Chapter 121: Anticipated Mathematical Exchange

Xu Yuan is certainly familiar with Qiu Chengtong, who is currently serving as a professor at the Chinese University of Hong Kong. The fact that he is the first Chinese winner of the Fields Medal alone makes many mathematics researchers excited.

Especially since the other party was a student of Shiing-Shen Chern, the mathematical master known as the father of differential geometry.

Speaking of which, the optimal transmission Monge-Ampere equation he studied is also related to the Calabi conjecture proved by the other party.

He really didn't expect that the other party would take the initiative to hold mathematics exchange activities with Qinghua Academy of Mathematical Sciences.

And the Fields Medal winner also specifically invited him to participate.

You should know that he is currently studying differential geometry, and it is absolutely rare to have the opportunity to consult Professor Qiu Chengtong.

So the thought stayed here, and he agreed to it without any hesitation.

"Mr. Yang."

“I am willing to participate in this exchange activity.”

"I guessed that you wouldn't refuse. Old Qiu spoke very highly of you on the phone." When Mr. Yang heard Xu Yuan's answer, his smile widened.

It was then that Xu Yuan remembered that Mr. Yang had previously co-led the work of the Institute of Mathematical Sciences at the Chinese University of Hong Kong with Professor Qiu Chengtong, so they were naturally very familiar with each other.

Just as I was thinking about this, Liao Fangyi's voice came from the side again.

"I will lead this exchange activity. In addition to you, a dozen students from the college will be selected to participate."

"The timeline is tentatively about a week."

"I have no problem." Xu Yuan nodded without any objection.

As soon as he finished speaking, Mr. Yang added: "Don't be shy when you get there. Just think of Professor Qiu as your mentor. You can ask him any questions you have in mathematics at any time." It was like an elder giving instructions to a younger person.

Xu Yuan's acquisition of knowledge is like throwing a sponge into water; he naturally won't waste any opportunity.

It can be said that even if Mr. Yang did not say these things, when the time came he would definitely not be too shy to ask for advice when facing Professor Qiu Chengtong.

Definitely make full use of this exchange time to improve my understanding of differential geometry.

However, he still expressed his gratitude to Mr. Yang when the words came to his mouth.

"I remember."

After arranging this matter, as it was lunch time, Mr. Yang couldn't keep Xu Yuan in his office for too long, so he asked him to go back to prepare for next week's communication.

……

The mathematics departments of the two universities held an exchange activity, and the relevant news was announced on the official website of the school on the same day.

When the students of Qinghua School of Mathematics and Science learned about this, they were also very excited.

Many people signed up without much hesitation.

After all, in addition to discussions between students from the two schools, the exchange activities also provide the opportunity to listen to lectures by Professor Qiu Chengtong, which is an opportunity that is not always available.

Even after the news reached Yenching University, many students from the Department of Mathematics expressed envy.

I regret why I didn't take them to play.

As for the selection of students to participate in exchange activities, it is naturally based on their usual grades and performance.

From undergraduate to graduate students, the total number is about twenty.

What surprised Xu Yuan was that he saw Liu Yang's name after the shortlist was announced over the weekend.

If you think about it carefully, it is normal for Liu Yang to be selected. This is mainly because everyone's attention is usually shifted to him, so naturally they will not pay too much attention to Liu Yang in the dormitory.

But since he stopped taking normal exams, Liu Yang has been the best student in the class.

Last year, he participated in the Higher Education Society Cup and won a national award, which can definitely be called excellent.

-

"You two are so cruel to leave the dormitory leader at home like this."

On the weekend, in the boys' dormitory of Zijing Apartment, Li Zhenya looked at Xu Yuan and Liu Yang who were packing their clothes. He pretended to be very sad and spoke indignantly.

It’s okay that Xu Yuan doesn’t have time to participate in dormitory activities, at least the three of them are inseparable.

After nearly two years, I've become accustomed to it.

But no one expected that this time even Liu Yang would betray the organization and go to Hong Kong with Xu Yuan to participate in an exchange activity.

In this case, he and Wang Haitao would be the only ones left in the dormitory.

As soon as he finished speaking, before Liu Yang and Xu Yuan could respond, Wang Haitao, who was sitting next to the computer, spoke first.

"It's okay, Dormitory Master. You still have me with you."

Upon hearing this, Li Zhenya cast a look of disdain at Wang Haitao, and then the whole person felt like a frost-bitten eggplant. He sat in his chair and talked to himself, feeling like a shrew.

"We're going to spend a week together this time, and everyone in the dormitory feels like something is missing."

"I signed up to participate, but I wasn't selected."

"This exchange activity is incomplete without me."

"Maybe it's because we both failed a course before." Wang Haitao thought for a moment and added.

Although it is true, it hurts to hear.

Xu Yuan had long been accustomed to Li Zhenya's usual funny style, so he zipped up his backpack, turned around and looked at him with a smile on his face, and replied, "It's only a week, we'll be back soon, so I'll leave it to you two to look after the house this time."

"I still need to talk to Yu Ran."

