Rewrite the Technological Landscape

Meng Qian walked onto the stage in the eyes of everyone, and bowed to everyone after he took the stage, "I'm sorry, I need to write something on the blackboard, so I take the liberty to go on stage."

Having said that, in fact, it means being polite. It is a free discussion. Anyone who has an idea can come to the stage and no one will stop him.

Meng Qian bowed to Grigory Perelman after being polite to everyone, "Mr. Perelman, there are always some self-righteous juniors who want to challenge the seniors in order to gain the attention of people in the industry, Perel Don't take it to heart, Mr. Man."

Maregni couldn't help feeling angry when he heard the words, but he didn't know what to say.

Meng Qian continued, "I have read Mr. Perelman's research since I was a child, and I have my own views on the Poincaré conjecture, so I would like to take this opportunity to ask Mr. Perelman for advice."

Grigory Perelman nodded.

Then Meng Qian went to the blackboard, "Since Maregni mentioned the importance of topology in the proof of the Poincaré conjecture, how can I make modifications at the singularity and finally converge without changing the topology?" Let's start with a simple calculation in terms of angles measured by constant curvature.

As for Hamilton's research and Rich flow, Mr. Perelman has said very clearly just now, let's look at it directly from the non-collapse theorem. "

After all, everyone was speaking English on this occasion, and it was not at Huaxia's home court. Meng Qian wrote in English on the blackboard:

"let k, r be two positive constants and let gij(t), 0\u003c=t

|Rm|(x,t)\u003c=r-2.

"

"Next, let's study singularity generation through the Ricci flow:

Suppose we hace a complete gradient steady ricci soliton gij with bounded curvature so that”

"Let's take another look at the long-term behavioral model of the Rich flow:

Recall that a solutiongij(t) to the ricci flow is said to be a gradienr shrinking ricci soliton if there exists a smooth function f such thct”

"Now we can look at the three-dimensional properties of the Ridge flow"

With the continuation of Meng Qian's proof process, everyone's attention has been completely attracted by Meng Qian, especially Grigory Perelman.

Because Meng Qian's whole idea of ​​proof is almost exactly the same as his.

Even, it seems to be more detailed than him.

After all, what Meng Qian plagiarized was his paper, and the optimized version based on his paper after 2011

Meng Qian does not have a rebirth memory hang, so he cannot fully remember the entire proof process of the Poincaré conjecture.

What he can remember is some core things, because the Poincaré conjecture is not like the ABC conjecture. Only 12 people in the world can understand the paper written by Mochizuki Shinichi, and these 12 people don’t know how to make others understand it, so Although Meng Qian's later generations have also read Mochizuki Shinichi's thesis, the ending is naturally incomprehensible.

But the Poincaré conjecture is different. Many people can understand it, and many people explain it and popularize it. Meng Qian was admitted to Jiangda University by himself, and he is really talented in mathematics, so he When I went to study the Poincaré conjecture, I absorbed a lot.

Although he is really asked to write out the entire proof process now, he will definitely not be able to write it out, although he will definitely not be able to explain the core proof process clearly, but on this occasion, only the most important points It would be more appropriate to write it out, because if the whole proof is really written out, wouldn’t that mean that the proof of the Poincaré conjecture is completely disclosed.

Therefore, Meng Qian's lack of ability, but in the eyes of outsiders, it is a point-to-point proof process is just right.

Behind this point so far, the association of normal people is not that Meng Qian is not deep enough, but that Meng Qian does not want to tell the whole story.

"How did Meng Qian have such a deep understanding of geometry?" When Meng Qian finished his semi-in-depth proof process, Yun Wei couldn't sit still, and he hurriedly asked Zhuo Liangcai.

"I don't know either." Zhuo Liang spread his hands together, he also looked confused, he couldn't even understand, "I only know that Meng Qian was from the mathematics department of our school before, and he seems to have a perfect score in mathematics in the college entrance examination? I I can’t remember clearly either. He suddenly transferred to our computer department this year.”

"His talent in mathematics is so high, why did he transfer to the computer department?" Yun Wei couldn't help asking.

"As far as I know, he is here for artificial intelligence." Jiang University's computer department has three major research directions, one of which is artificial intelligence.

Zhuo Liangcai's explanation has also been accepted by everyone. After all, artificial intelligence does require mathematical skills.

On the other side, after Meng Qian finished his speech on the stage, he looked at Grigory Perelman again, "Mr. Perelman, a little opinion of the students, I would like to ask Mr. Perelman for advice." One or two."

The way Grigory Perelman looked at Meng Qian had completely changed, and everyone's eyes were also focused on Grigory Perelman, wanting to see what he would say.

After a long silence, Grigory Perelman finally spoke, "When is Mr. Meng free, I will visit Mr. Meng."

"Hiss~~" The audience was shocked, Grigory Perelman's visit was more important than any verbal affirmation, which was equivalent to telling everyone at the scene that Grigory Perelman Man very much agrees with Meng Qian's idea.

"As long as Mr. Perelman speaks, the students are free at any time." After Meng Qian responded, Grigory Perelman simply nodded again, and did not intend to continue.

This is the character of Grigory Perelman. Meng Qian and everyone present knew it, so naturally they would not ask him what he meant.

Meng Qian turned his gaze to the other side, "Male Gobi, do you understand?"

Many people noticed that Meng Qian called the wrong name, but it was just that the pronunciation of the Huaxia people was not standard, and only the Huaxia people present were trying to hold back their laughter.

Maregni's face turned red, but he still couldn't swallow his breath, "To put it bluntly, it's not that topology can't solve the Poincaré conjecture. I still say that, this is not the mainstream!"

"I haven't heard of any saying that there is no mainstream in the mathematics world. The mathematics circle always only recognizes the results." At this moment, another person suddenly spoke.

Like everyone else in the audience, Meng Qian looked curiously at the person who spoke, and the person who spoke was Tao Zhexuan.

Tao Zhexuan was looking at Meng Qian at the moment, the two eyes met, Meng Qian smiled and nodded, Tao Zhexuan also nodded slightly.

With the approval of Grigory Perelman and the obvious support of Tao Zhexuan, Maregni wanted to speak but couldn't.

But at this time, Tao Zhexuan asked a question as if he was helping Maregni, "Meng Qian, I'm actually curious, why do you put the solution to the Poincaré conjecture in the differential equation?" Geometrically."

Meng Qian smiled calmly, "Do you think there is a smooth four-dimensional space, which is homeomorphic to a four-dimensional sphere but not diffeomorphic?"

"I understand." Tao Zhexuan smiled and stopped talking.

After Tao Zhexuan, several people naturally raised their own questions. Meng Qian answered what he could answer, and practiced Tai Chi when he couldn't answer. After all, what he said just now was deep enough. At this time, many people asked more in-depth questions. Meng Qian showed an attitude that it was inconvenient to continue talking.

Everyone can accept it. Although some people have some doubts, it is impossible to question Meng Qian now. After all, what Meng Qian just said is real dry stuff.

After all the people who should ask questions have finished asking, those who need to contact in private will also contact in private, and everyone is preparing for Meng Qian to step down, but at this time, Meng Qian suddenly said, "Since we talked about the Poincaré conjecture, today Many people have mentioned Goldbach's conjecture, and I would like to take this opportunity to share my thoughts, is it convenient?"

Everyone was startled and looked at Meng Qian with complicated eyes.
