God's Crown

Chen Tao smiled embarrassedly and scratched his head with his hands, "Isn't this the new clothes my girlfriend bought for me..."

"Hey, when did Brother Tao have a girlfriend?" An Yan didn't come to the University of Zurich for a semester, so it feels like everyone has changed a lot.

"Hey." Chen Tao smiled, "It's the relationship we established when we returned to China."

"Hey..." An Yan looked at Chen Tao and smiled happily, "I thought he was from Switzerland, but it turned out to be from Huaguo."

"That's right." Chen Tao nodded vigorously, "Of course it belongs to Huaguo."

"By the way, I have to congratulate you, An Yan. I originally wanted to do the twin prime number conjecture when I returned to school, but I didn't expect you to have already solved it."

"What's the matter, I just solved this problem by coincidence." An Yan pondered and said, "By the way, where is Brother Tao going now?"

"I'm going to go to the professor and get some materials. By the way, when did you come back? I heard you're about to graduate?"

"Yeah, I was just getting ready for breakfast."

"Then I'll get busy first." Chen Tao nodded to An Yan, and then left the dormitory.An Yan also followed Chen Tao out of the dormitory. After breakfast, he went to the library to search for some documents.

After finding the literature, An Yan began to look it up.While looking at the documents, he calculated.After returning to the University of Zurich, no one bothered him.

For several days, An Yan spent time in the library looking for information.After finding the information, he began to study number theory problems.

The problem of number theory is very complicated, he can only look at the data and calculate at the same time.Occasionally, I have to prepare for my graduation defense, but the time flies by.

After a while, it was time for the thesis defense, which meant that several professors raised a few questions after reading his thesis.This is not difficult. On the day of the defense, An Yan got dressed, washed up, and went out to the place where the graduation defense was held.

Professor Benson had been waiting at the door of the classroom for a long time, and when he saw An Yan coming, he waved to An Yan.

Walking to Professor Benson's side, An Yan softly called out to the professor.Professor Benson nodded seriously, and said in a low voice, "You have already been to an academic conference. I think you should have no problem with such a small scene. After reading your paper, everyone thinks it is very interesting."

"Of course, the questions they ask you won't be too complicated, you just need to answer them well. I believe that you should be able to do this." The professor paused here, looked at An Yan and continued Said, "Ann, I hope you don't let me down, this is the end of your time at the University of Zurich. I sent you to the University of Zurich, I have high expectations for you, and I hope this graduation defense, although it is not what Academic conference, but you have to show your full level."

"Your thesis is excellent, and I hope your graduation defense is also excellent."

"Professor." An Yan said gentlemanly, "Don't worry, I will definitely not let you down."

"That's good." The professor nodded slightly and walked into the classroom.

An Yan first tidied up her clothes, took a deep breath, and walked into the classroom.Several professors stared at An Yan, as if they were looking at some precious animals.He felt a little awkward, but he was too embarrassed to say anything.Everyone here is a boss, and he is a mortal, what can he say.

Silent, An Yan stood in front of several professors.

The professor nodded slightly at him and said, "Ann, we have already read your paper. It is a very good paper. This sentence is not because I give Professor Benson face."

All the professors laughed softly, and the unexpected humor eased An Yan's nervousness.He took a deep breath and said, "Professor, I'm ready."

"Then, let's start the defense."

After the professor finished speaking, he quickly entered the state, "I read this paper, you use the limit equation of the nonlinear partial differential equation to get the mathematical model, in the usual sense, we don't use nonlinear partial differential equations When it came to the limit equation, you even used the homogeneous balance method to get the result. Can you tell me about your thinking?”, “It’s such a professor.” An Yan paused when he said this, “Fluid mechanics Mathematical models of turbulent flow are usually described using nonlinear partial differential equations, and this is the only way to unravel turbulent flow."

"I was thinking, why can't I use the limit equation to calculate this thing."

"But you are using the Yang-Mills limit equation. This equation is used to solve the Yang-Mills existence and quality gap. Do you think it is reasonable to use it here?"