After saying that, he no longer cared about Li Zhenya, Wang Haitao and the others, and immediately opened the dormitory door and walked outside.

This time he went to the Chinese University of Hong Kong for exchange and study, which meant that he would not be able to see Chen Yuran for seven days next week. In order to avoid the other party worrying about him, he must inform her in advance.

At this time, Liu Yang in the dormitory hurriedly said, "That dormitory head Haitao, wait for me to go over there and bring you gifts."

To be honest, Liu Yang was very excited to be selected to participate in this exchange activity.

In addition to being a great opportunity to improve my own math skills, what is more important is that I can participate with Xu Yuan.

Originally, seeing that Xu Yuan was growing faster and faster in mathematics, he had completely given up on catching up with Xu Yuan. Now, participating in this kind of event, to some extent, has put them back on the same starting line, which can be regarded as indirectly fulfilling his unrealistic dream.

Li Zhenya was just talking, of course. He was also happy to see Liu Yang being selected.

After all, they have all seen Liu Yang's performance. Although he works very hard in his studies and tries to improve his grades in mathematics courses, the gap between him and Xu Yuan is getting bigger and bigger.

It can even be said that even the back is almost invisible.

Although this does seem cruel to Liu Yang, it is the fact that no one can do anything about it.

Fortunately, Liu Yang later let go of the matter.

Otherwise, you would worry that the blow would be too severe and you would choose to change your major.

Therefore, when he saw Liu Yang was serious, he quickly said, "I just said that casually. We are so happy that you can participate in this exchange activity." After saying that, he patted Wang Haitao on the shoulder and asked, "Don't you agree, Haitao?"

"What the dormitory head said is right. There are many hidden talents in our dormitory. We can't always let Brother Yuan hold the fort."

"When you come back from the exchange, try to publish the entire paper."

Wang Haitao quickly understood what he meant and responded with a simple smile on his face.

In response, Liu Yang nodded vigorously and assured: "No problem."

that's it.

Early the next morning, twenty students from the School of Mathematics and Science gathered at the designated location on time, waiting to take the school's special bus to the airport for their flight.

Xu Yuan saw another familiar face in the crowd, it was Zhang Jundong, a student in Class 2 who was one year older than him.

It was precisely because of the partial differential equation problem he explained to the other party that he was able to decide on the topic of his graduation thesis and successfully prove the smoothness of the solution to the Monge-Ampere equation.

However, just as he was about to say hello to the other party, Zhang Jundong's voice had already reached his ears.

"Xu Shen."

"Finally seeing you again."

"Thinking about being able to attend the event with you this time, I was so excited that I couldn't sleep well last night."

It can be said that Zhang Jundong's admiration and respect for Xu Yuan has reached a very high level.

Especially knowing that Xu Yuan wrote a graduation thesis that could be published in the Annals of Mathematics in such a short time, he regarded him as his life idol and motivated himself to keep climbing to the top of mathematics.

So when he learned that the school was going to hold an event with Professor Qiu Chengtong, he signed up without hesitation.

Because he was constantly certain that Xu Yuan would attend, and he felt that this event was organized specifically for Xu Yuan.

These people also benefited from Xu Yuan's help and had the opportunity to listen to the lecture of the Fields Medal winner.

Another idea he had was to take this opportunity to ask Xu Yuan for advice again, hoping to make some progress on his graduation thesis.

Xu Yuan had a good impression of Zhang Jundong. He listened to everything he said and patted him on the shoulder in response.

"If you're too sleepy, you can sleep on the way."

As he was speaking, the department head Liao Fangyi, who was leading the team, also came over, accompanied by two lecturers from the college.

"Everyone hurry up and get on the bus and take roll call, don't delay the flight."

Liao Fangyi shouted to everyone, and then everyone took their luggage and got on the bus to the airport.

It is worth mentioning that their main purpose this time is exchange and learning, so the food and accommodation are all in the school just like normal classes. In addition, the food and accommodation in Hong Kong have been prepared, so Xu Yuan and his friends don’t need to bring much.

After successfully boarding the flight, we flew for more than three hours and landed safely at the airport.

As soon as I came out of the exit, I saw the airport pick-up staff arranged by the Chinese University of Hong Kong.

……

It was Xu Yuan’s first time to visit the Chinese University of Hong Kong. As soon as he entered the campus, he saw many red banners through the car window.

"We warmly welcome students from Qinghua School of Mathematics to come and exchange and learn."

It can be seen that the Chinese University of Hong Kong attaches great importance to this exchange and does not treat it perfunctorily.

After entering the campus and getting off the car, Xu Yuan was surprised to find that Professor Qiu Chengtong came to greet him in person. Upon seeing this, Liao Fangyi hurriedly stepped forward to greet them and introduced themselves to each other. Everyone's attention was immediately focused on him.

"This must be our mathematics prince Xu Yuan. I finally have the chance to meet him in person."

Qiu Chengtong made no secret of his affection for Xu Yuan. As he spoke, he immediately extended his hand and shook hands with Xu Yuan.
