Scholar’s Advanced Technological System

Lu Zhou, who is sufficiently authoritative in the field of partial differential equations, wants to go, and only Qiu Chengtong is the old mister.

Regarding the achievements of Qiu Lao mister in differential geometry, there is no need to say much.

Turning on the preface to the “Differential Geometry Handout”, you can see such a sentence – “He is the founder of the geometric analysis school.”

What is geometric analysis?

It is the method of partial differentiation that moves into the differential geometry.

Although the domestic academic community has a mixed reputation for its sharp contradiction with Yanda, the international academic community’s evaluation of the Chinese Scholar is still quite high.

And this can be seen from the honors he has obtained.

At the same time, Field’s Medal, Wolf Prize, and Clayford Awards have three world-class awards in the history of mathematics. One of them is Lu Zhou’s mentor Pierre Deligne and the other is Qiu Chengtong.

At the time of the award of the Mathematical Awards in Chen, Lu Zhou and Qiu Lao Mister had a relationship, and since there were not many intersections because of the different research directions.

The NS equation is a problem in the field of partial differential equations. For the field of partial differential equations, there is no doubt that Qiu Lao’s achievements and knowledge are the highest in the scholars Lu Zhou knows.

In the city of Cambridge, Massachusetts, a stupid Ford explorer, parked near the building of the Mathematics Department.

After getting out of the car, Lu Zhou looked around and didn’t know how the next road went.

So he instinctively stopped and asked a passerby who looked like he was studying mathematics.

“fellow student Hello, may I ask, how is the office of Qiu Professor going?”

“You look for Qiu Professor?” The boy with glasses looked at Lu Zhou with a puzzled look. He always felt that this person looked at the face and looked at it, but he couldn’t remember where he had seen it, so he asked. “What are you looking for in Qiu Professor?”

Lu Zhou: “Some questions I would like to ask.”

Maybe it’s too young to see him. It’s not like you can ask any clever question. After the glasses man hears this sentence, faintly smiled: “Qiu Professor can’t give you answers to simple questions. What’s wrong with you? Ask me.”

With a slight sigh, Lu Zhou immediately laughed, “Is it? Then you can answer for me, is there a non-trivial backward self-similar solution for the Navier-Stokes equation?”

At the moment of hearing the problem, the glasses man was even stunned.

However, he did not want to admit that he could not think of it. He began to think about it. However, frowns pondered for a long time and did not figure out how to answer this question.

It can be seen that the partial differential equation should be his specialty, and he also knows about the Navier-Stokes equation.

However, it is also obvious that he did not go deep enough into his major, or that the research direction is not on it.

Otherwise, it is not difficult to know that he has studied the Navier-Stokes equation. This problem was actually answered by three mathematics homes such as Necas in 1995.

Lu Zhou looked at the table below and said casually: “Can you take me now?”

“Yes, brother, you are asking me,” the glasses man smiled, barely nodded and said, “… Come with me, but Qiu old mister is a busy man, I can’t guarantee that he will see you. “”

Lu Zhou laughed, didn’t say anything, followed him behind.

Talking on the road, Lu Zhou learned that this man’s name is Zhao D, graduated from Shuimu, and is currently studying at the Harvard Mathematics Department, reading at the good friend of the old Mister, Steve Nadis. Direct blog.

“You are the freshman of the undergraduate department?”

Lu Zhou did not deny, but asked: “Why do you say that?”

Zhao D grinned: “Because your hair looks quite a lot, it looks younger.”

Lu Zhou: …?

This……

Is it a reason?

Didn’t stop here, Zhao D continued to talk and said: “…you have to see the question from which reference book, but I suggest that you should concentrate on the research of these frontier areas. In the knowledge of this profession, it is more important to lay a solid foundation and study the contents of those super-classes than aiming too high.”

This man is very interesting, his heart is not bad, it is too warm.

If you become a Professor in the future, you will be loved by the diligent students.

Lu Zhou laughed: “It makes sense and is taught.”

Seeing this “Junior Brother” is so taught, Zhao D is happy in his heart, and he smiles heartily and said generously: “When you go out, everyone is a compatriot, and it is appropriate to help each other. If you don’t understand anything, you can come and find it.” I, call me Zhao brother, or four fire brothers!”

Lu Zhou: “That’s called the four-fire brother.”

This name sounds interesting.

Zhao Dsaid with a smile : “My name, you know, the Junior Brother, what is your name, let me know.”

“Lu Zhou.”

Land… boat?

Zhao D squatted, frowns, and the brain did not turn around for a while.

Walking, the two have arrived at the door of the old Mister office.

Although the office door was open, but out of courtesy, Lu Zhou tapped the door.

Stopped the pen in his hand, Qiu Lao mister, who was writing at the desk, looked up.

When I saw the man who appeared at the door, the old mister first slammed down, and then the brow that was locked because of thinking, stretched a kind smile.

“Hey, rarity,” put down the pen in his hand, Qiu Lao mister got up from the chair and smiled and greeted him at the door. “What kind of wind blows you out of Princeton’s cabin?”

Lu Zhou laughed, modestly said: “There was a little bottleneck in the study, I want to ask you some questions about partial differential equations.”

Looking at Qiu Lao’s attitude towards the young people, Zhao D, who stood at the door, crashed on the spot and stood there with a stern look.

At this moment, he always thinks about it, that is why the sense of sight comes from…

Thinking of the forced squad of the big man for a long time, he suddenly shyly wanted to find a seam on the ground.

Didn’t notice the change in the expression on the face of the man at the door. After hearing the explanation from Lu Zhou, the eyes of Qiu Lao’s mist suddenly flashed a expression of interest.

“Partial differential equations? This is the area I am familiar with. Can you tell me exactly what direction?”

“Related to the NS equation.”

Slightly stunned, the expression of interest in Qiu’s old mister is getting stronger and stronger.

“NS equation? This is an interesting question… Let’s sit down first, I am going to find my teapot. I am afraid this topic will be over for a while.”

Lu Zhou nodded, sit down beside the tea table.

At this time, Qiu Lao mister suddenly noticed that the person still stood at the door, slightly hesitating.

“……you are?”

Zhao D quickly stood up and said: “I am Zhao D, reading Bo at the Natif Professor!”

“Oh, Nadius Professor’s student,” Qiu old mister hesitated, pushed the glasses, “…then you sit?”

“No, no,” Zhao D shook his head and scratched his head. Forced a smile and said, “I just came with the Foundation Professor, and I don’t bother the two big men to discuss the business.”

Although listening to the big questions about mathematics, it is certainly helpful for my research.

But sitting next to the two great gods, the pressure on him is too big for a small transparency…

“It’s all about learning. There’s nothing big about it.” Hearing this interesting speech, Qiu Lao’s mister laughed and waved at the young people. “Come and sit down, say, and have a cup of tea. Go again.”
