I am most afraid of the sudden silence of the air.

Yet the air was still quiet for a few seconds.

With a slightly embarrassed expression, Mr. Qiu immediately laughed twice, forcibly broke the embarrassing atmosphere, stretched out his right hand and touched his nose, and said in a confused manner.

"I almost forgot about it...... You're not the fledgling boy you were anymore. ”

Lu Zhou nodded with a smile and said politely: "It is my honor to make you feel that I have grown, which shows that I have not wasted my time in the past five or six years." ”

"Not only has it grown, but the reaction speed of my brain is almost unable to keep up with the pace of your growth," sighed softly, Mr. Qiu seemed to be caught up in the memories of the past, and his expression was slightly emotional.

After a few seconds, he diverted the topic, smiled and said, "Speaking of which, how did you think of coming to Mizuki University to go around?" ”

"You may not believe it, but I really just happened to be passing by."

After two or three sentences, Lu Zhou told Mr. Qiu about Academician Wang Shicheng's invitation. After listening to his narration, the old man pushed down the reading glasses on the bridge of his nose, frowned, and said with a somewhat unhappy expression.

"Wang Shicheng, that old thing...... Don't look at his kind eyes on the surface, I don't know what bad water is in his stomach. Don't believe a word of what he says, this bad old man is very bad, I suggest you take precautions! ”

Looking at Mr. Qiu's indignant face, Lu Zhou couldn't cry or laugh in his heart.

"I'm just going to Yanda's side, what can he do to me......"

Qiu Chengtong still told uneasily: "Anyway, that old thing is not kind!" It's nothing to go around Yanda, in short, you pay attention, don't be pitted by that old thing. ”

“…… Yes, yes, yes. ”

After all, Academician Wang Shicheng and himself have no grudges, and Lu Zhou doesn't really want to intervene in the grievances between the older generation of scholars, so he had to say yes perfunctorily and bring the topic over.

After continuing to say a few words of greeting, he said goodbye to Mr. Qiu, he turned around and walked to the west gate of Mizuki University, and walked all the way in the direction of the east gate of Yan University.

……

Yanda East Gate.

A young teacher, dressed in a crisp suit, was standing there looking around.

When he saw Lu Zhou, the young teacher recognized him from the crowd at a glance and walked up quickly with a smile on his face.

"You are Academician Lu, hello! I heard Academician Wang say that you are coming, so I will wait here. ”

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

"I stopped by Mizuki University and made you wait for a long time."

"Where, you are a world-renowned university scholar, even if I am here until tomorrow, it doesn't matter," the young professor smiled heartily and stretched out his right hand, "Yang Yongan, a professor in the Department of Mathematics, is in his early Chinese New Year's Eve, probably a little older than you, and he is ashamed to be unknown in his first year." ”

"Professor Yang is modest, and he can become a professor at Yan University in his thirties, and he is not an unknown person." Shaking Professor Yang's hand and letting go, Lu Zhou continued, "What about Academician Wang? ”

"Academician Wang is at the Mathematics Center of Yan University, because of the matter of the national training team of the IMO competition, I can't take a break for the time being, and I hope Academician Lu can understand."

IMO Contest?

That's the time for that.

"It's okay, I can understand," Lu Zhou nodded with a smile, signaling that Professor Yang didn't have to care, and after a pause, he continued, "It just so happens that I'm going to the math center too, so take me there." ”

Yang Yongan made a gesture of please.

"This way, please."

Over the years, Beijing has changed quite a lot, there are more and more new energy vehicles on the road, the buildings on both sides of the road are getting taller and higher, and there are more and more foreign friends speaking various Chinese, but only two places have not changed at all, and still retain its original style.

One is the historical and cultural relics buildings in Shangjing, and the other is the top universities in Shangjing.

It is worthy of being the top university of world civilization, just stepping on the tree-lined path near the teaching building, the strong academic atmosphere will come to the face, and every brick and tile on the eaves under your feet contains the historical and cultural heritage, and it is indeed worthy of being one of the most suitable places for academic research in China.