"First of all, professor, this is a set of limit equations, not the Yang-Mills equation. Secondly, my source of inspiration should be the Langlands program." After An Yan finished speaking, he looked at the professor.

After being corrected by An Yan, the professor didn't seem to be angry. Instead, he smiled and said, "So, you don't think you did anything wrong."

"Yes, at the beginning I wasn't sure if I had any results. But the final conclusion is already in the hands of the professors, and I believe I don't need to repeat it."

"That's right." The professor nodded in satisfaction.

Next, the rest of the professors asked a few more questions about turbulence models and nonlinear partial differential equations.

Until two hours later, An Yan was still able to answer these professors' questions with ease.After the graduation defense, Professor Benson stood up with a smile and said, "Congratulations, Ann, you have graduated."

"Thank you, professors." An Yan bowed slightly as a thank you to these professors.

Several professors seemed to be very satisfied with An Yan's answer. After looking at each other, they nodded slightly and agreed that An Yan could graduate from the University of Zurich.

"This is one of the most exciting graduation defenses I have ever seen." The first professor who asked a question said to An Yan, "This is one of the most exciting graduation defenses I have ever seen in my life. Ann, you did a great job. "

"Thank you, Professor, for your compliment." An Yan took a deep breath. Originally, he thought he couldn't speak fluently, but he didn't expect his brain to rotate very fast in such a short period of time.Even the questions raised by these professors, he was able to answer them with ease.

When thinking of this, he couldn't help but think of what Gou Liqun told him, that he just lacked some self-confidence.In fact, he is not weak, and can even be said to be very strong.

"Okay, An Yan, go back and rest." Professor Benson waved to An Yan, indicating that he could go back directly.

An Yan said to Professor Benson, "Then, Professor, I will go back first."

Leaving the professor, he took another deep breath.His college life has come to an end, but because he will stay at the University of Zurich for a period of time, he has not retired from the dormitory.He still has to live in the dormitory for a while, so go back to the dormitory.An Yan lay on the sofa and rested for a while.

Professor Benson's phone call came later.

"Ann." Professor Benson said on the other end of the phone, "Did you forget to go to the Göttingen Academy of Sciences in mid-April?"

"Not forgotten."

"I have one more thing to tell you."

"Professor, you said."

"After going to Göttingen, you cannot return to China immediately."

"What else is there for the professor?"

"

There is a math conference you need to attend in early May, which is the math conference at UC Berkeley, which is an international math conference.Many current important mathematicians have been invited, and even many mathematicians in your country of Hua will participate.You have been invited to give a one-hour academic conference presentation. After Professor Benson finished speaking, "Ann, this is not an opportunity that everyone can have. Countless mathematicians dream of a one-hour academic report meeting." "

"What is the theme of the meeting?"

"Twin prime number conjecture and derivative problems, I don't think this is a problem for you, Ann!"

"Thank you, Professor." An Yan hung up the phone. He originally planned to go back to China after going to Göttingen.Now I have to slow down again, but I don't know if my parents will complain about it.

To tell the truth, An Yan felt that she was a little bit annoyed by the fact that things that were clearly agreed upon changed again and again.Not to mention what others would think of him.

After thinking of this, An Yan took the phone and called An Zhi.He said wearily, "Dad, I may... I won't be able to come back in April. If there is nothing to do after May, I should be able to come back. If there is something to do after May, maybe it will be possible."

"Why, didn't you say you can go home after April?" An Zhi asked in confusion, "Is there anything else?"

"Yes, I was invited to a mathematics conference in May, so after I went to the Academy of Sciences in Göttingen, I had to transfer to the United States."

"Dad, you see, this matter is beyond my control."

"I know." An Zhi smiled wryly, "Be careful yourself, pay attention to your body, and go to bed early every night."

"Dad, I know." After An Yan hung up the phone, he breathed a sigh of relief, as long as his father didn't blame him.

