Chapter 108 Mr. Yang wants to see me
Tang Shihong looked at Xu Yuan, and finally softened his tone and no longer insisted on his opinion.

He sighed and said to Xu Yuan: "Since you have confidence, then do it."

As soon as he finished speaking, he added another sentence.

"But if you encounter any problems, remember to come to me anytime and we can discuss them. Don't just figure it out on your own."

"Thank you, Professor Tang. I will."

Xu Yuan nodded modestly in reply, and then without wasting any more time, he said hello to Tang Shihong and Lu Chunming, turned around, opened the office door, and left in a hurry to go to the library.

As Tang Shihong said, there are not many researchers on the Monge-Ampere equation involved in optimal transport theory.

Mathematicians' understanding of the field of partial differential equations still remains at the level of many years ago.

No new findings were found.

Compared with the fields of number theory, algebra and differential geometry, partial differential equations receive much less attention.

Since he had decided to study partial differential equations, he would definitely give it his all.

At this time, Lu Chunming in the office was watching Xu Yuan leave, and said to Tang Shihong with some concern: "Junior brother Xu Yuan chose the Monge-Ampere equation in partial differential equations as the topic of his graduation thesis. It is much more difficult than my graduate thesis. Will it be a blow to me?" He was quite concerned about his junior brother.

The difficulty of studying the Monge-Ampere equation is there. If there is no valuable new discovery in the end, it may affect Xu Yuan's confidence in mathematics.

If you were to give up on yourself after being frustrated, it would be difficult for you to make any achievements in mathematics in the future.

Tang Shihong also does not want to see the fall of mathematical geniuses, but he is more aware of the common problem of geniuses, which is that they are always full of confidence to face various challenges and are unwilling to waste time on those basic things.

Not to mention that Xu Yuan published his first paper in the Annals of Mathematics just after entering university.

"Xu Yuan is the most mathematically gifted student I have ever met. He will do everything he can to accomplish something he sets his mind to."

“Now we can only hope that he can make some discoveries in the field of partial differentials and successfully complete his graduation thesis.”

Tang Shihong shook his head and continued, "Maybe delaying graduation is not a bad thing for him."

According to the original plan, Xu Yuan would officially complete his undergraduate studies and graduate early after participating in the graduation thesis defense after the new year. However, if the graduation thesis is not completed by then, the defense would definitely have to be postponed.

All I can say is that sometimes experiencing some setbacks can help people grow faster and become stronger.

"It would be best if you could realize the difficulty of this topic as soon as possible. It might not be too late to change the topic temporarily."

After listening to his tutor's words, Lu Chunming continued talking to himself, but just as he was about to continue, he was interrupted by Tang Shihong's voice.

"How dare you say that to me? You must hand in the revised paper to me this week."

"Or else you will also be delayed in graduation."

After hearing this, Lu Chunming no longer cared about others and immediately expressed his attitude.

"Please don't do that, Professor. I will go back and revise my paper right now."

He said this without wasting even half a second and rushed out the door at full speed.

……

As time went by, while the freshmen of the four-character class were undergoing vigorous military training, Xu Yuan basically spent all his time in the library reading various international literature on partial differential equations.

In the dormitory, Li Zhenya and Wang Haitao often went out to watch the military training of freshmen, and they were very happy every time.

Because Liu Yang signed up for the Higher Education Society Cup, he often trained with two other teammates, so it was basically difficult to see him in the dormitory during the day.

After all, the Higher Education Society Cup usually starts in mid-September, so there are really only a few days left.

Simply put, the Higher Education Press Cup is a mathematical modeling competition for college students.

The participating team consists of three students from the same school, who are responsible for mathematical calculations, model building and thesis respectively.

After the competition officially begins, the official website will announce the corresponding topics. Participating teams need to complete computational modeling papers within a limited time, which is a kind of training for students' various qualities.

However, compared to other universities that attach great importance to the Higher Education Press Cup, not many students from Qinghua and Yenching University participate in the competition every year.

There will be no special team organized to represent the school in the competition.

Mainly for students from Qinghua or Yenching University, participating in academic competitions does not bring any practical results.

The biggest role is basically a sense of honor.

It is far less effective than doing research projects and publishing papers at top conferences, or doing horizontal corporate projects to solve practical problems.

Originally, Liu Yang wanted to team up with Xu Yuan to participate, but Xu Yuan was worried about his graduation thesis and would definitely not sign up.

What's more, Xu Yuan had published papers in the Annals of Mathematics and the top cryptography conference, so he didn't need any competition to prove anything.

"Liu Yang will have to stay up late today. I don't know if he can win the Higher Education Society Cup."

September 2004, 9, Qinghua University, Bauhinia Apartment Male Dormitory.

Li Zhenya was sitting in front of the computer in the dormitory and talking. He was very concerned about Liu Yang, the only person in the dormitory who had signed up for the College Students Mathematical Modeling Competition. Liu Yang had the best grades besides Xu Yuan, so as the dormitory head, he naturally had high hopes for him.

