Chapter 1009 Predict the Future?

Perelman's room was not far from the stairs, and he could see it when he turned sideways after climbing the stairs.

"The room is a bit small, please don't mind."

After dropping these words, Perelman put the plastic bag in his right hand on the ground, and took out the key from his pocket.

Although he was mentally prepared for the situation in the room, after he opened the door, Lu Zhou was still taken aback by the situation in the room.

All kinds of clothes and daily necessities that haven't had time to be cleaned are so messy on the armrest of the sofa, and all kinds of sundries piled on the ground make people look around and see no place to stay.

Lu Zhou admitted that although he would occasionally do things like throwing clothes, generally speaking, he either thought of cleaning up by himself, or Xiao Ai would clean up for him obediently.

But obviously.

Perelman, who devotes all his life to mathematics, not only has no one who can pack his clothes for him, but also has a casual attitude in life.

No wonder many of the scholars he knew had weird expressions on their faces when they mentioned this man's name.

Walking beside Lu Zhou, the physicist Albert, who was ridiculed by Professor Krugman as being more famous for novels than learning, muttered in a low voice.

"I thought mathematicians were the orderly kind."

Not knowing how to answer this question, Lu Zhou chose to remain silent.

As for Schultz, who was standing on the other side of him, he explained embarrassingly.

"Generally yes... but there are exceptions to everything, and there are some people who choose to live their lives loose and spend the time they save on more meaningful things."

"I really envy this kind of life, but it's a pity that it's not me. Since I took the path of mathematics, I have wasted most of my time on meaningless and useless work..." I didn't care about the stranger's treatment of me. Talking in a low voice, Perelman, who put the "supply" purchased this week into the refrigerator, denied Schultz's excuse, walked back, and continued talking nonchalantly.

"Do you want something to drink? Although there are only water and tea here, if you want to drink something else, I can go out and buy it."

I really don't want to add burden to his life, Lu Zhou said cautiously.

"Water will do."

Schultz nodded in agreement: "Me too."

Seeing that Krugman and the stranger also nodded, the corners of Perelman's mouth were rarely squeezed, as if showing a strange smile.

"OK, wait."

Soon, five disposable cups were placed on the table, and Perelman then took a 5-liter large bucket of mineral water from the side and poured a cup for each person.

Seeing a few people looking at him with weird expressions, he didn't care, picked up his cup and took a sip, then turned his gaze to Schultz, and the topic went straight to the point.

"Why are you here? I never heard that you were coming."

Schultz: "Isn't it okay to visit old friends on the way to the IMU conference?"

"I don't have anything to visit, I'm quite comfortable living alone..."

He seemed a little disappointed by Schultz's statement. After hearing that he didn't come to him with any questions, Perelman immediately lost interest in him, and then his eyes quickly fell on Lu Zhou.

Staring at him up and down for a while, Perelman suddenly muttered in his characteristic "slouched but rough" voice.

"I have read your papers, and your understanding of group theory and complex plane problems is impressive. Especially the hyperelliptic curve analysis method used when solving the Riemann Hypothesis...Of course, what surprised me the most is When you were studying Sullivan’s conjecture, you defined a complex fully intersecting complex algebraic variety X on the complex projective space CP＾(n+r), and I still haven’t figured out how you came up with it.”

Topology and differential geometry are the fields that Perelman is proficient in. Compared with the quasi-Riemann conjecture, problems involving differential manifolds can arouse his interest more.

Especially the classification of differential manifolds. Although this research direction is unpopular, it is unexpectedly impossible to ignore. It can even be said to be one of the core issues of differential manifolds.

Sullivan, who had completed the handover, guessed that he had also studied it, but he didn't think of any good method for a while, so he put it aside for the time being.

As a result, just when he almost forgot about it, at the beginning of the year, he suddenly saw a paper published by Lu Zhou, who had been studying the Riemann conjecture, in the "Annals of Mathematics", which completely solved this problem.

This once made him so surprised that he doubted his life.

"...Sullivan guess?"

Lu Zhou was stunned for a moment, then reacted, smiled and said, "...This is thanks to the paper published by Professor Craik on the "Annals of Mathematics" in 1999, which brought a lot to my research. Of course, it may also be because I was not researching this problem at the time, so I was able to think from an angle that ordinary people would not think of.”

