9 to 11 in the morning, two hours.

Qiao Yu regained his good habits and climbed out of bed at 6:30 in the morning.

You can do whatever you want in the evening, but you still have to take care of yourself in the morning. After all, this is the first time in your life to attend a lecture. When Qiao Yu went out to wash up, he specially picked up the facial cleanser that was still stuffed in the box. A bottle of this thing Qiao Yu It can be used for more than a year, not because he is very economical, but only on important days, he doesn't use it at all.

Facts have proved that although washing your face with cold water is painful for the first time, it makes you shiver from the cold and makes you feel refreshed and refreshed. Especially the face that uses facial cleanser feels tight and dry. And comfortable.

After washing up, Qiao Yu did another set of radio gymnastics outside the house. After moving his whole body, he went back to the house, sat down at the table, went through what he had thought about yesterday in his mind, and then took a few more pictures. Manuscript paper, translating everything he wrote yesterday into English.

There was no other way. A professor from New York University came to the research center to give a lecture. Qiao Yu felt that he should acquiesce that the other party did not understand Chinese. After all, Chinese is really not easy to learn, especially for foreigners. He took a stack of papers filled with It seems a bit overwhelming to ask the other party for advice without having a Chinese manuscript paper.

At half past eight, Lao Xue arrived at Qiao Yu's temporary dormitory on time. "It's so early, Teacher Xue."

"The lecture started at nine o'clock. It's now half past eight. It's very early?"

"Isn't the lecture in the research center? Isn't it just a few steps away?"

Old Xue was speechless. He looked at Qiao Yu and asked, "So you plan to go in with the professor who is giving the lecture, right? Professors will go to the lounge in advance to wait for the lecture to start. Can't you wait in the conference room for a while?" Well, considering that Qiao Yu is only fifteen years old, it's understandable that he doesn't think that carefully, Xue Song reminded himself in his heart.

In fact, it's not surprising that he always has strict requirements for Qiao Yu. It's just that Qiao Yu's behavior often makes him subconsciously ignore this guy's age. "Oh, that's right. Then wait a minute. I'll use what I'm going to use today. Prepare your things."

After saying that, Qiao Yu quickly started to put away the conjectures he had just sorted out in English. He had to put them in order. If he put them in the wrong order, he was afraid that others would not understand his thoughts at that time. To be honest, it was only one night, and he had just put them in order. While translating, he felt that his brain might have been a little too excited last night.

The things I came up with have an indescribable messy beauty.

"Just bring a notebook and pen. What else do you need to prepare? Wait, what is this?" Xue Song keenly noticed Qiao Yu's densely packed manuscript papers.

"This is what I thought after reading Professor Robert's paper yesterday. I plan to discuss it with the professor later. Maybe we can take this issue a big step forward!" Qiao Yu said confidently.

"Let me take a look first." Xue Song glanced at Qiao Yu suspiciously. To be honest, he still didn't believe that Qiao Yu just read the paper all afternoon and gained some new insights into this research direction. But Qiao Yu I've proven myself many times, but I can't always keep my words to death.

"Okay, please read it from the beginning, otherwise it will be chaotic."

After receiving the draft handed over by Qiao Yu, especially the first proposition about constant C, Xue Song couldn't help but look up at Qiao Yu in surprise, wasn't he? This is too outrageous?! He immediately looked away, I continued reading, and then I calmed down when I saw the big question mark following it.

Oh, it was just an idea...it shocked him.

Then he quickly scanned Qiao Yu's thoughts without changing his expression, and Xue Song looked confused.

What did he just read? To be honest, he could roughly clarify Qiao Yu's thinking. After all, he studied Diophantine equations, but this method... Silently rearranged the manuscript paper and handed it to Qiao Yu then said in as calm a tone as possible: "Let's go."

"Okay." Qiao Yu picked up the things and followed Xue Song out of the door. On the way to the lecture conference room, Qiao Yu couldn't help but asked cautiously: "Teacher Xue, is my idea wrong? How do you feel after reading it? Weird?"

Xue Song took a deep breath and considered for a long time before answering: "I can't say whether it's right or wrong, because I don't know if you are further complicating the relevant issues. After all, I haven't studied it in depth, Professor Peter Schulz "Those achievements." "Hmm? What does complexity mean?" Qiao Yu asked humbly.

Xue Song thought for a moment and replied: "You should know from reading Professor Robert's paper yesterday that our similar research is mainly based on the methods and tools of classical number theory and algebraic number theory. For example, the use of classical tools is mainly class field theory, circle theory, etc. Domain, unit group theory, etc.

