"It's a rare occurrence in a hundred years. What Senior Brother Yun said is going too far. I'm just a little more diligent and smarter than the average person."

After hearing what Senior Yun said, Zhao Xiancai also said politely.

Although Zhao Xiancai said this, if ordinary people heard what he said, they probably wouldn't think he was being modest and polite.

After all, the university where Zhao Xiancai is studying is not an ordinary university, but Peking University, the top university in the country. The most important thing on the Peking University campus is smart and hard-working people.

Zhao Xiancai said that he was more diligent and smarter than these people. In the eyes of many people, this was probably a way of showing off.

However, Yun Zhiwei obviously does not think so, because he also feels that even at Peking University, the intellectual gap between students is still quite large.

The gap is so big that even if you are a student of Peking University, you won't be able to catch up just by working hard.

"Haha, how can I be polite? What I said is all the truth.

I heard that you are going to Princeton University to study for a PhD soon? When are you planning to go?"

After Yun Zhiwei heard Zhao Xiancai's humble words, he also said with a smile, and then asked about Zhao Xiancai going to Princeton University. It seemed that everyone was more curious about this matter.

Normally, the start time for freshmen at Princeton University is almost fixed at a certain time, but due to Zhao Xiancai's special situation, he is not subject to this restriction.

"Just this month. After participating in the Morningside Mathematics Prize, I will prepare to leave for Princeton." Zhao Xiancai said.

"I have read all three of your previous papers. Although the first one is a bit different from the last two, it is still at least a doctoral level paper.

However, you have different directions for these three papers. I am curious, what research direction are you going to do after you go to Princeton University?

My current main research field is geometric representation theory. I wonder if you are interested?

If you are interested, after graduating from Princeton University, you can come to Yale University to teach. I can recommend you to the school.

However, if someone like you really wants to come to Yale, I don’t need my recommendation.

If you come to Yale, we can also talk about mathematics together. Although my main research field is geometric representation theory, I also have some understanding of other aspects.

With your achievements alone, you will definitely not have to start as a lecturer like I did."

When talking about the latter part, Yun Zhiwei smiled.

The geometric representation theory mentioned by Yun Zhiwei is to use geometric means to study representation theory issues.

Representation theory is a theory that uses concrete objects to "represent" an abstract algebraic system and maintains its basic structure to study its properties. Its central idea is to represent unfamiliar mathematics into familiar things.

"Geometric representation theory? I haven't determined my main research direction in the future yet, but when I participated in my undergraduate graduation defense at school, Dean Yang recommended that I study number theory problems.

I think it is quite good to study number theory problems. Maybe you will use some of this content when studying number theory problems later. After all, almost all branches of mathematics can be used to deal with number theory problems.

By the way, you should know the Dean Yang I just mentioned, right? He is Dean Yang Gang of our School of Mathematical Sciences."

Zhao Xiancai said.

"Yang Gang? I know this name. After all, he and Qiu... But when I was in school, he had just come to Beijing University and was not the dean of the School of Mathematics at Beijing University."

Yun Zhiwei originally wanted to talk about Yang Gang and Professor Qiu, but since Zhao Xiancai said that this Yang Gang participated in his undergraduate graduation defense and recommended him to go into number theory, it is estimated that Zhao Xiancai and this Yang Gang should have a good relationship.

Therefore, in the middle of his words, he took another turn.

"I know what happened to Dean Yang and Professor Qiu. It's all their business and has nothing to do with us. You can say whatever you want. It'll be fine."

Seeing Yun Zhiwei like this, Zhao Xiancai also said to him.

"Needless to say, it actually doesn't matter. And you're right, this is all their business and has nothing to do with us." After hearing what Zhao Xiancai said, Yun Zhiwei also smiled and said.

After that, they talked about mathematics.

…

The opening ceremony of this year's World Congress of Chinese Mathematicians was held at the Great Hall of the People, so the hotel they booked for Zhao Xiancai was also nearby. It was already afternoon when Zhao Xiancai got off the high-speed train and rushed here.

By the time he met Yun Zhiwei, it was already almost dinner time when the two started chatting.

Therefore, the two of them didn't have much time to chat today.

The day after Zhao Xiancai came here, it was time for the opening ceremony of the World Congress of Chinese Mathematicians. The opening ceremony was hosted by the Institute of Mathematics and Systems Science of the Chinese Academy of Sciences and the Morningside Mathematics Institute of the Chinese Academy of Sciences.

It was jointly organized by the Center and Shuimu University, and many big figures in domestic academic and political circles came to the event that day.

It was while attending this opening ceremony that Zhao Xiancai got to know more Chinese mathematicians.

"Are you Zhao Xiancai?"

On the morning of the opening ceremony, Zhao Xiancai and Yun Zhiwei were having breakfast together in the hotel. When they arrived at the Great Hall, a voice suddenly came from behind him.

After hearing this voice, Zhao Xiancai turned around, and only then did he realize who the person talking to him was.

The man who spoke was an old man with gray hair, the same smart hairstyle as Deligne and others, wearing a pair of reading glasses or myopia glasses, a crisp suit and a tie.

.

"Qiu Chengtong...Professor Qiu?

Yes, yes, I am Zhao Xiancai."

After seeing the old man behind him, Zhao Xiancai recognized him at a glance.

After all, when Zhao Xiancai was still in high school and participating in the national mathematics training team, he had learned more about this old man online and had seen his photos.

"Young, you are indeed young.

What I regret most now is that I didn’t persuade Shuimu to sign you.”

After receiving Zhao Xiancai's affirmative answer, Professor Qiu smiled and said to Zhao Xiancai. Although he said that this was the thing he regretted the most, judging from his expression, there was no trace of regret.

"Is this Yun Zhiwei? You have probably never met before, right?"

After Professor Qiu finished speaking to Zhao Xiancai, Yun Zhiwei was not left behind. The reason why he said this was because the age gap between Zhao Xiancai and Yun Zhiwei was too big.

Not only are there an age difference of about ten years between the two, but although Yun Zhiwei also graduated from Peking University before, Zhao Xiancai has only been in Peking University for two years, so the possibility of them getting to know each other is very slim.