At that time, he was answering Chen Yang's question about the problems encountered in the study of Hodge's conjecture. If it hadn't been for the reminder from the editor-in-chief of "Annals of Mathematics", he would not even know that what he was studying turned out to be a problem in the classification of differential manifolds. Another representation of the well-known grand proposition.

However, when they heard that Lu Zhou was not actually studying the classification of differential manifolds, Perelman and Schultz both had surprised expressions on their faces.

Fortunately, they didn't know that Lu Zhou had spent a whole day thinking about this question, otherwise his jaw would have dropped to the ground.

Putting away his surprised gaze, Perelman took a sip of cold water and continued to ask.

"Enviable luck, although I don't think it can be explained by luck... So let's get down to business, do you have any problems you want to discuss with me here?"

Seeing the imperceptible anticipation in his eyes, Lu Zhou instantly felt a little embarrassed.

In fact, he is as boring as Schultz, if not more boring than the latter. After all, the latter came to visit an old friend anyway, and he ran over to satisfy his curiosity about the hermit purely with the idea that it was no different from visiting a place like the Winter Palace.

However, it still feels a little too rude to say it directly.

After all, he's not a gorilla in a zoo, and judging from his attitude of not wanting to talk nonsense about unimportant things, he's obviously not the kind of person who likes to socialize.

What to do?

be honest?

But Lu Zhou was a little worried, if he really told the truth, would he be blocked by this guy.

At this moment, a flash of inspiration suddenly flashed in his mind, and he remembered some issues that he and Chen Yang discussed about Hodge's conjecture at the Jinling Institute for Advanced Study some time ago.

"Can I borrow a piece of paper?"

"Okay, there are a lot here."

Soon, Perelman found a dirty notebook and a ballpoint pen with a missing cap from the sofa next to it, and handed them to Lu Zhou.

After receiving the banknotes, under the curious eyes of several people, Lu Zhou wrote down his question in the notebook, and then handed it to Perelman.

"...That's all."

"...Let me see." After taking the notebook, Perelman quickly glanced at the calculation formula on it, with a hint of surprise in his eyes, "Are you studying Hodge's conjecture?"

Lu Zhou bit the bullet and said, "That's right."

In fact, it is not a lie. Although he has not really entered into the research of this issue, there are still people in his research institute who are researching, and often discuss such issues with him.

However, Perelman seemed to believe it, and nodded as if he really did, muttering.

"No wonder, it turns out that I was studying Hodge's conjecture. I said that after reading your paper, I feel that the method mentioned in it seems to be used to solve this type of problem..."

Schultz had a surprised expression on his face, and gave Lu Zhou a weird look.

"...When did you study Hodge's conjecture?"

Lu Zhou smiled embarrassedly.

"When not busy."

Schultz: "..."

Time passed by, and Perelman stared at the question for more than ten minutes, but Perelman didn't respond at all. It's like a few guests who forgot to sit here, completely immersed in their own world.

Some couldn't sit still, and Albert stood up and took a look at the notebook, but was soon defeated by the lines of calculations that looked like ghosts and symbols, and sat back with a headache on his face.

As for Krugman sitting next to him, he had already predicted that he would not be able to understand, but he didn't move at all, drinking water there calmly.

Looking at the Russian who was deep in thought, Lu Zhou said with a guilty conscience.

"...Actually, you don't have to give me an answer right away, it's the same if you email me afterwards."

"...That's right, this question doesn't seem to be something that can be explained clearly in a few words," Perelman agreed with Lu Zhou's statement, and after muttering, he put away his notebook, and then continued to look at the Professor Krugman and Albert, "What about you? Let me know if you have any questions."

Krugman took a deep breath. He had been brewing for a long time and finally found a chance to speak. After clearing his throat, he said solemnly: "We are here for a significant research topic, which involves many Complicated mathematical calculations are beyond our ability—”

However, just as he spoke, he was interrupted by Albert who was sitting next to him.

The physicist stood up and spoke to the crowd in a passionate voice.

"Gentlemen, do you believe that our future can be predicted?"

Almost at the same time as this sentence came out.

In the single apartment of less than 20 square meters, there was an instant silence...