I hope to win a prize so that my roommates can share in the joy and celebrate together.

"It's a pity that Brother Yuan didn't participate. If Brother Yuan and Liu Yang formed a team, they would definitely not find any rivals." Wang Haitao turned around and said confidently.

"I'm busy enough with my graduation thesis alone, so I really don't have time to join in the fun of the Higher Education Society Cup."

"Let Liu Yang complete this important task." Xu Yuan was sitting at his desk writing mathematical formulas. When he heard the conversation between the two, he temporarily stopped what he was doing and also spoke with a smile.

The school still arranged a special competition venue for the few students participating in the competition.

They ate and lived there during the competition and were not allowed to discuss the competition topics with other people outside.

But in general, time is always tight, so there is very little time to rest. Basically, I have to work hard and stay up late to ensure the successful completion of the competition modeling paper.

Therefore, Liu Yang will not return to the dormitory during the competition.

Soon Xu Yuan became interested again, stopped what he was doing and asked Li Zhenya.

"What is the topic of this year's competition?"

"I remember that undergraduates can choose one of the first two questions, right? I don't know how difficult it is." Wang Haitao also agreed curiously when he heard it.

"It seems to be the design of temporary supermarket outlets for the Olympics, and the management of transmission congestion in the power market."

"Anyway, these two questions seem difficult to me. Just thinking about them makes me feel overwhelmed."

Li Zhenya didn't hesitate at all when he heard what the two people said, and he immediately told them the titles of the two questions. It was obvious that he had checked them in advance as soon as the questions were announced at the beginning of the morning competition.

"A temporary supermarket outlet for the Olympics..."

Xu Yuan chewed on this sentence and came up with some ideas about the two questions.

I wondered if I were to participate, which question I would choose and from what angle I would complete the modeling and paper.

I have to say that the competition topics are very close to life, and are basically related to actual problems encountered.

For example, the temporary supermarket outlets for the Olympics mentioned in the first question are facilities that definitely exist.

After all, the construction work for the 2008 Yanjing Olympic Games has already entered the design and experiment stage, and similar supermarket outlets are indeed needed near the main stadium during the competition.

However, he was also aware of Liu Yang's level in mathematics, after all, he was a member of the national Olympic team.

It is not a big problem to participate in this kind of mathematical modeling competition. It should not be difficult to have an outstanding performance.

What's more, Liu Yang has been stimulated by Xu Yuan for so long, and now he has such a chance to prove himself, he will definitely try his best to seize it.

But the biggest problem is that math league competitions rely on teamwork. Sometimes, no matter how well an individual performs, it will be useless without trustworthy teammates, otherwise he will become a drag.

Thinking about this, Xu Yuan thought for a moment and said, "Liu Yang will definitely be fine. It all depends on the strength of the teammates he finds."

"After all, they are all Qinghua's students, so it shouldn't be a big deal."

"Trust Liu Yang."

Li Zhenya and Wang Haitao nodded in agreement with Xu Yuan's words, and then said nothing more.

Soon when the dormitory returned to silence, Xu Yuan was hesitating whether to go to the library to read today.

Just as I was thinking about this, my thoughts were suddenly interrupted by the ringing of my cell phone.

He reached into his trouser pocket and pulled out his cell phone, and seemed a little surprised when he saw the name on it.

"Director Liao?"

Xu Yuan didn't expect the department head to call him at this time. It was extremely unexpected.

Although he had saved the other party's phone number a long time ago, Professor Tang always contacted him when there was anything in the department. He was a little surprised when the department head Liao Fangyi called him directly today.

But this just proved that there was something special going on, so there was no more hesitation.

He quickly pressed the answer button and put the phone to his ear.

"Hello, director."

I had just said hello politely when I heard a familiar and somewhat anxious voice coming from the other end of the phone.

"Xu Yuan, where are you? Come to my place when you have time."

"I'm in the dormitory."

Xu Yuan casually told the other party his location, and then took the initiative to ask for the details.

"Director Liao, is there anything I can do for you?"

"It's not that I have something to do. It's Professor Yang from the Institute of Advanced Studies who wants to see you. Please hurry up and come over." Liao Fangyi explained patiently and then ended the call.

As Xu Yuan heard the busy tone coming from the other end of the phone, his hands seemed to be frozen in mid-air.

I am still digesting this information in my mind.

He was naturally familiar with Mr. Yang mentioned by Liao Fangyi. As another theoretical physicist after Einstein and Dirac who wrote the wonderful basic structure equation of energy, he also won various internationally renowned awards such as the Bohr Prize and the Nobel Prize in Physics.

After returning from overseas, he helped Qinghua University establish the Institute of Advanced Studies and served as its honorary dean.

And invite capable scholars and professors to join Qinghua Research Institute.

For this purpose, Qinghua University also left a master's residence that was originally built for Mr. Yang to live in.

Xu Yuan really didn't expect that such a master of physics would take the initiative to meet him, an undergraduate student, and he suddenly became excited.