Even if it involves some modern tools, that is, elliptic curve theory, modular forms, etc., in short, such tools have covered the key ideas of similar problems, so they will not rely on Peter Schulz's theory. Line, Basic concepts of modular form and Lieq group theory.

So what you are doing, how should I put it, regardless of whether it is successful or not, of course I cannot judge whether it is successful or not, but what is certain is that the proof process will be extremely complicated. I don’t know whether it is a good thing or a bad thing if it is successful. ." Qiao Yu blinked and asked, "Why would it be a bad thing if it was successful? Isn't that why more advanced mathematical tools are created to be used?"

Xue Song glanced at Qiao Yu and said expressionlessly: "Because that means that in doing this kind of research in the future, Schulz's theory may become indispensable, but it is difficult to fully understand his theory, and This means that the threshold for studying related issues will be raised again in our generation.”

Qiao Yu suddenly realized, and said: "Oh! I understand, that is to say, if I succeed, you may have to learn Peter Schulz's theory from scratch in the future, right?" Xue Song glanced at Qiao Yu Yu glanced at him and didn't bother to talk to him. This child was getting more and more over the top.

But Qiao Yu was obviously more excited, and said emphatically: "No, Teacher Xue, you can't refuse new things! Only by thoroughly studying other people's things can we create newer things based on theirs. Come on. If I succeed and you want to learn this, I can teach you! It’s just like you giving me advice, I won’t charge you!”

Obviously, Professor Xue didn't appreciate it very much and scolded him directly: "Shut up!" Qiao Yu was a little aggrieved, but he was really too embarrassed to speak anymore.

However, my mind was thinking about the topic studied by Senior Brother Chen that the instructor mentioned yesterday.

Old Xue is already a professor, and there is nothing he can do about his inability to learn, but Senior Brother Chen is different. If he can follow the same pattern and find a way to solve the problem that Senior Brother Chen is studying, wouldn't it mean that Senior Brother Chen is still there? Before graduation, do I have to re-learn Peter Schulz’s theories?

I heard from Lao Xue that this theory is so advanced, so the extremely talented Senior Brother Chen must be grateful to him, right?

But he has to speed up, otherwise what if he refuses to accept such an advanced concept when Dr. Chen graduates successfully and finds a job? Then wouldn’t all his sincerity be paid to the dog by mistake? With Qiao Yu Walking up the stairs, Xue Song suddenly felt regretful when he found that this boy had really remained silent.

By the way, were you too harsh on the child just now? It would be bad if it dampened his enthusiasm.

Although this kid's words are very irritating, at least some of what he said is indeed correct. If more advanced tools can solve the problem, then you must still learn it, otherwise you will only be farther and farther away. And... Fifteen years old! It’s the age to be bold and bold. But Xue Song was too embarrassed to apologize directly, so he could only ask in a deep voice: "What are you thinking about?"

"Tell Professor Xue, I'm wondering when Senior Brother Chen will graduate with his PhD." Qiao Yu replied subconsciously. "Why do you care about when Senior Brother Chen will graduate?" Xue Song asked with a frown, this was very confusing. .

"Um..." Qiao Yu hesitated a little. Although he was doing it for the good of his senior brother from the bottom of his heart, Old Xue's attitude just now made him a little unsure whether Old Xue could understand his painstaking efforts for his senior brother. "This Is it difficult to answer?" Xue Song couldn't help but ask again.

Qiao Yu quickly shook his head and replied: "No, I'm just thinking that one method can be used to solve all problems. If I can use this theory to incorporate things like surfaces and manifolds, I can create more solutions for my senior brother." Will it be easier for him to graduate if he has tools to solve problems?"

Xue Song opened his mouth, too lazy to say anything.

He must admit that his worries just now were in vain. This boy's enthusiasm is not easily dampened. No matter what, it is Mr. Tian's student after all...

At this moment, Xue Song was even a little lucky that he didn't try to deceive this kid into his sect, otherwise he would probably be very tired for the rest of his life. Really, after getting to know each other, Xue Song no longer dared to speculate on Qiao Yu's story. What are you thinking about every day in your little head?

He even wanted to ask Qiao Yu for Lan Jie's contact information and ask the high school teacher how he usually dealt with Qiao Yu. "Teacher Xue, what do you think..."

"Stop talking nonsense, this is the conference room. Come in with me."

Qiao Yu secretly stuck out his tongue behind his back, "Hey, old Xue has become old-fashioned and doesn't like him at all..."

Today's lecture is arranged in a medium-sized conference room.