In fact, for Lu Zhou, whether it is the campus of Yan University or Mizuki, it is not very unfamiliar.

In the past, when he lived in a sanatorium on the edge of the Old Summer Palace, he often came here for a walk, but for various inconvenient reasons, he never went to the International Mathematical Research Center of Yan University.

It is said to be a math center located in a courtyard, with the tallest building being no more than three floors, and the most common being is the boxy blackboard.

Although the facility looks a little old, it is said that it was done on purpose. Only in the purest environment can we engage in this most primitive mental work of human beings, and the scientific research closest to the essence of the universe, which is also the original idea of the founders of this mathematical research center.

Of course, being able to live in such a spacious courtyard to conduct research in an international metropolis like Shangjing, where every inch of land is valuable, must be the envy of those mathematicians who are not in the same industry.

As soon as Lu Zhou walked into the compound, he saw a small-looking young man with glasses on the bridge of his nose in the courtyard, carrying a small bench, sitting in front of a blackboard leaning against a big banyan tree, holding half a piece of chalk in his hand, and meditating on the equation written all over the blackboard.

The gray coat had faded a little, and the hair looked like it hadn't been washed in days, but had simply been combed into a three-seven-open look, and the overly long bangs were listlessly hanging on the frames of the glasses.

Glancing at the young man who looked like a performance artist with interest, Lu Zhou asked curiously.

"Who is that?"

For some reason, when Lu Zhou set his eyes on this strange man, Yang Yongan's expression was a little subtlely embarrassed.

It's as if you've been seen to be ugly.

"Don't you care, this guy...... Mentally a little abnormal. ”

Mentally abnormal?

Lu Zhou was even more curious.

In his experience at Princeton, many people who are good at math tend to be mavericks in certain areas, so they always meet all sorts of weirdos. For example, the former editor-in-chief of a mathematical almanac never allowed anyone to sit in the office when talking to him, such as a student of his who liked mint-flavored coffee, or the old man in the flintstone library who never woke up......

Scholars like myself, who have impeccable mathematical attainments and behaviors that are no different from ordinary people, are only a minority.

"Why do you say that?"

"You know, in a place like ours, there's usually some kind of appraisal. For example, how many articles are published in the first and second districts a year, or submitted to top conferences...... But some people always like to be mavericks, and when others kindly remind them that you may be asked out because you can't pass the test, they are still looked at like fools. Yang Yongan shrugged his shoulders, "I don't think anyone else will have a good impression of him." ”

Lu Zhou asked, "Then did he come up with anything?" ”

Glancing in the direction of the man, Yang Yongan said with a little sarcasm, "If there were, he wouldn't be so miserable." ”

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

But at this look, his eyebrows suddenly raised.

“…… Hyperelliptic curve analysis? ”

Hearing this, the young man who looked like a performance artist finally had some reaction.

I saw him turn his head, push the glasses on the bridge of his nose, and say in a somewhat wooden voice.

"You understand?"

As soon as he heard this, Lu Zhou didn't have time to say anything, but Yang Yongan, who was standing next to him, almost didn't laugh out loud.

"Brother dei, you learn to be stupid, you take a closer look at who this is."

Staring at Lu Zhou for a while, the young man still had a blank expression on his face.

"Who is it?"

Professor Yang raised his eyebrows and was about to reprimand him, but he was stopped by Lu Zhou.

Not caring very much about such an inconsequential matter as not being recognized, Lu Zhou stared at the blackboard twice, and said with interest.

"Your use of hyperelliptic curve analysis is very interesting, which you don't usually use."

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

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

"I think so," Lu Zhou nodded, thought for a moment, and continued, "According to your definition of a non-singular projective complex algebraic cluster...... If I'm not mistaken, you're probably working on the Hodge conjecture? ”
