Most afraid of the air suddenly quiet.

But the air was still quiet for a few seconds.

The expression is a little embarrassed. Mr. Qiu laughs twice, breaks the awkward atmosphere, reaches out his right hand to touch his nose, and says in a confused way.

"I almost forgot about it You're not the first young man. "

Lu Zhou nodded with a smile and said politely, "it's my honor to let you feel that I have grown up. It shows that I haven't wasted five or six years."

"More than growing up, I can't keep up with the pace of your growth." with a slight sigh, Mr. Qiu seemed to be trapped in memories of the past, with a little emotion on his face.

After a few seconds or so, he turned off the topic, smiled and said, "say, how do you think of coming to Shuimu university?"

"You may not believe it. I just happened to pass by."

After two or three sentences, Lu Zhou gave the invitation of Academician Wang Shicheng to Mr. Qiu. After listening to his narration, the old man pushed the presbyopic glasses on the bridge of his nose, frowned, and said with some displeasure.

"Wang Shicheng, the old man Don't look at his good purpose, I don't know what bad water is in his stomach. Don't believe a word he said. It's a bad old man. I suggest you guard against it! "

Looking at Mr. Qiu's angry face, Lu Zhou's heart was filled with tears.

"I'm going to visit Yanda. What can he do to me..."

Qiu Chengtong is still uneasy and admonishes: "anyway, the old man is not kind! There's nothing wrong with going to Yanda. In a word, you should pay attention to it. Don't be trapped by that old thing. "

“…… Yes, yes. "

After all, Academician Wang Shicheng has no hatred or resentment with himself, and Lu Zhou does not want to get involved in the resentment between the older generation of scholars, so he has to perfunctorily say yes and take this topic to the past.

After a few more greetings, he left Mr. Qiu and turned to the west gate of Shuimu University. He walked all the way to the east gate of Yanda.

……

Yanda east gate.

A young teacher in a stiff suit is standing there looking around.

When he saw the boat, the young teacher recognized him from the crowd at a glance, and quickly stepped up with a smile.

"You are academician Lu, how do you do! I heard Academician Wang say you are coming, and I will wait here. "

Looking at the enthusiastic young teacher, Lu Zhou nodded with a smile.

"I took a turn at Shuimu University along the way, which made you wait a long time."

"No matter where you are, you are a world-renowned university, even if you let me stay here until tomorrow," said the young professor with a bright smile and a right hand. "Yang Yong'an, a professor of mathematics, is in his early thirties, maybe a little older than you. I'm very ashamed that he has been silent since his establishment."

"Professor Yang is modest. It's not unknown that he can become a professor of Yanda in his thirties." He shook Professor Yang's hand and let it go. Lu Zhou continued, "what about Academician Wang?"

"Academician Wang is at Yanda mathematics center, because the national training team of IMO competition can't be separated for the time being, and I hope academician Lu can understand."

IMO competition?

It's time to say that.

"It's OK, I can understand it," Lu Zhou said with a smile, indicating that Professor Yang didn't care. After a pause, he continued, "it happens that I'm going to the math center, so I'll take me there."

Yang Yong'an made a gesture of invitation.

"This way, please."

In recent years, the changes in Beijing have been quite big. There are more and more new energy vehicles on the road, the buildings on both sides of the road are higher and higher, and more and more foreign friends speak different languages. However, the only two places have not changed at all, and they still retain their original features.

One is the historic buildings in Shangjing, and the other is the top universities in Shangjing.

It is worthy of being one of the world's top institutions of learning. Just after stepping on the Boulevard near the teaching building, the strong academic atmosphere comes to our face. The bricks and tiles on the eaves at the foot contain the historical and cultural details. It is indeed one of the most suitable places for academic research in China.

In fact, for the land boat, neither Yanda nor Shuimu campus is very strange.

He used to come here for a walk when he lived in the sanatorium next to the Yuanmingyuan. For various inconvenient reasons, he didn't go to the International Mathematics Research Center of Yanda.

It is said that it is a math center located in the courtyard. The highest building is only three floors, and the most common one is the square blackboard.

Although the facilities look old, they are said to have been made on purpose. Only in the purest environment can we engage in the most primitive human brain work and the scientific research closest to the nature of the universe, which is the original idea of the founder of the mathematical research center.Of course, being able to do research in such a spacious quadrangle in Shangjing, an international metropolis full of land and money, must be a thing that the mathematicians envy.

When Lu zhougang walked into the courtyard, he saw a young man with glasses on his nose carrying a small bench, sitting in front of a blackboard next to the big banyan tree, holding half of the chalk in his hand, thinking bitterly about the formula filled with blackboards.

The grey coat had been washed a little faded, and the hair looked like it had not been washed in some days, but it was simply combed into the shape of three or seven open, and the long bangs hung listlessly on the eyeglass frame.

Looking at the young man like a behavior artist with interest, Lu Zhou asked curiously.

"That is?"

Somehow, when Lu Zhou's eyes fell on the strange man, Yang Yong'an's expression was slightly embarrassed.

It's like being seen something ugly.

"Don't worry, this guy There's something wrong with the spirit. "

Mentally abnormal?

On the contrary, Lu Zhou is more curious.

According to his experience in Princeton, many of the people who are good at mathematics are somewhat maverick in some fields, so they can always meet all kinds of weirdos. For example, the former editor of a math Yearbook never allows others to sit when talking with him in the office, for example, one of his students likes Mint Coffee, for example, the old man who always does not wake up in the flint Library

Scholars like myself, who are impeccable in mathematics and have no different behavior from ordinary people, are only a few.

"Why do you say that?"

"You know, in places like ours, there are usually some indicators. For example, how many articles are distributed in one area and two areas in a year, or contributions are submitted at top-level meetings But some people always like to be independent, and when others kindly remind him that you may be invited out because you can't pass the examination if you go on like this, you will be looked at with the eyes of a fool. " Yang Yong'an shrugged. "I don't think anyone would like to have a good opinion of him."

Lu Zhou asked, "did he work out anything?"

Looking in the direction of the man, Yang Yongan said sarcastically, "if there were, he would not have been so miserable."

Out of curiosity, Lu Zhou ignored Professor Yang's advice and stepped forward to have a look.

But this time, his eyebrows suddenly picked.

“…… Hyperelliptic curve analysis method? "

Hearing this, the young man who looked like a behavioral artist finally had some reactions.

He turned around, pushed his glasses on the bridge of his nose, and said in a dull voice.

"Do you understand?"

Hearing this, Lu Zhou didn't have time to say anything, but Yang Yong'an, who was standing beside him, almost didn't laugh.

"Brother Dei, you're stupid. Take a closer look at who this is."

After staring at the boat for a while, the young man was still in a daze.

"Who is it?"

Professor Yang raised his eyebrows and was about to scold him, but he was stopped by a boat.

He didn't really care about the unimportant things he didn't recognize. Lu Zhou stared at the blackboard and said with interest.

"Your use of hyperelliptic curve analysis is very interesting. Generally speaking, people don't use it."

The young man pushed his glasses and continued to look at the blackboard.

"After all, I'm not studying Riemann's conjecture This method was originally designed for Riemann conjecture. "

"I think so," Lu Zhou nodded, pondered for a moment, then continued, "according to your definition of nonsingular projective complex algebraic cluster If I'm not wrong, what you're studying is probably Hodge's guess? "
