Chapter 76 Number Theory Academic Conference [Subscription Request]

"Aren't you supposed to take the midterm exam today? Why are you here now?"

Tang Shihong was stunned when he saw Xu Yuan's expression. He obviously didn't expect Xu Yuan to come over at this time. He paused for two seconds and then asked.

He knew that Xu Yuan was going to take the midterm exam of the Department of Engineering Mechanics, so he specifically told him to wait until after he finished the exam at noon.

But now is exam time.

Xu Yuan noticed Tang Shihong's confusion and hurried to explain.

"Professor Xu only gave me one test paper. I didn't have to take the rest of the test after I finished it yesterday."

"So that's it."

"Then it seems that you should have done well in the exam." Tang Shihong nodded and felt relieved.

"Sit down first."

Then he asked Xu Yuan to sit down.

Lu Chunming, who came in with Xu Yuan, was treated as a transparent person by his tutor as if he didn't see him, but his mood was not affected at all, as if he was completely used to it.

Instead, he walked to the water dispenser familiarly and poured two glasses of water for his tutor and Xu Yuan respectively.

After finishing, he sat quietly in front of the computer next to him, allowing the tutor to talk to Xu Yuan alone.

The main character is a well-behaved and sensible one.

When Xu Yuanlin came, he was wondering what Tang Shihong wanted to talk to him about suddenly.

Now that we meet, I naturally won't keep any questions in my mind.

After sitting down on the chair in front of him, he took the initiative to ask Tang Shihong: "Professor Tang called me here for something?"

"I was just about to tell you."

When Tang Shihong heard Xu Yuan mention this matter, he stopped keeping it a secret and started explaining it immediately.

"The Mathematical Society plans to jointly hold an academic conference on number theory with Qinghua University and Yenching University."

"The location is at our Qinghua Academy of Mathematical Sciences."

"We will invite domestic and even overseas number theory scholars to participate, and you will give a report on the problem of the interval between infinite Carmichael numbers. The time should be set for next weekend."

After saying that, he did not forget to ask Xu Yuan for his opinion: "Do you have any questions here?"

When Xu Yuan learned that an academic exchange conference on number theory was going to be held, he was not surprised at all.

After all, this is a normal process, and similar academic conferences can be used to enhance one's influence in the international mathematics community.

In addition, being able to communicate and discuss with many mathematicians is also of great help to his own research in mathematics.

So I agreed quickly without even thinking about it.

"no problem."

"I feel relieved when you say that." Tang Shihong seemed to have guessed Xu Yuan's answer long ago and said with a smile: "There is about a week left before the report meeting. Do you need to prepare the content of the report in advance?"

"They're all in my mind." Xu Yuan shook his head with confidence.

If he were to talk about other things with those scholars, he might not be able to do so and would need to prepare in advance.

But as for the problem of infinite intervals of Carmichael numbers, it only requires people to go up.

You have to know that from the accidental encounter with Carmichael numbers, to the curious attempt to prove the final interval problem, to the successful inspiration of consulting literature and innovative sieve methods to complete the proof, the whole process is clearly remembered in my mind, and of course there is no need to prepare the report content in advance.

Tang Shihong undoubtedly believed in Xu Yuan, and he felt completely relieved after hearing this.

Then he contacted the Mathematics Council directly in front of Xu Yuan and informed them that Qinghua was ready.

It is better to seize the time to complete the docking work of all participants so as not to affect the time of the meeting.

At this time, Lu Chunming, who had listened to the entire conversation between the two, couldn't help but become very interested in this academic conference.

Although his area of ​​expertise is not number theory, it is a very good experience to be able to meet many scholars and professors in the field of mathematics.

So the next second he bravely asked: "Teacher, can I attend this lecture?"

If Lu Chunming hadn't said anything, Tang Shihong really wouldn't have noticed it, because he had never taken his eyes off Xu Yuan since he entered the door.

He glanced at his student's application and asked casually, "Can you understand the content of Xu Yuan's report?"

Just one sentence made Lu Chunming wilted and helped him face the reality.

When Lu Chunming heard this, the scene of showing the paper to Xu Yuan that day immediately emerged in his mind. He could not understand Xu Yuan's proof of the problem of the intervals of infinite Carmichael numbers at all.

So in order to avoid embarrassment, he decisively gave up his previous idea.

"Then I'd better just write my paper honestly and try to publish an SCI paper this year."

After saying this, without waiting for Tang Shihong to speak, he decisively sat back and continued to study his graduate thesis.

Seeing this scene, Xu Yuan also expressed sympathy for his counselor.

It seemed that ever since he called him "junior fellow", the pressure on him to be Tang Shihong's graduate student had been increasing.

Even before the time for graduation from master's program, I'm already being urged to write a paper and publish it in an SCI journal.

It can only be said that one is afraid of comparison in everything. With such an outstanding undergraduate freshman like Xu Yuan around him, Tang Shihong would inevitably dislike his graduate students and thus be more strict with them.

All Xu Yuan can do is work on mathematics, and he may have the opportunity to help revise the content of the paper.