After resting for a while, An Yan wondered if there was anything else he hadn't done?By the way, there is also the problem of number theory, the mathematical logic of this problem has not been done well.When thinking of this, An Yan rubbed his eyebrows.Forget it, he should get up and continue doing number theory. If this problem has not been done well, he may have to think about this problem all the time.It's better to solve this problem now, maybe there will be some time left to rest.

An Yan got up from the sofa, walked to the table, and was about to calculate with the draft paper when Gu Weize called, "Xiao Yan, when are you going to come back?"

Judging from Gu Weize's tone, he didn't know that he would not be back until May.I thought that An Yan would return to China tomorrow or the day after tomorrow.

"Xiao Yan, I happen to be on vacation tomorrow, can you come back? How about I pick you up at the airport?"

"Gu Weize." An Yan paused, and said in an apologetic voice, "I may not be back until April."

"Why?" Gu Wei was puzzled, he wondered if there was something wrong with An Yan, and if there was something, he couldn't force An Yan to return home.As An Yan's strong backing, how could he make An Yan sad?

It was even more impossible for An Yan to worry about him, so Gu Wei said, "Xiao Yan, if you really have something to do, then...it doesn't matter if you come back later."

"It's like this." An Yan knew that he might not understand it at all after talking to Gu Wei, but he still got more, "My professor asked me to stay at the University of Zurich for a while..."

"Why do you want Xiao Yan to stay at the University of Zurich for a while, hasn't Xiao Yan already graduated?"

"I don't know either. The professor just said that he was going to the Göttingen Academy of Sciences in mid-April. He said that someone from the Göttingen Academy of Sciences had called me before, but I hung up." An Yan said here with a hint of uneasiness. He said confidently, "I don't know what the people from the Göttingen Academy of Sciences are calling me for."

"Then Xiaoyan is going to Göttingen in April?" Gu Wei thought for a while, "Where is Göttingen?"

"Not far from Switzerland, just in Germany."

"Is there anything else to do after going to Göttingen in mid-April?"

"I also want to go to the United States to attend a mathematics conference and be invited to give a one-hour academic report. A one-hour academic report is very rare for this kind of academic report meeting, so I have to attend. If there is nothing else to do after attending, I should be able to go back to China." After An Yan finished speaking, she asked Gu Weize instead, "Aren't you in class now? Call me."

"Lessons haven't started yet." Gu Wei lowered his voice, "I'll secretly call you, so don't make a fuss about it."

An Yan burst out laughing, "I want to make a statement, so who should I tell. That's all right, you go to class." An Yan smiled, "Stop giving me nonsense."

"Yes, then I will go to class first, Xiaoyan, please send me a text message when you are going back to China."

"Okay, I see." An Yan hung up the phone, and finally started to calculate with the scratch paper.This calculation is more complicated.An Yan calculated while looking at his thesis.Then pondered for a while, and then calculated again.

Time passed quickly, and soon, An Yan and Professor Benson were going to the Göttingen Academy of Sciences.

When I found Professor Benson, he seemed to be talking to the students.Seeing An Yan enter the office, he glanced at him and said, "An Yan, wait a moment."

"Okay." An Yan nodded slightly, sitting aside and waiting for Professor Benson.

Afterwards, Roger took the salute and walked into the office, put the salute in front of An Yan and said, "Ann, this is the professor's salute."

"Thank you, Brother Roger."

"Thank you for what I did." Roger stared at An Yan for a while, that kind of gaze seemed to be something An Yan had never seen before, and he didn't quite understand why Roger kept staring at him like this, and that It was as if he had never known him before.

An Yan touched her face, and said curiously, "Brother Roger, is there something on my face? You keep looking at me like this?"

"It's okay." Roger smiled and said to An Yan, "You will know when you arrive in Göttingen."

"Ah..." Before An Yan had time to ask what he knew in Göttingen, Roger had already left the office.

The professor didn't know when he finished speaking, and when An Yan was thinking, he suddenly said, "Let's go, Ann, if it's later, it will be too late."

"Okay." An Yan followed the professor out of the office and headed for the airport.
