Chapter 66 Contribution to Annals of Mathematics [Subscription Request]

"By the way, why hasn't Xu Yuan come back yet? Did they tell you what they were going to do this morning?"

Li Zhenya sat at the table under his bed, looking at the empty bed of Xu Yuan and asked Wang Haitao and Liu Yang. As the dormitory head elected by everyone, he, Li, had the responsibility and obligation to care about every roommate.

"I don't know. He just said he had something to do. I thought he would have lunch with us at noon."

"I know the same thing as you do." Liu Yang turned his head and continued.

During the twenty days of military training, the four of them basically went to the cafeteria to eat together.

Today is the first time that Xu Yuan has left the organization.

When he was at a loss for words, a bold guess suddenly emerged in Li Zhenya's mind.

He immediately started communicating with the other two people in a mysterious manner.

"Do you think Xu Yuan might have met a girl from another department and left us at noon to have lunch with the girls?"

Wang Haitao thought for a moment and agreed: "I think it's possible. Brother Yuan is a big shot among the freshmen."

"Certainly not."

"Brother Yuan just wants to study peacefully, how could he take the initiative to look for girls from other departments?"

"Maybe he went to the school library." Liu Yang shook his head and defended Xu Yuan very firmly.

Although Xu Yuan went to the computer room almost every day during the military training, looking decadent, the idol image in his heart had not completely collapsed.

Naturally, I don’t believe that Xu Yuan has also fallen for beauty.

"Why don't you give her a call and ask? She has a substitute class in the afternoon." Wang Haitao suggested.

"It can only be this way."

Li Zhenya nodded and was about to take out his cell phone when the dormitory door was suddenly pushed open from the outside and a familiar voice was heard.

"What are you guys talking about? It's so lively?"

Xu Yuan, with a slightly bulging belly, walked into the dormitory, stood in the middle and asked Li Zhenya and the other three people.

Lu Chunming was so enthusiastic in the cafeteria that he ate so much at lunch that he even felt uncomfortable sitting down.

Seeing Xu Yuan just coming back, Li Zhenya immediately changed the subject and said, "We were talking about where you went."

Xu Yuanyuan thinks that his biggest shortcoming is that he is too honest and never lies when faced with questions from others.

Therefore, he had nothing to hide this time and answered truthfully: "I'm going to ask Professor Tang from our mathematics department to help me look at a paper." He portrayed himself as an honest, three-good college student.

"I didn't expect you knew Professor Tang."

"I met him when I participated in the Mathematical Olympiad before, and I've attended his classes." Xu Yuan nodded in response.

Unlike Li Zhenya, Liu Yang was about to say that his previous judgment was correct, but then he really realized that the focus of this sentence was the paper, so he looked at Xu Yuan and asked a follow-up question.

"What paper? Brother Yuan, are you writing a paper?"

"I took some time out during military training to write a paper on number theory." Xu Yuan answered casually.

At this time, Li Zhenya and Wang Haitao also reacted, and joy suddenly appeared on their faces as they congratulated Xu Yuan.

"That's amazing! You finished it so quickly! We'll have a reference template for our graduation papers in the future."

"Brother Yuan is really efficient. I thought it would take several months to finish it."

When they followed Xu Yuan to the computer room that day, they already knew that Xu Yuan was writing a paper.

However, the content of the paper is unclear.

In their opinion, Xu Yuan probably just wanted to familiarize himself with paper writing methods so that it would be easier for him to complete his graduation thesis and defend it in the future. This was completely different from the situation of those professors submitting papers to journals for awards.

After listening to what they said, Liu Yang finally understood the true situation.

I asked tentatively, "Brother Yuan, are you writing papers in the computer room every day during military training?"

"Yes."

"The computers in the school computer room are not suitable for playing games. Let's wait until our sophomore year to buy a computer," Li Zhenya added, taking over Xu Yuan's words.

After getting such a result, Liu Yang felt a little complicated.

He previously thought that Xu Yuan had become addicted to games and had become a little decadent recently, so he wanted to take the opportunity to study harder, hoping that he would have a chance to surpass Xu Yuan in the midterm or final exams.

The story of the tortoise and the hare is one we have all heard since childhood.

Who would have thought that Xu Yuan didn't play games at all, but instead progressed from doing exercises and reading textbooks to writing papers.

I thought the rabbit took a nap in the middle of the race, but who would have thought that it had already switched to a higher level track.

However, he still had a question in his mind, so he turned his gaze to the dormitory head Li Zhenya and said, "Aren't you guys reacting a little too calmly? It's a math paper after all."

“Even if a senior student writes a graduation thesis, it probably won’t be completed that quickly.”

Liu Yang had been in contact with Xu Yuan for such a long time, and he had no idea how much stimulation he had received. But when he learned that the other party had completed a math paper and had Professor Tang give him guidance only during the little time he had to spare for military training every day, he was still shocked and gradually felt that he was getting further and further away from Xu Yuan.

In contrast, Li Zhenya and Wang Haitao remained quite calm even though they had known for a long time that Xu Yuan was writing a paper.

Just as he was thinking about the reason, Li Zhenya suddenly explained with a melancholy look on his face.