After finishing the story, Xu Yuan did not stay in Tang Shihong's office for long. He said hello to him and his senior, then immediately turned around, pushed the door and left to return to the dormitory.

On weekend afternoons, Xu Yuan spent his usual time in the library, continuing to study sophomore textbooks such as complex functions and ordinary differential equations.

……

In the evening, as the midterm exams officially ended, the atmosphere on campus became lively again.

Especially Li Zhenya and Wang Haitao were in full spirits. They ran to the playground to meet the girls right after finishing their meal.

It seemed that he had completely forgotten what he said last night. Xu Yuan had long guessed that the two would end up like this, because neither Li Zhenya nor Wang Haitao were the kind of people who liked mathematics from the bottom of their hearts.

Choosing the Department of Mathematics is simply about finding a major.

After all, this situation is very common. For high school students who have just finished the college entrance examination, they have no plans for their future, and when choosing a major, they mainly follow the crowd or consider various reasons around them.

This is also the reason why many people choose to change their majors after school starts.

To be honest, it is rare that Li Zhenya and Wang Haitao insisted on staying in the Department of Mathematics.

Everyone has his or her own life trajectory, and forcibly changing it may not necessarily be a good thing.

So Xu Yuan didn't say anything. At most he would explain the questions to them during the next final exam.

the next day.

In the new week, Li Zhenya, Wang Haitao and Liu Yang have to catch up with the morning routine.

He got up early without being called, and even found time to go to the cafeteria for breakfast.

Although Xu Yuan was with them, he returned to the dormitory after eating.

Because he had received a notice from Xu Chongxing yesterday, requiring him to go to the Department of Engineering Mechanics to attend classes in the morning, and the results of the weekend exam would be announced at that time.

It just so happens that the theoretical mechanics course is at 10 o'clock, which is much easier than going to class at 8 o'clock in the morning.

Monday, November 2003, 11, Shaw Science and Technology Building.

Xu Yuan appeared in the classroom on time at ten o'clock in the morning. While waiting for class to start, he could hear many people around him discussing their grades.

Most of them are worried that they will fail the course and have to retake the exam.

I can only say that no matter which department the students are from, most of them are in this state when facing exams.

Soon, Xu Chongxing walked in from outside, still holding a teacup in one hand and a simple handbag in the other. He looked around the stage and noticed Xu Yuan's figure, a slight smile appeared on the corner of his mouth.

He put down the water cup while standing on the podium and waited until the classroom became quiet before starting to speak.

"Many people did terrible in the theoretical mechanics exam the day before yesterday. Did you listen carefully and see clearly in class?"

"Don't even think I'll give you a passing grade."

"As a student of Qinghua, I still need the teacher to give me grades in order to pass the course. It would be too embarrassing to tell others about it."

"I hope you can study hard in the second half of the semester to ensure that this situation does not occur again in the final exam."

As Xu Chongxing spoke these words in a deliberately stern voice, there was a burst of wailing from the audience.

"Did you really fail the exam?"

"No."

"I feel like I answered pretty well, I shouldn't fail."

"I should have reviewed intensively before the exam."

"Anyway, Xu Zhuangyuan failed the exam with us. It won't be so painful if you think about it."

……

The students in the class, who were originally looking painful, suddenly felt much better when they heard someone say this.

As the gold medalist of the International Mathematical Olympiad and the top scorer in this year's college entrance examination, he also published a paper in the Annals of Mathematics. This kind of gold content made them feel much more relieved when they failed the exam.

No matter how difficult the test Xu Yuan gave was, everyone failed anyway.

Thinking of this, many people looked at Xu Yuan with much friendlier eyes.

Xu Yuan remained calm as he listened to Xu Chongxing's words, and it was difficult for others to see any changes in his expression.

no way.

He was too confident about engineering mechanics.

It can be said that even if all the students in the major failed the course, he would not be there.

really.

Then everyone noticed that Xu Chongxing smiled, which was rare for him, and continued speaking in a completely different tone from before.

"Now I want to give special praise to a student, that is Xu Yuan from our class."

"Student Xu Yuan got full marks in this exam."

"Everyone applauded and encouraged."

As Xu Chongxing finished his words, the classroom suddenly became silent, and one could hear a pin drop.

It’s not that everyone didn’t applaud on purpose, but that they didn’t react at all.

"Xu Yuan got full marks. Isn't that a bit wrong?"

"I was in the same examination room as him, and he gave up the exam and handed in his paper halfway through."

"Could it be that……"

"That was a question set by Professor Xu himself. It's a bit too abnormal to get full marks for it."

Xu Chongxing listened to the whispers from the audience and immediately frowned and started to lecture.

"Look at Xu Yuan, he has mastered professional knowledge to this level just by self-study without attending classes."

"Don't you feel embarrassed and panic?"

After hearing Xu Chongxing's confirmation again, everyone finally reacted. Although they were thinking, "Professor, that's not what you said before," they also had a deeper understanding of Xu Yuan.

It turns out that the real academic genius has long exceeded their cognition. No wonder he can achieve such excellent results.

The next second, a classmate took the lead in applauding, and suddenly a deafening sound was heard in the classroom.