As soon as you enter the door, you can see a blackboard in the middle of the podium and a screen on each side.

At this time, Senior Brother Chen, whom Qiao Yu was thinking about, was already debugging the equipment on the podium, probably to ensure that Professor Robert's PPT could be properly projected on the screen when the lecture began. This made Qiao Yu feel a little emotional.

He suspected that Peter Schulz obtained his master's and doctorate diplomas quickly just so that he would not have to work.

Turning his head and looking at the seats under the rostrum, Qiao Yu roughly counted and found that about fifty people could sit there. However, except for a row of tables in the first row, there were only stools in the back. Let him Surprisingly, he and Lao Xue were not the first to arrive. At this time, there were already more than thirty people sitting in the conference room.

Except for the empty seats in the first row, there seemed to be not many seats left in the back.

Normally, he didn't know where these people were hiding. Anyway, Qiao Yu felt that he hadn't met many people in the past two days. What surprised him even more was that he saw three senior sisters.

Qiao Yu almost couldn't help but take out his phone and take a photo to show Lan Jie...

Who said there are no girls in the Mathematics College? You must be overgeneralizing.

When attending a mathematics lecture, you can easily see three senior sisters. This is enough to show that good people cannot see girls when they are studying. It is not a problem of mathematics, but a problem of the school. Shuangdan University must review... Qiao Yu and Lao Xue also attracted the attention of many people, especially Qiao Yu.

Maybe these guys didn't expect that a young college student like him would come to the lecture, right? Qiao Yu thought to himself, and then walked towards the back row of the conference room. There was no way, he was used to sitting in the chair when he was in Tieyi Middle School In the back row of the classroom, where the teacher didn't pay much attention, Xue Song grabbed me.

"Where are you going? Our seats are over there, on the right!"

"Ah?" Qiao Yu was stunned for a moment, then obediently followed Xue Song and sat in the rightmost seat in the first row.

Well, it's nice to have a table in front, not because of the mineral water on it, but mainly because it makes it easier to take notes.

Qiao Yu didn't bring his laptop. He only brought a serious notebook that cost 12 yuan a book and could only be used for taking notes, a water-based pen, and five sheets of A4 manuscript paper for summarizing his mathematical ideas. The main thing was to listen to the lectures. Use your brain.

While Qiao Yu was sitting there, people came in from time to time. Teacher Xue was right. Qiao Yu observed that by 8:55, the entire conference room was almost full, and there were even people standing in the aisle. Also. Includes first row position.

Everyone who came in would look at him intentionally or unintentionally, and some professors came over to say hello to Lao Xue and chat with him.

Senior Brother Chen has also completed the debugging before the lecture, and then sat in a seat in the middle of the first row, separated by an aisle from his and Lao Xue's seats, but leaving the seat close to Lao Xue. Qiao Yu When he saw Senior Brother Chen walking down, he looked specifically at him. When their eyes met, Qiao Yu smiled kindly in return. Sure enough, Senior Brother Chen really regarded him as important as air.

When the lecture time came, Director Tian accompanied Professor Robert into the conference room. The two walked to the podium together, and then Director Tian picked up the microphone first.

"Hello everyone, today our Yanbei International Mathematical Research Center is very honored to invite Professor Robert Greene from New York University to give this lecture. He is an outstanding scholar in the field of number theory, especially on algebraic geometry and rational number points. Many breakthroughs have been made in the research of distribution problems.

Today, he will give us a lecture on the precise estimation method of the upper bound of the rational number point of a special curve. This problem not only occupies an important position in number theory, but is also closely related to many other branches of mathematics. Next, let us Welcome Professor Robert with a warm round of applause!"

After saying that, amidst the applause from the audience, Director Tian walked off the podium and sat next to Chen Zhuoyang, leaving the podium to Professor Robert on the stage.

At this time, Robert Greene had already sat on the podium after greeting the audience. After trying the microphone, he said in fluent English: "Thank you, Professor Tian, ​​for the introduction, and thank you all for coming.

Today I will share with you the latest results of my team and I on estimation methods for the upper bounds of rational number points on a special type of curves. This issue has always been a very important topic in modern number theory, especially in understanding the properties of curves. A profound impact, I hope..."

Xue Song, who had been sitting there as steady as a rock, unceremoniously picked up Qiao Yu's prepared questions while Robert Greene was still giving the opening introduction on the stage, and handed it to Tian, ​​who was only across the aisle from him. Before Yan Zhen and Qiao Yu could react, half of the things in front of them were missing.

Well, whoever is the teacher is reasonable.