"You don't understand Liu Yang."

"When I saw on the school forum that our principal personally sent Xu Yuan an admission letter, I was completely elevated. No matter what amazing things Xu Yuan did, I thought it was normal."

Li Zhenya had long known that Qinghua University had a Shuimu Qinghua Forum, which was not much less lively than the Tianya Community.

That day, I went to the school computer room with Xu Yuan. Since we couldn’t play games, we browsed the school forum.

As soon as I opened it, I saw the most popular post, which was the admission letter sent to Xu Yuan by the principal Gu Binglin himself.

Who can enjoy this kind of arrangement among so many Qinghua students? If Xu Yuan gets the perfect score in the Olympic Games and becomes the representative of the freshmen of this year's three-character class, others may have a chance to complete the replica and surpass, but it is probably difficult for the principal to send an admission letter to a second student.

Being greatly shocked in his heart, he was naturally immune to Xu Yuan's shock.

"Brother Yuan."

"Was your admission letter delivered by the principal himself?"

"How could it be false? There is a photo of Brother Yuan and our principal on the school forum." Wang Haitao emphasized confidently.

This was the first time Liu Yang knew about this, and his eyes were wide open to the maximum extent at this moment.

As far as he knows, admission letters are mailed to students.

Who would have thought that there is a special delivery service for principals.

Who wouldn’t feel jealous if they are a student?

Seeing that what several people said was getting more and more outrageous, Xu Yuan had to quickly change the subject.

"You guys will run out of steam if you keep talking. Hurry up and get ready for your advanced algebra class this afternoon."

After he finished speaking, he didn't listen to anything they said anymore and went straight to the living room connecting the two dormitories, intending to do some exercise to relieve his hunger.

……

Lu Chunming was criticized a lot by Tang Shihong this morning, but he was very happy and excited.

It is a rare opportunity for a mathematics student to witness an undergraduate freshman solving a difficult mathematical problem. The key is that this freshman may very well be his future junior.

So much so that when I returned to the graduate dormitory, I was humming a little tune.

The Bauhinia Apartment project in the school has not been fully completed, and currently only the second and third class undergraduate students live there.

The dormitory for graduate students is in another building.

According to the specifications, master's students are divided into two rooms, while doctoral students are divided into one room.

Just as Lu Chunming pushed the door open, he heard his roommate's voice.

"What happened to you today that makes you so happy?"

"Just this morning, a fortunate thing happened in the mathematics community. The Carmichael number interval problem in the field of number theory was proved." Lu Chunming moved his chair and sat next to his roommate with excitement on his face.

"It's definitely not you who proved it." said my roommate seriously.

Lu Chunming generously admitted: "Of course it wasn't me, it was a freshman in the three-character class I taught."

But as soon as he finished speaking, the roommate opposite him raised his hand and touched his forehead naturally.

"Stop it."

"Although I'm not from your mathematics department, I still know the problem of the interval of Carmichael numbers."

"Can the freshmen in the three-character class prove it?"

"If you said it was your mentor, Professor Tang, I would believe it."

After making sure that Lu Chunming did not have a fever, he turned back to the computer in front of him after saying this.

When Lu Chunming saw that his roommate actually questioned what he said, he felt a little unhappy when he first heard it, but when he thought about it carefully, it was really hard for anyone to believe such a thing.

"I know you won't believe it. When the paper is published, you will understand whether what I said is right or not."

Finally, I said this with confidence and stopped arguing about it.

-

the next day.

After receiving a call from Professor Tang, Xu Yuan went to his office again during his free time.

This time he went straight upstairs and knocked on the door.

"Please come in."

I heard the familiar voice of Tang Shihong coming from inside, and then I pushed the door open.

Lu Chunming is not here today, and Tang Shihong is the only one sitting in his office.

When Tang Shihong saw that the person coming was Xu Yuan, he immediately smiled and stood up and said, "Your paper is very well done. I didn't help you correct a few formatting issues, so I won't shamelessly add my name. You are both the corresponding author and the first author of the paper."

"That wouldn't work. If you hadn't said that at the presentation..."

"Let's not talk about this anymore. Have you decided which journal to publish in?" Tang Shihong raised his hand to interrupt Xu Yuan and asked with a smile.

Seeing Tang Shihong say this, Xu Yuan had no choice but to stop mentioning the matter of being listed as a figurehead.

After a little thought, I came up with the name of a mathematics journal.

"I'd better submit it to Annals of Mathematics. That's the journal that Pomerance and three other mathematicians used to prove the infinite number of Carmichael numbers."

"Annals of Mathematics is one of the four top journals in the field of mathematics and is completely worthy of your paper." Tang Shihong nodded in approval.

In the following time, Xu Yuan directly used the computer in the office to submit the paper to the mailbox of the Annals of Mathematics, and naturally filled in the School of Mathematics of Qinghua University as his current school.

After completing the last step, he just needed to wait patiently for the reply from the Annals of Mathematics.

Since it is under the name of Qinghua School of Mathematics, and it is a proof of a relatively important problem in the field of number theory, I think the review time for the paper will not be too long.
