Chapter 1008

Perelman's room is not far from the stairs, and you can see it when you go up the stairs.

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

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

Although he was prepared for the situation in the house, after he opened the door, the boat was still shocked by the situation in the house.

All kinds of clothes and daily necessities that haven't been cleaned yet are so disorderly on the armrest of the sofa. All kinds of sundries piled on the ground make people look at the place where they can't see their feet.

Lu Zhou admits that although he occasionally does things like throwing clothes around, generally speaking, either he remembers to clean up, or Xiao AI cleans up for him cleverly.

But obviously.

Perelman, who devoted all his life to mathematics, not only had no one to clean his clothes, but also had a casual attitude in life.

It's no wonder that many scholars he knows have strange expressions on their faces when mentioning this person's name.

Walking beside the boat, Albert, the physicist who was ridiculed by Professor Krugman as a novel more famous than learning, whispered.

"I thought mathematicians were all well-organized people."

I don't know how to answer this question. The boat chose silence.

As for Schulz on his other side, it was an awkward explanation.

"Usually But there are exceptions to everything. There are also some people who choose to live their lives in an informal way and spend the time they save on more meaningful things. "

"I really envy this kind of life, but it's not me. Since I took the path of mathematics, most of my time has been wasted by me on meaningless useless work... " Ignoring the stranger's whisper, Perelman, who put the "supplies" purchased this week into the refrigerator, denied Schulz's excuse, and walked back to continue without incident.

"Would you like something to drink? Although there is 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 to his life," Lu said modestly.

"Water will do."

Schulz nodded, "me too."

See Krugman and that stranger also nodded, Perelman's mouth corner rarely squeezed, like a strange smile.

"OK, just a moment."

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

Seeing several people looking at themselves strangely, he didn't care. He took a drink from his cup, then turned his eyes to Schulz, and the topic directly came to the point.

"Why are you here? I haven't heard of you coming at all. "

Schultz: "on the way to the IMU conference, can't you visit your old friends?"

"I don't have much to visit. I'm very comfortable alone..."

After hearing that Schulz didn't come to find himself with any problems, Perelman lost interest in him immediately, and then his eyes soon fell on the land boat.

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

"I've read your paper. Your understanding of group theory and complex plane problems is impressive. Especially in solving the Riemann conjecture, the hyperelliptic curve analysis method Of course, what surprises me most is that you defined a complex completely intersecting complex algebraic cluster x on the complex projective space CP ＾ (n + R) when you studied Sullivan's conjecture. I still don't know how you think so far. "

Topology and differential geometry are the fields that Perelman is proficient in. Compared with the quasi Riemannian conjecture, the problems involving differential manifolds are more interesting to him.

In particular, the classification of Differential Manifolds, although the research direction is not popular, but unexpectedly it can not be ignored, or even can be said to be one of the core problems of differential manifolds.

Mr. Sullivan, who is fully engaged in the research, guessed that he had also done so, but for a while he didn't come up with any good methods, so he put them aside.

As a result, at the beginning of the year, when he almost forgot about it, he suddenly saw that the paper published in the annals of mathematics by Lu Zhou, who had been studying Riemann's conjecture, had completely solved the problem.

At one time, it surprised him to doubt life.

“…… Sullivan conjecture? "

Lu Zhou was a little stupefied, and then he responded with a smile and said, " Thanks to Professor Crake's paper published in the annals of mathematics in 1999, it has brought me a lot of inspiration. Of course, it's also possible that I didn't study this problem at that time, so I was able to think from an angle that ordinary people wouldn't think of. "At that time, he was answering Chen Yang's questions about the study of Hodge's conjecture. If he hadn't been reminded by the editor in chief of the mathematical Yearbook, he didn't even know that what he was studying was another manifestation of a famous important proposition in differential manifold classification.

However, Perelman and Schulz were surprised when they heard that the land boat was not really studying the classification of differential manifold.

Fortunately, they didn't know that Lu Zhouhua had spent a whole day thinking about this problem, otherwise he was afraid that his chin would fall to the ground.

Put away the surprised sight, 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, to put it straight, do you have any questions you want to discuss with me? "

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

In fact, he is as boring as Schulz. After all, the latter came to visit his old friends, and he just came to satisfy his curiosity about the hermit with the same idea as visiting the winter palace.

However, it's still a bit rude to say that directly.

After all, they are not gorillas in the zoo. Judging from his attitude that he doesn't want to talk nonsense about unimportant matters, he is obviously not that kind of social person.

What to do?

To be honest?

But Lu Zhou was a little worried about whether he would be blackmailed by this guy if he told the truth.

At this time, his mind suddenly flashed, and he remembered several problems he had discussed with Chen Yang in the discussion of Hodge's conjecture in Jinling Institute of higher learning some time ago.

"May I borrow a piece of paper?"

"Yes, there are many."

Soon, Perelman turned out a dirty notebook and a ball point pen without a pen cover from the sofa beside him and handed them to the boat.

After taking the note, under the eyes of several people, Lu Zhou wrote down his questions in his notebook and handed them to Perelman.

“…… That's it. "

“…… Let me see, "after taking over the notebook, Perelman quickly glanced at the above formula, with a touch of surprise in his eyes," are you studying Hodge's conjecture? "

The boat said, "that's right."

In fact, it's not a lie. Although he didn't really enter into the study of this problem, there are still some people in his research institute who are studying it, and they often discuss it with him.

Perelman, however, seemed to believe it, and with a certain nod, murmured.

"No wonder I was studying Hodge's conjecture. I said that after reading your paper, it seems that the methods mentioned in it can be used to solve such problems... "

Schulz was surprised, and looked at the boat strangely.

“…… When did you study Hodge's conjecture? "

Lu Zhou is embarrassed to smile.

"When not busy."

Schulz: "..."

Time went by, and Perelman didn't respond at all. It's like forgetting a few guests sitting here, completely immersed in their own world.

Some couldn't sit down. Albert got up and looked closely at his notebook, but was soon defeated by the line of ghost like calculations, and sat back with a headache on his face.

As for Krugman, who was sitting next to him, who had expected that he would not understand, he did not move at all and drank water calmly.

Looking at the Russian who was in deep meditation, the boat said with a little heart.

“…… In fact, you don't have to give me a reply immediately. It's the same with emailing me afterwards. "

“…… What's more, it's not like that the question can be explained clearly in three words. "He agreed with Lu Zhou's statement. After whispering, Perelman put away his notebook, and then continued to look at Professor Krugman and Albert." what about you? Let me know if you have any questions. "

Krugman took a deep breath. After half a day's gestation, he finally found the opportunity to speak. After clearing his throat, he said solemnly, "we are here for a significant research topic, which involves many complex mathematical calculations, which are beyond our ability."

however, his speech, which has been brewing for half a day, has just begun He was interrupted by Albert sitting next to him.

I saw the physicist stand up and speak to the crowd in an excited / emotional voice.

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

It was almost at the same time that the sentence came out.

In the whole single apartment less than 20 square meters, it was quiet for a moment
