Perelman's room wasn't far from the stairs. He could see it from the side after climbing up the stairs.
"The room is a bit small, please don't mind."
Perelman placed the plastic bag on the ground and took out the keys from his pocket.
Although he was mentally prepared for the situation in the room, when he opened the door, Lu Zhou was still shocked by the situation in the room.
All kinds of clothes and daily necessities that hadn't been washed were scattered on the armrest of the sofa. All kinds of junk were piled on the ground, and there was nowhere to put them.
Lu Zhou had to admit that although he occasionally threw clothes around, he would usually clean it up himself, or Xiao Ai would clean it up for him.
But obviously …
Perelman dedicated his entire life to mathematics. Not only did he not have someone to clean up for him, but his attitude in life was also very casual.
No wonder many scholars had a weird expression on their faces when this person's name was mentioned.
Walking next to Lu Zhou, Albert, who was ridiculed by Professor Krugman as being more famous than his knowledge, whispered.
"I thought mathematicians were the kind of people who were organized."
Lu Zhou didn't know how to answer this question, so he chose to remain silent.
As for Schulz, who was standing on the other side of him, he awkwardly explained.
"Under normal circumstances, yes … but there are exceptions to everything. There are also some people who choose to be carefree in their lives and spend the time they save on more meaningful things."
"This kind of life is really enviable, but unfortunately it's not me. Ever since I embarked on the path of mathematics, most of my time has been wasted on meaningless work … "Perelman didn't care about the stranger's whisper. He put the" supplies "he purchased this week into the fridge and denied Schulz's statement. He walked back and spoke nonchalantly.
"Do you want 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. "
He really didn't want to add a burden to his life, so Lu Zhou said cautiously.
"Water is fine."
Schulz nodded in agreement. "Me too."
Seeing that Krugman and the stranger also nodded, Perelman squeezed the corner of his mouth, which was rarely seen, as if he was showing an unfamiliar smile.
"Okay, wait a moment."
Soon, five disposable cups were placed on the table. Perelman then took a 5-liter bottle of mineral water from the side and poured a cup for everyone.
Seeing that everyone was looking at him with a weird expression, he didn't care. He picked up his cup and took a sip, then looked at Schulz and went straight to the point.
"Why are you here? I never heard you were coming. "
Schulz: "Can't I visit an old friend on the way to the IMU conference?"
"I don't have anything to visit, I'm quite comfortable living alone …"
Perelman seemed to be a little disappointed by Schulz's words. After hearing that Schulz didn't come to see him with any problems, Perelman immediately lost interest in him. He then looked at Lu Zhou.
Perelman stared at him for a while and suddenly spoke in his "listless and rough" voice.
"I've read your thesis, your understanding of group theory and complex plane problems is impressive. Especially the hyperelliptic curve analysis method used to solve the Riemann conjecture … Of course, what surprised me the most was that you defined a complex algebraic cluster x on the complex projective space cp ^ when you were researching the Sullivan conjecture. I still don't understand how you came up with this. "
Topology and differential geometry were the fields that Perelman was proficient in. Compared to the quasi Riemann conjecture, problems involving differential manifolds were more interesting to him.
Especially the classification of differential manifolds. Even though this research area was unpopular, it couldn't be ignored. It could even be said to be one of the core problems in differential manifolds.
He had also researched the complex complete Sullivan conjecture, but he couldn't think of a good way to solve it, so he put it aside for the time being.
However, at the beginning of the year, he suddenly saw that Lu Zhou, who had been researching the Riemann conjecture, had published a paper in Annual Mathematics that completely solved this problem.
For a time, he was astonished to the point of questioning his life.
"… Sullivan conjecture?"
Lu Zhou paused for a second before he smiled and said, "… This is all thanks to Professor Kreck's 1999 Annual Mathematics paper, which gave me a lot of inspiration. Of course, maybe it's because I wasn't researching this problem at the time, so I was able to think about it from an angle that most people wouldn't think of. "
At the time, he was answering Chen Yang's question about the Hodge conjecture. If it weren't for the editor-in-chief of Annual Mathematics, he wouldn't have known that he was researching a very famous representation of the differential manifold classification problem.
However, when Perelman and Schulz heard that Lu Zhou wasn't actually researching the differential manifold classification problem, they were both surprised.
Fortunately, they didn't know that Lu Zhou spent an entire day coming up with this problem. Otherwise, their jaws would have dropped to the ground.
Perelman took a sip of cold water and spoke.
"Enviable luck, but I don't think this can be explained by luck … So, back to the topic, do you have any problems you want to discuss with me?"
Lu Zhou saw the look of anticipation in Lu Zhou's eyes, and he suddenly felt a little embarrassed.
Actually, Lu Zhou was just like Schulz, maybe even more bored. After all, the latter was here to visit an old friend, and he was purely here to satisfy his curiosity about this hermit, which was no different from visiting a place like the Winter Palace.
However, it was a bit rude to say it out loud.
After all, he wasn't a gorilla in the zoo. Judging from this guy's attitude of not wanting to talk nonsense about unimportant things, he obviously wasn't the kind of person who liked to socialize.
What should I do?
Tell the truth?
However, Lu Zhou was a little worried that if he told the truth, Lu Zhou would block him.
Suddenly, a light bulb went off in his head. He remembered a few problems that he discussed with Chen Yang about the Hodge conjecture at the Jinling Institute for Advanced Study.
"Can I borrow a piece of paper?"
"Sure, there's a lot here."
Soon after, Perelman pulled out a dirty notebook and a ballpoint pen from the sofa next to him. He handed them to Lu Zhou.
Lu Zhou took the paper money and wrote down his questions in the notebook. He then handed it to Perelman.
"… That's it."
"… Let me see," said Perelman. He took the notebook and quickly glanced at the equations on it. He looked surprised and said, "You're researching the Hodge conjecture?"
Lu Zhou bit the bullet and said, "Sort of."
Actually, it wasn't a lie. Even though he didn't actually research this conjecture, there were still people in his research institute who were researching this conjecture.
However, Perelman seemed to believe it. He nodded and muttered, "No wonder, so you're researching the Hodge conjecture.
After reading your thesis, I felt like the method mentioned in it could be used to solve this type of problem … " After reading your paper, I feel that the method mentioned in it can be used to solve this kind of problem … "
"… When did you start researching the Hodge conjecture?"
"… When did you start researching the Hodge conjecture?"
"When I'm not busy."
Schulz: "…"
Schultz: "…"
It was like he had forgotten about the guests sitting here. He was completely immersed in his own world. Time quickly passed by. Albert got up and looked at the notebook. However, he was quickly defeated by the lines of equations. He sat back down with a headache.
Albert couldn't sit still any longer. He got up and took a look at the notebook, but he was quickly defeated by the lines of calculations. He sat back down with a headache.
As for Krugman, who was sitting next to him, he didn't move at all. He just calmly drank his tea.
Lu Zhou looked at the Russian, who was deep in thought, and spoke with a guilty conscience.
"… Actually, you don't have to give me an answer immediately. You can just send me an email later."
"… You're right, this problem can't be explained in a few words." Perelman agreed with Lu Zhou. He put away his notebook and looked at Professor Krugman and Albert. "What about you guys? Tell me if you have any questions. "
Krugman took a deep breath and finally found a chance to speak. He cleared his throat and said solemnly, "We're here for a significant research project. It involves a lot of complex mathematical calculations, which are beyond our ability —"
However, as soon 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 these words came out of his mouth.
The entire apartment, which was less than 20 square meters in size, instantly fell silent …
